cur whenever working

on

this product. Protec­tive measures and safety procedures should be
observed at all times.

NOTE:

The IP-98 Series of Power Supplies Contain High Voltages.

Do

Not Handle Com-

ponents With Power Applied to the Unit.

THEORY

OF

OPERATION:
GENERAL: The IP-98 and IP-981 U series of
switching type power supplies convert the rated
input power into three separate DC output volt­ages, (+5

V,

+15V,and -15 V).

INPUT: The input voltage, dependent upon the
version purchased, is applied to the power sup­ply viathe ON/OFF switch S1. Fuse

F1

provides
protection from input and output current over­loads.

EMI FILTER: Transformer

T1

and associated

components

C1

through C5 form a multi-func­tion filter. This filter reduces line noise on the
power source from entering the supply as well
as filtering switching noise generated within the
supply from returning to the source.

RECTIFIER: On AC units

CR1

and C6 rectifies

the 60 Hz power. The rectifier circuit is omitted

on 12 and 24 Vdc input units.
PULSE

WIDTH

MODULATOR

(PWM): The

PWM (U1) is powered from 15 V produced by

01

and associated circuitry. Resistors R3,

R4

and C12 provide a soft start

for

U1. The pulse
width modulator switches at a 50 kHz rate. The
switched signal is fed to

04

via

02

and

03.

This
signal then modulates the source voltage through
T2.

U3

provides the reference voltagefor under and

over voltage protection which controls op-amp

U4. Potentiometer R10

is

a factory adjustment
which sets the +15 V level. Voltage feedback to
the PWM

is

optically coupledinU2 to provide

input/output isolation.
OUTPUT:

04

through

07

rectify the +5, +15, and

-15 Vsections oftransformer T2. Output filtering

is

accomplished via L1,C18, and C19on the +15

V output, (L2, C15,

&C16 on the -15 V and L3,

C17,

&

C21

on the +5 V). Regulator U5 provides

current limiting on the 5 volt bus.

INSTALLATION:

GENERAL: Series 98 equipment is supplied

in

various forms depending on the application
and system purchased. When supplied loosethe
module

must

be installed in a chassis and
interwired. The method of bringing out the mod­ule inputs/outputs to the rear of the chassis is
via an I/O connector (input/output). The I/O's are
available

in

various styles, depending on appli­cation, and are purchased separate from the
module. This section of the manual covers the
most common supplied methods. Separate in­structionswill accompany equipmentnot covered
herein.

UNPACKING: This equipment may be sup-

plied loose, mounted

repairing this equipment. INIVENICONOLOG CORP. assumes no liability for failure to observe
standard or specifically noted safety requirements or to use this equipment for purposes other than
intended.

GROUNDING: A suitable ground is required to reduce the hazard of shock. Refer to the enclosed module,

chassis, and/or cabinet wiring diagram for ground connection locations.
ENVIRONMENT: Operation

of

any electrical equipmentinany area containing gases, fumes, wet, or damp is

a potential safety hazard. Necessary precautions should be taken.
MANUAL: Operators and maintenance personnel should read this manual before installing the equipment

and placing itinservice. Only properly trained personnel with proper tools and equipment should operate,
maintain, repair,

or

service this equipment.

SHOCK: Potentially dangerous electrical shock can occur whenever workingonthis product. Protective
measures and safety procedures should be observed at all times.

THEORY OF OPERATION:

GENERAL:
The telemetry transmit I/O takes a voltage

or

current input and converts it to a square wave output at a

specific frequency. An example would be a unit with a 4-20mA input at a 10-30Hz Rate. On a scale

of

0 to

100, 4mA is 0 and 20ma

is

100. That same scale applies to the outputof10-30Hz. 10Hz represents 0 while

30Hz is 100. When the 4mA input from a transducer or other source

is

present at the transmit I/O module

(I/O 40T), the output

of

the I/O module is 10Hz. Any increaseinthe input current has an equal percentage

increase on the frequency of the output. The lowest frequency

in

the range is commonly referred to as "Left

Scale" and the highest, "Right Scale".

The square wave output from the I/O 40T modulates a FSK transmitter (IT-98DSP) operating

in

2 frequency

mode at the appropriate rate to match the input current (or voltage).

