ABB Digital output module ICSO 08 R1, 8 relay outputs 2 A

Intended purpose

The digital output module ICSO 08 R1 is used as a re

mote module on the CS31 system bus. It contains 8 relay

output channels with the following features:

The relay outputs

are electrically isolated (from each other and

from the rest of the module and

can be loaded with 2 A.

The module is available for supply voltages of 24 V DC

and 230 V AC. For electrical connection, it has to be

mounted on a plug-in base ECZ.

The CS31 system bus interface is electrically isolated from

the rest of the module.

The module offers a number of diagnosis functions (see

chapter "Diagnosis and displays").

Electrical connection

The module has to be mounted on the plug-in base ECZ

and then fastened with two screws. The plug-in base has

a mechanical coding which prevents that a module can

be plugged-in with another supply voltage than set on the

ECZ. Before mounting the input module, the mechanical

coding has to be set to the correct supply voltage.

The following three figures show the electrical connection

of the output module.

Addressing

An address must be set for each module to enable the

basic unit to correctly access the outputs.

The address setting is accomplished with the DIL switch

on the plug-in base ECZ. When using the basic units

07 KR 91 and 07 KT 9x as bus masters, the following

address assignments are valid:

A detailed description about "Addressing" can be

found in the chapter "Addressing" of the basic units

and couplers.

The module uses 8 outputs on the CS31 system bus.

I/O configuration

An I/O configuration is not necessary.

Normal operation

After power ON the module initializes automatically.

During this period the red LED (3) flashes.

After initialization the red LED (3) goes out, if the bus

runs correctly and if the module has detected no error.

The 8 yellow LEDs (1) indicate the signal statuses of

the channels A0...A7.

Diagnosis and displays

Diagnosis functions:– Error inside the module– Error on the CS31 system bus

If one of these errors occurs, the red LED (3) lights up.

Using the test button (4) and the LEDs (1), diagnosis in

formation can be achieved directly at the module.
