Chapter 2 General

General

The SISD isolator receives 1 to 5 V DC input signals and outputs 1 to 5 V DC and 4 to 20
mA DC signals which are isolated from the input signal and the power supply.
With the VJ77 Parameter Setting Tool you can do the following:

• Read/write all parameters at once

• Save read parameters to a file

• Copy parameters to other devices of the same model and suffix code (only with style

code R or S).

3.1 External Wiring

(a) To prepare cables for connection to each terminal, install crimp-on solderless lugs for

4 mm screw on the end of each cable.
(b) Draw the internal unit out from the rack case.
(c) Connect the cables to the correct terminals referring to Table 3-1.
(d) Replace the internal unit into the rack case after completing the wiring.
(e) Always replace the terminal cover after completing the wiring.

The terminal cover cannot be replaced if the internal unit is not installed in the rack
case. The terminal cover should be securely replaced because it has the function of
locking the internal unit.

Chapter 4 Principles of Operation

4.1 Principle of Operation

Input signal Ein passes through high-input resistor Rin (1 MΩ, 0 V input at input burnout),

and is converted into digital data in A/D conversion circuit. The digital data has signal
processing (square root characteristic etc.) in micro-processor to be Pulse Width Modulation
(PWM), then is converted into 1 to 5 V DC or 4 to 20 mA DC signals in output circuit through
optical-isolation circuit.

 Items to Confirm before Start of Operation

Before you start operation, inspect and confirm the following items:
(1) Draw out the internal unit from the rack case, and make sure that the specified fuses are

properly mounted in the fuse holders at the rear of the internal unit.

(2) When inserting the internal unit into the rack case, firmly connect the multi-pin connectors

for connecting the internal unit and the case.
(3) Make sure that power plugs are properly connected to the power outlet.
(4) Make sure that external wiring to the terminal block is properly connected.

The SISD isolator is made for operation by simply turning on the power once the installation
and wiring are completed. The isolator does not require parameter settings and the like if
there is no change in the specifications at order.

(e) Call the adjustment item (P: ADJUST).
(f) P03: ZERO ADJ1 is displayed.
(g) Apply an input equivalent to 0% of the input range. Check the input value and the input

display of P03: ZERO ADJ1. If the input value does not correspond to the display value,
select P03: ZERO ADJ1 to enter the adjustment mode. Mainly select INC (addition) or
DEC (subtraction) for adjustment. (Selecting RST resets the adjusted value and re­trieves the factory-set default.) Selecting HINC or HDEC performs adjustment using a
value ten times as large as INC or DEC.

(h) Apply an input equivalent to 100% of the input range. Check the input value and the

in- put display of P04: SPAN ADJ1. If the input value does not correspond to the display
value, select P04: SPAN ADJ1 to enter the adjustment mode. Mainly select INC (addi­tion) or DEC (subtraction) for adjustment. (Selecting RST resets the adjusted value and
retrieves the factory-set default.) Selecting HINC or HDEC performs adjustment using a
value ten times as large as INC or DEC.

(i) After completing the adjustment, set the parameter write protect (W.P.) of setting jumper

to ON. (Refer to ‘‘5.2 Setting Jumper’’.)

• STATUS is displayed in A54 of A: DISPLAY (display), and SELF CHK is displayed in

60 of each item.

• STATUS error code is to be the addition display (hexadecimal number) when two

errors or more occur.

Power Supply Terminal Connections (Options /TB,
/A2TB, and /REK)

If you specify the terminal block to which the power source is directly connected (option
codes: /TB, /A2TB, and /REK), the external wiring to the terminal block is necessary;
therefore, drawing out the internal unit requires previous turning off of the power source and
disconnection of the wiring from the terminal block.

8.2 Power Supply And Ground Wiring

(1) All cable ends must be furnished with crimp-on type solderless lugs (for 4 mm screw).
(2) Examples of applicable cables:

Cross-sectional area of the cable conductor: 2.0 mm

Applicable cable: 600 V vinyle insulated cable (IV) stranded wires, conforming to JIS

C3307.
Vinyle sheathed cables for electric appliances (KIV) stranded
wires, conforming to JIS C3316.

Note *: Power supply cables should be determined from the instrument power

consumption-they must have conductors with cross-sectional area of at least

1.25 mm

(3) Wirings to power supply and ground terminals should be made after completion of signal

terminal wirings. (To facilitate connecting input signal, pull the internal unit approximately

half way out of the housing. Do not remove the power terminal block.)
(4) After completing the power supply and ground wiring, mount the power terminal cover.

GS 01B04N01-02E

n GENERAL

The Model SISD Isolator accepts a 1 to 5V DC input
signal. The input signal is isolated from the power
supply common and from the Isolator output signal.
There are two outputs: 1 to 5V and 4 to 20mA DC.

With the VJ77 Parameter Setting Tool you can do the
following:

· Read/write all parameters at once

·Savereadparameterstoale

· Copy parameters to other devices of the same model

andsuxcode(onlywithstylecodeRorS).

Lowcut Function: At E1 is less than 1% , the output is
proportional to input.

Output Signals

Load Resistance: At least 2 kΩ(1 to 5 V DC output),

DC(one output)

up to 750 Ω (4 to 20 mA DC output)

BRAIN Communication Function

Setting of each parameter, monitoring of input/output

values, and conguration by a PC (VJ77), JHT200
Handy Terminal* or BT200 BRAIN Terminal*.

*: When connecting a PC (VJ77) or the JHT200

Handy Terminal, the adapter for modular-jack
(model E9786WH) is required. When using the
BT200 BRAIN Terminal of YOKOGAWA Electric
Corporation, the communication cable of 5-pin
connector type (model F9182EE) and the adapter

for modular-jack (model E9786WH) are required.