The FSK receiver (IR-98DSP) receives the output from the FSK transmitter and produces a square wave

:output at the same modulated rate from that of the transmitter. The I/O 40R converts the modulated

frequency to a current (or voltage) output. It

is

not required that the transmitter input and the receiver

output current (or voltage) be the same.

I/O 40T (TRANSMIT I/O):
U1

is a precision, differential amplifier. The DC input signal is applied to the (+) and (-) input terminals. If

thE

input signal is a current, then shunt resistor

R1

is supplied to convert the input current to a voltage. Noise is

filtered by R2,

R3,

R18, R19,

C1

and C2.

In

millivolt applications the gainofthe differential amplifier can

be

increased by including

R4.

U3B and associated circuitry form an inverting, summing DC amplifier. The output voltage is positive and
drives U4 voltage to frequency converter. U4's input voltage, R13, R14 and C8 control the output frequency
which is a few thousand Hertz at right scale. The high frequency allows use

of

small, temperature

compensated frequency determining components.

U4's output is divided down to the desired frequency by U5 (12 stage counter/divider). The output of U5

is

buffered by U6. This signal is used to key the FSK transmitter between Mark & Space.

U2

is a precision +5VDC reference voltage generator which supplies the source for the calibration voltage

divider. The reference voltage is inverted by U3A to provide a negative reference.
The (+) and (-) reference voltages are used for offset and bias.
A bias signal is required if the output frequency ratio is not equal to the input ratio. No bias is required if 1-5V

or 4-20mA is to produce a 5-25Hz output because the in/out ratios are the same. However, as an example,

if ±1V input is to produce a 10-30Hz output, then 0.816V must be applied to U4 when the input

is

-1V

and

2.45V applied when the input is +1V. U3B is the summing amplifier that combines the outputofU3A with a

reference bias to convert the ratios. Span is controlled byR5and bias by

R9.

ANALOG ISOLATION OPTION: U8 is a DC to DC converter which provides isolation for the +15 and

-15/

voltages. This isolation is rated at 1000VDC from input to output.

I/O 40R (RECEIVE I/O):
The incoming square wave from the FSK receiver output is applied to

R1

and buffer U1A. U1A's output is
applied toU1B and delay circuit R2 and C1. This circuit will pulse high twice per input cycle. If the incoming
signal is 10Hz, the outputofU1B will be 20 pulses per second.

Y1

is a 2MHz crystal which controls the

oscillator circuit U2C,

R3,

R4 and C2. U2C is applied to timer U3 that runs the clock. U2Aisused to reset the

clock every 1/2 cycle. When the clock times out, then U3 signals to U2B that it is finished. U2A is also used

to start U4 (FET switch).

The generated wave form controls the FET gatesofU4 which alternately switch a precision reference voltage
on and off. The switched reference voltage drives averaging filters

R9,

RiO, C5, C6 and U6C. The output

of
U6C is a DC voltageinthe 0.5 to 2.5V range and is precisely proportional to the incoming telemetry frequency
signal.

U5 is a precision 5V reference. R5, R6 and U6D give a negative 5V reference to the summing amp circuit R7,
R8,

R11, R12, R13 and U6A.

At this point the signal enters the voltage to current circuit. If current is not required it acts as an inverting
buffer circuit which consists

of

U7,

02,

03,

R19, R20 and U6B.

An optional4-20mA current buffer circuit for loop supplies is performed through

04

and R21.

LOSS OF TELEMETRY: BufferU1D accepts a signal from input signal buffer U1A.

U1

D outputs to holding

I circuit R16, R17, R18

D1

and C9. This circuit turns

present.

INSTALLATION:

GENERAL:
Series 98 equipmentissuppliedinvarious forms depending on the application and system purchased. When

supplied loose the module must be installed

in

a chassis and interwired. The methodofbringing out the

module's I/O's (inputs/outputs) to the rear

of

the chassis is via an I/O module such as the I/O 40T and the I/O

40R. To facilitate the 98 Series equipment's ability to work

in

almost all applications, several typesofI/O's are

available and are purchased separately. This section

of

the manual covers the most commonly supplied

methods. Separate instructions will accompany equipment not covered

in

this manual.
UNPACKING:
This equipment may

be

supplied loose, mountedinan individual chassis, stacked interconnected chassis, or

as part

of

a rack or cabinet. Follow the procedure for the typeofsystem supplied.

