I/O System Introduction

The Continuum I/O system is comprised of a series of modules separated by function that connect via a common electrical communic ations bus. Each functional com ponent is enclosed in a plastic c as e c ontaining all of its connections to the outside world. Modules are connected t o a centr al c ontroller via a standard fiv e c onduc tor connector.

The Continuum sy stem inc ludes at least one power supply and a single cont r oller module. I/O m odules pr ov ide the controller with the ability to interface with t he outside world. They c onnec t direc tly and communicate with the CPU. T he following is a typical architecture drawing of a Cont inuum System:

Power-CPU Connections

The Continuum Net Controller CPU module includes a c onnec tor on the upper right side of its case f or fur ther distribution of the 24 VDC input power and s pec ial I/O communications s ignals to all I/O modules. Continuum I/ O modules us e these signals for power and comm unic ations as well.

The power-I/O c onnec tor is a five pin male assembly that is designed to eas ily ins er t directly int o the left side (input) connect or of any I/ O module. The signals within that connector are as follows:

PIN Function

5 +24 VDC 4 24 VDC Return 3 Ground 2 Comm B 1 Comm A

The system power s upply gener ates a +24 VDC source for all modules in the syst em. This power sourc e is received through the input power c onnec tor on the left side of the CPU module and sent through to pins 4 and 5 of this connector. Pin 3 (Ground) is intended as a signal ground connec tion.

Communications between the CPU and I/O modules is through a two-signal serial interface that can be internally conf igur ed as either RS 485 or Echelon LON FTT-10. Pins 1 and 2 (Comm B and Comm A) provide the electrical connection for this interface.

Connecti on of I/O Modul es

y

The CPU can directly c onnec t to I/O without the use of cables thr ough a system of built-in plugs and jacks. All I/O modules include two complementary module interconnectors.

Creating a system is as simple as physically plugging the modules together.

Power Suppl

CPU

I/O

In vertical extended systems, I/O modules may be located above or below other modules. In this c as e, cable as s em blies br idge the I/O modules together .

The cable necessar y to connect the CPU and external I/O modules is f iv e c onduc tor and would be attached using a plug-in screw terminal connector. Connect ion between the modules is one- to-one straightfor war d wir ing as s hown below:

Maximum Number of I/O Modules

There is no operat ional lim it to the number of I/O modules connected to the CPU except the capacity of t he power s upply . It is pos s ible to insert auxiliary power supplies into the I/O bus to increase the number of modules support ed.

To determine the maximum number of I/O modules your system can support, subtract the power requirements for each module from the maximum available f r om y our power supply.

PS 120/240 AC 50 U, UPS power supply pr ov ides 35 Watts of power

•

PS 120/240 AC 50, non-UPS power s upply pr ov ides 50 Watts of power

•

PS –48 DC 50, Battery operated power supply provides 50 Wat ts of power

•

NetController r equir es 15 Watts of power

•

Start by subt r acting the NetController from the power av ailable from your power supply .

PS 120/240 AC 50 U

35 – 15 = 20 Watts of available power f or I/ O

PS 120/240 AC 50

50 – 15 = 35 Watts of available power f or I/ O

PS –48 DC 50

50 – 15 = 35 Watts of available power f or I/ O

The power requirements for each I/O module is list ed in the

Reference Guide

ACC # 30-3001-499 and can be found on indiv idual data sheets.

Continuum I/O System

Maximum Length of I/O Bus

A repeater is nec es s ar y if the cable lengths get too long. The following are recommendations r egar ding c able lengths for both RS - 485 and FTT- 10 interfaces:

RS-485 Repeater required if length is >2000 ft. (610 m) or after 32 m odules . FTT-10 Repeater required if length is >8858 ft. (2700 m) bus topology

>1640 ft. (500 m) free topology

Connecting Remote I/ O Modules with RS-485

The Continuum sy stem allows I/ O modules to be placed in a remote location from the CPU (NetContr oller ) . However, long cable lengths can c aus e s ignal c om m unic ations problems on the Power /I - O bus.

When locating an I /O module remotely it is necessary to add a 120

terminator to the

Ω

bus to compensate for the distance. The terminat or m ust be c onnec ted at both ends of the bus for proper operation.

Individual Module Characteristics

This section of the document describes the various I/O modules and presents interfacing information. Each module is presented in it s own mini-sec tion. The part number designator for the module being described is printed on the outer edge of each page.

