ABB 07AC91 GJR5252300R3101 Analog I/O module

ABB 07AC91 GJR5252300R3101 Analog I/O module

Functional Description

The 07AC91 GJR5252300R3101 is an Analog I/O module designed for ABB's Advant Controller 31 series. It

contains 16 analog input/output channels that can be configured in two operating modes:

• Operating mode "12 bits": 

8 input channels, individually configurable ±10 V or 0...20 mA, 12 bit resolution plus 8 output channels,

individually configurable ±10 V or 0...20 mA, 12 bit resolution

• Operating mode "8 bits":

16 channels, configurable in pairs as inputs or outputs, 0...10 V oder 0...20 mA, 8 bit resolution

• The configuration is set with DIL switches.

• The PLC offers an interconnection element

ANAI4_20 for measuring signals of 4...20 mA (refer to 907 PC 331, connection element library).

The module 07 AC 91 uses up to eight input words on the CS31 system bus plus up to eight output words. In

the operating mode "8 bits", 2 analog values are packed into one word.

The operating voltage of the unit is 24 V DC. The CS31 system bus connection is electrically isolated from the

rest of the module.