Loose and/or equipment mounted

in

an individual chassis will be packedinits own shipping carton. Inspect

the carton for possible damage

in

transit. Open each carton carefully and remove the contents. Inspect the
equipment for possible damage. Verify all items have been removed prior to discarding any packing
material.

Note: It is suggested the carton be retained forpossible onward shipment.

Interconnected chassis or equipment suppliedinracks or cabinets will be suppliedinspecial boxes, wood

crates,

or

if shipped via air-ride van without any case. Inspect the crate or other packing for possible damage

in

transit. Carefully remove the equipment from the container and inspect it for possible damage. Verify all

items have been removed from the crate prior to discarding any packing material and refer to the note above.
Should transit damage be found please notify INIVEN immediately.
MOUNTING:
After unpacking follow the appropriate mounting procedure.
LOOSE MODULE: (The following is for new installations) Each I/O module is shipped with two Card Guides

which are to be mounted

in

the chassis (some INIVEN chassis' may have the Card Guides already mounted).
Viewing the chassis from the front, the recommended arrangement is a power supply on the extreme left,
followed by transmit and or receive modules working towards the right of the chassis. Locate the desired
position within the chassis for which the module is to

be

placed. Remove any existing blank panels. From the

front

of

the chassis and with the boss (rounded) side facing to the right, press the lower card guide into the

holes provided. Repeat this procedure for the upper card guide.
The I/O 40T and the I/O 40R are made up

of

two boards, the I/O 40 itself and the terminal block board. These

two boards are connected at right angles. Disconnect the two boards for mounting.
The I/O 40 modules are installed from the front

of

the chassis by connecting it to the appropriate tone module

(i.e. the IT-98DSP for the I/O 40T or the IR-98DSP for the I/O

40R).

The connection between the I/O module

and the tone module is secured using 4 screws mounted through the existing holes

in

the connectors that

mate the two modules.

Install the combined I/O 40 board and tone module by sliding it into the front of the chassis using the same/'

Card Guides. Once the module is firmly seated, use the flat blade screwdriver to turn the two quarter turn
screws clockwise

on

the front panel.

The I/O's terminal block board must be mounted from the rearofthe chassis. Align the terminal block board
with the I/O 40 and firmly mate the boards. To secure the board

in

place, turn the two quarter turn screws

clockwise using a flat blade screwdriver.

INDIVIDUAL CHASSIS: The chassis is 1 or 3 rack units high and have two mounting brackets for either
mounting on a wall or a standard 19" rack. All brackets and hardware are included with the chassis with the
exception

of

the mounting screws for the brackets to be attached to a wall or rack. Spacingofthe holes

on
the brackets are compliant with EIA and DIN standards. Slide the equipment into the rack or cabinet and
secure it with proper screws for the mating hardware being used. Tighten all screws.

INTERCONNECTED CHASSIS: (or equipment mounted

on

shipping rails) This equipment should be
mounted similarly to an individual chassis. When shipping rails are provided the equipment is to be placed
near the desired location. Remove the screws holding the shipping rails and then remove the rails. Slide the
equipment into the rack or cabinet and secure it with proper screws for the mating hardware being used.
Tighten all screws.

Systems provided

in

a rack or cabinet from the factory must be secured to the floor or wall as required.

Mounting hardware is not supplied due to the various surfaces and mounting methods.

CAUTION: EQUIPMENT MOUNTED

IN

SWING RACK TYPE CABINETS MUST

BE

SECURED TO THE
MOUNTING SURFACE PRIOR TO OPENING THE SWING RACK TO PREVENT THE CABINET FROM
FALLING.

VENTILATION:
Proper ventilation is required for most electronic equipment. Enclosed cabinets or rooms where this equipment

is mounted should be kept at temperatures within the limits

of

the equipment. Operation above these limits

may affect reliability.
ELECTRICAL CONNECTIONS:
User connections are made via the I/O modules

on

the rearofthe chassis. Each unitinthe 98 SERIES

of
equipment will contain these connectionsinthe instruction manual for the specific individual module. On
equipment supplied wired from the factory or

on

interwired chassis and cabinetsan"as supplied" drawing will

be included with the equipment. When supplied, external wiring should be

in

accordance with the "as supplied"

drawing. See figures 2A and

28

for wiring connections.

For safety reasons power on the leads to

be

connected to the unit is to

be

de-energized during

installation.