General Wiring Concerns for All Modules

Do not remotely gr ound any part of t he input sensor wiring. Remote gr ounds c onnec ted to the return t er m inal c ould m ak e the syst em oper ate incorrectly or damage the equipment. T he s ignal r eturn is not true earth ground. It is an elect r onic r eferenc e point necessary t o interpret the sensor properly.

It is recommended that you run input wiring in a conduit s epar ate from AC power or output wiring and avoid long wir ing r uns .

For reliable input oper ation, follow thes e input wiring guidelines:

Never lay wires acr os s the surfac e of a printed circuit board.

•

Wires should never be within 1 in. or 25 mm of any component on a printed

•

circuit board. Use shielded input wire.

•

Terminate the shield of the input wires at one end of the r un only—preferably at

•

the end where your I/O module is loc ated. Be careful when stripping wire not to drop small piec es of wire ins ide the cabinet.

•

Don’t run your input wir ing in the same conduit with AC power.

•

Don’t run your input wir ing in the same conduit with your output wir ing.

•

Grounding the Modules

Each module includes a screw terminal connection for Earth ground. It is important that this connect ion be m ade as c los e to the module as pos s ible.

Caution Do not externally ground any input signal connected to the modul e. This may damage the unit. Sign al return terminals are not connected to Eart h G round.

I/O Connections

The actual input connect ions are located on a twelve-position removable screw terminal connector located at the bottom of the module. Input wir es s hould enter from either the top or bott om wiring t r oughs , and should c om e from the left side of the rack (by convention).

The inputs are labeled IN1, IN2, IN3, and so fort h. Eac h pair of inputs is followed by a connection labeled RET for the input signal retur n, resulting in a sequence of I N1, I N2, RET, IN3, IN4, RET, and s o on. F or any given input, you should use the closest r eturn terminal either before or after that input —the nex t return terminal goes with t he next two inputs, and so on.

The twelve-pos ition connector allows for eight inputs and four signal ret ur ns . The diagram below indicat es wher e eac h input number is located in the terminal block.

Each input includes a low- pas s filter after the pull-up f or m ed by a series r es is tor and a parallel capacitor. The resist or is utiliz ed for over-voltage prot ec tion in limiting current t o two protection diodes (not shown). Not e als o that all input returns are combined and must be directly connec ted to earth ground. It is possible to have more than one input share a single return wire. Keep in mind that the current through eac h input is approximately

Pull-up Ref erence Resistor Selection Switches

In some measuring inst anc es it is desirable that ther e be no pull-up resis tor. Instead of physically remov ing or c utting the resistor off the pr inted circuit board, the input m odule includes a pull-up resistor selection switch (labeled Swdis in the diagr am ) for each input position. T his s witch allows you to select whether or not y ou want a pull-up r es is tor in the circuit. A small 8- pos ition switch module is access ible from the front of the module when the door is opened.

Input Voltage Range Selection Switches (UI-8-10-10V Only)

The UI-8-10- 10V m odule allows y ou to choose from two input voltage ranges. Selection is accomplished by us ing a s witch arrangement that is sim ilar to the operation of the pullup resistor s witches. The Voltage Range switc hes allow y ou to select a range (0-5 V) or (0-10 V) for each input .

The 0-5V range allows c onnec tions to signals that do not exc eed 5.00V. The 0-10V range allows connection t o s ignals up to 10.00V. In this mode the circ uit actually uses the same input measuring cir c uit as the 0-5V range, however , it div ides the voltage present by two thereby limit ing the internal circuitry to 0-5V. When you read a 0-10V input the actual reading will be 0-5V. You m us t adjust your readings for the higher r ange v ia formula.

Switching to 10V inputs dramatically low ers the imp edance of the input to

4.4 KΩ.

This small 8-pos ition switch module is located to the right of the pull-up selector s witch and is accessible f r om the f r ont of the m odule when the door is opened.

I/O Connections

The actual input connect ions are located on a twelve-position removable screw terminal connector located at the bottom of the module. Input wir es s hould enter from either the top or bott om wiring t r oughs , and should c om e from the left side of the rack (by convention).

The inputs are labeled IN1, IN2, IN3, and so fort h. Eac h pair of inputs is followed by a connection labeled RET for the input signal retur n, resulting in a sequence of I N1, I N2, RET, IN3, IN4, RET, and s o on. F or any given input, you should use the closest r eturn terminal either before or after that input —the nex t return terminal goes with t he next two inputs, and so on.

The twelve-pos ition connector allows for eight inputs and four signal ret ur ns . The diagram below indicat es wher e eac h input number is located in the terminal block.

The DM-20, Continuum’s Digital Input and Output m odule, provides high density, versatile I /O for m any cont r ol applic ations. When coupled with t he optional DIO-20 Expansion Board, the DM-20 allows you to mix and match up to 20 digital inputs and outputs. Us ing standar d off-the-shelf digital I/O blocks, the DIO-20 allows the system designed to meet a wide r ange of applications, inc luding ON-OFF or pulse-width modulation (PW M ) cont r ol of equipment and for switching induct iv e loads up to 240VAC. The DM-20 provides 24 V DC power to the DIO- 20 v ia a separat e c able as s em bly .

When used without the DIO- 20 E x pans ion B oar d, the DM-20 can control any combination of inputs and out puts, up to a total of 20 per module. The DM-20 can be used to drive/sense up to 20 LEDs and/or switches on the Continuum enclosure’s door-mount ed GA-40 or GA-80 Graphic Annunciator Panel via an easy-to-use 25-pin cable assembly and built-in terminal blocks.

DIO-20

Using the DM-20/ DIO - 20 Combination

The DIO-20 provides the DM-20 with a real-world inter face to its I/O channels. Solid-s tate input modules (on t he DIO - 20) pr ov ide interface circuitr y to a variet y of signals . These modules convert their signals to digital levels for input to the DM-20.

Similarly, s olid- s tate output modules (on the DIO-20) allow the digital levels of the DM-20 to interf ac e to a var iety of signals .

In both cases, the I/O points are set up to have an Electric al Type of what type of solid-s tate module is installed.

For more inf ormat ion on the DIO-20, refer to its User Manual.

GA-40/ GA-80 Int erf ace

The GA-40 and GA-80 Gr aphic A nnunc iator Panels provide the capabilit y of creating custom display and c ontrol panels attached to the Cont inuum NE M A enclosur e or to an auxiliary panel. T hes e panels pr ov ide a c onnec tion for up to 40 (GA-40) or 80 (GA - 80) input switches or output LEDs. You can mix the number of switches and LE Ds as needed.

The connection between the DM-20 and the GA-40 and GA-80 panels c ons is ts of a 25pin ribbon cable to supply data between the modules and a three-conductor power cable.

Data connection between the two is accomplished v ia a 25- pin m ale DB 25 c able that is permanently at tached to the GA panels.

The GA-40 provides interfaces for 2 DM-20 modules. The GA-80 provides interfaces for up to 4 DM-20 modules.

DO-4-R

The DO-4-R, Cont inuum ’s digital output module, has four Form C relay outputs, rated at 5 amps, 240 VAC. These ver s atile out puts make the DO-4-R an excellent c hoic e for switching mot or star ters and other inductive loads up to 240 VAC, with either two position (on/off ) or pulse-width modulation (PWM) c ontrol. The PWM feature permits the modulation of valv es and dam per s to 0.1 second resolution. Two adjac ent Form C relay outputs can be c om bined in s oft war e to provide a Tri-state out put, for bi- dir ec tional control of v alv es and dam per s and other end dev ic es . Metal oxide varistors and 5000V isolation on each output ensure reliable noise-f r ee oper ation.

A DO-4-R-O model with f ull ov er r ide c apabilities is also available. E ac h output has a local hand-off-auto switch, which enables ser v ic e per s onnel to override the out put. The switch also provides overr ide feedback of output values for use in troubleshooting or test conditions. A loc al indic ator light for each output displays relay stat us. A nother LED provides override s tatus.

DO-6-TR

The DO-6-TR, Continuum ’s triac output module, has s ix Form A triac - bas ed outputs, rated at 0. 5 amps, 24 VAC, f or cost-effective on/off or puls e- width modulation (PWM) control of lighting, heat, and fan unit s. The PWM feat ur e per m its the modulation of valves and dampers to 0. 1 second res olution. Adjacent outputs can also be configured in pairs to provide up to three Form K, Tri-state outputs for bi- dir ec tional control of dampers and valves.

Metal oxide varis tors and optocouplers on the DO-6-TR provide 2500V isolation on eac h output, ens ur e nois e- free operation, and, in most c as es , eliminate the need to install MOVs in the field.

I/O Connections

The actual output connections are locat ed on a thirt een-position removable screw terminal connector located at the bottom of t he module. Output wires should enter from either the t op or bottom wiring troughs, and should c om e from the r ight side of the rack (by convention) .

The outputs ar e grouped in pairs of two connector terminals per c hannel. Each output presents a norm ally open s ingle pole s et of contacts.

The diagram below indicat es wher e eac h output number is located in the terminal block.