Methods

of

making the wiring connections to the terminal blocks vary and are based

on

local practice. It is

suggested number 20 AWG size insulated wire, stripped portion tinned, be used. Approximately 1/4"

of

the

insulation is to be removed and inserted

in

the terminal block. Module power and tone lines may be

daisychained should the application require.

Tighten all connections and insure exposed wires do not touch each other or the chassis.

INITIAL START-UP & LEVEL CHECKS:

GENERAL:
To verify readings it is suggested the entire system

be

checked from the input process being measured to the

output indicator or recording device.

EXAMPLE: If a transducer is measuring pressure, check it with a separate accurate pressure gauge

and··

compare the readings with the output at the receiving station indicator.
RECEIVER: The telemetry frequency input to the receive I/O must be as close to a symmetrical square wave

as possible. If the FSK tone receiver (Le. IR-98DSP) is equipped with Mark and Space relays they must be
removed. Adjust the receiver bias control for a square wave following the instructions for the particular I/O 40
module being used.

TRANSMITTER: When the I/O 40T is

in

use with the IT-98DSP, the IT-98DSPisoperatinginthe Space hold

mode. Therefore

on

the front panelofthe IT-98DSP, under normal operating conditions the Space LED will

not be lit and the Mark LED will be turning on and off relative to the keying frequency being used (example:

10

times per second for 10Hz).

CALIBRATION:

Note: The I/O 40T and I/O 40R have been calibrated at the factory before shipment and should not require

any further adjustment. Field adjustments to these units are not recommended. The following procedures are
made available for units

in

which accuracy associated components have been field changed.

Span is defined as the entire range for which the unit is set. An example is a range of±1V. The Span ofthis

range is 2 volts. Bias is defined as the adjustmentthat can offset the Span along the scale. Using the above
example, the Bias permits the adjustment

of

the

2V

Span down the scale to

-1.1

V to

+0.9Vor

up the scale to

-0.8V

to +1.2V and so on.

Note:

The

sample rangeof±1

V @ 10-30Hz will be used in the following calibration procedure as an example.

ALIGNMENT OF I/O 40T:
The following equipment is recommended to align the transmit endina test environment with the I/O

40T

removed from service:

1.

Precision voltage or current source as required for the input range purchased.

2. Digital voltmeter that can resolve 100 micro volts (DVM).

3.

Frequency counterwith 10 period averaging.

4. Flat blade screwdriver with 1/8 inch wide tip or potentiometer adjustment tool.

5. Test power supply to power the I/O 40T.

Calibration is performed by adjusting two potentiometers, R5

for

Span and

R9

for Bias.

STEP

1:

Apply the highest voltageorcurrentinthe rangeofthe I/O

40T

to the positive analog input TB-5 and

to negative analog input TB-6. For the exampleof±1V @ 10-30Hz, +1V would be applied.
STEP 2: Connect a frequency counter to the square wave output TB-8 (or

JP1

pin B if an extender board is

being used) and square wave common output TB-1. Note the reading.
STEP

3:

Apply the lowest voltage or current in the rangeofthe I/O

40T

to the analog input TB-5 and to
negative analog input TB-6. For the exampleof±1V @ 10-30Hz, -1V would be applied. Note the reading on
the frequency counter. The Span (the first reading minus the second reading) should for this example equal
20Hz for frequency and 2V for voltage.

STEP

4:

If the Span is less than it should be, adjust R5 counterclockwise. If the Span is greater than it should

be adjust R5, clockwise until you have reached the desired Span.

Note: It

may

be easier to adjust R5 in small increments while repeating STEPS 1-4 until the desired Span is

obtained.

Once the correct Span (in this example 20Hz) has been set then the Bias can be adjusted.

STEP 5: Repeat STEPS 1

& 2 and note the reading from the frequency counter. For the example

of±1V @

10-30Hz, the reading should be 30Hz. If the reading is higher then it should be, adjust

R9

counterclockwise

or

clockwise if it is less then it should be.
STEP

6:

Once the upper frequency has been set (30Hz in this example) repeat STEP 4 to verify that the

lower frequency

in

the range is correct (10Hzinthis example). If the lower frequencyisnot accurate, the

Span may need to be fine tuned and the entire procedure should be repeated to ensure accuracy.

Note: It

may

be easiertoadjust R9 in small increments while repeating the adjustment procedure.

IMPORTANT: When R5 or R9 are adjusted, itisimportant to allow the new setting settle before making any

further adjustments.

I

Note: The sample range

of±1V @ 10-30Hz will be used in the following calibration procedure as an example.

ALIGNMENT OF

110

40R:

The following equipment is recommended to align the transmit endina test environment with the I/O 40R
removed from service:

1.

Square wave frequency generator which can be set within .02% of input range frequency. Output

I.·

voltage must swing between 0 and +15VDC.

2.

Digital multimeter for current and voltage with 4~digit accuracy.

3.

Test power supply to power the

110.

Calibration is performed by adjusting two potentiometers,

R11

for Span and R7 for Bias.

STEP1:Using the frequency generator, apply the highest frequency or right scaleinthe rangeofthe

110

40R

to the Telemetry Signal input TB-9 and Square Wave common TB-1. For the example

of

±1V @ 10-30Hz,

30Hz would be applied.

STEP2:Connect the multimeter to the analog output of the 1/0 40R, TB-5 for positive and TB-6 for negative.

Note the reading.
STEP

3:

Adjust the frequency generator to apply the lowest frequency or left scaleinthe range to TB-9 and

TB-1. Note the reading. For the example of ±1V

@ 10-30Hz, 10Hz would be applied. The Span (the first

reading minus the second reading) should for this example equal 20Hz for frequency and

2V

for voltage.

STEP

4:

If the Span is less than it should be, adjust

R11

counterclockwise. If the Span is greater than it

should be adjust

R11

clockwise until you have reached the desired Span.

Note: It

may

be easier to adjust R11 in small increments while repeating STEPS 1-4 until the desired Span is

obtained.

Once the correct Span (in this example 20Hz) has been set then the Bias can be adjusted.

STEP

5:

Repeat STEPS 1 & 2 and note the reading from the multimeter. For the exampleof±1V @ 10­30Hz, the reading should be +1V. If the reading is higher then it should be, adjust R7 counterclockwise or
clockwise if it is less then it should be.

STEP

6:

Once the upper voltageorcurrent has been set (+1Vinthis example) repeat STEP 3 to verify that

the lower voltage or current (left scale) is correct

(-1Vin

this example). If the lower voltage or current is not

accurate, the Span may need to be fine tuned and the entire procedure should

be

repeated to ensure

accuracy.

IMPORTANT: When

R7orR11

are adjusted, it is important to allow the new setting settle before making any

further adjustments.

Inspect modules for signsofvisual damage such as overheating or corrosion. Correct the conditions

prior to proceeding further.

e.

Use the cloth and mild detergent to clean the front panelofeach module and the frontofthe chassis.

Insure all parts are dry prior to proceeding.

f.

Replace all modulesintheir proper locations taking care to align each module to the Card Guides

in
the chassis. Once each card is firmly seatedinits correct position, use the screwdriver to turn the two
quarter turn screws

on

the front panelofeach module clockwise.

g.

Energize power to the equipment and turn "ON" the power switchonthe power supply.

h.

Perform the initial startup procedure locatedinthe installation sectionofthis manual.

MODULE REMOVAL:

Before removing a module always turn offthe power supply first. To remove the I/O 40 board but not the

terminal block board, turn the two quarter turn screws clockwise on the front panel

of

the tone module

attached to the I/O 40 and pull the module firmly by the handle. The I/O 40 module is attached to the tone

module and is removed from the front

of

the chassis. To remove the I/O 40 from the tone module

(Le.

IT­98DSP) unscrew the two screws attached to the tone module. The connecting brackets should remain with
the I/O 40T or I/O 40R.

To remove the Terminal Block board

of

the I/O 40T or I/O 40R remove the I/O 40 board according to the

above instructions then unwire all connections to the board. Turn the two quarter turn screws clockwise

on

the

rear panel of the I/O 40 terminal block board and remove the board.
To replace an I/O 40T or I/O 40R, follow the Loose Module installation instructions earlier

in

this manual.

REPAIR:

The I/O 40T and I/O 40R have been designed to operate

in

an industrial environment and should provide

years of trouble free operation.

In

the unlikely event a malfunction should occur and factory assistance is
required, a toll free number has been set up, 800-526-3984. Should a module require a repair please refer to
our twelve year warranty

on

the back cover of this manual. All returns require a RMA number, which can be

obtained by calling 800-526-3984.
