ABB GJR5252300R0101 07AC91-AD2:Analog Conf.In./Output module
The ABB 07AC91-AD2 is a 24 V DC configurable analogue I/O module with 8 inputs, 8 outputs, voltage/current signal support, 12-bit resolution plus sign and CS31 bus communication for industrial automation.
Why Choose the ABB 07AC91-AD2 Configurable Analogue I/O Module?
The ABB 07AC91-AD2 is a configurable analogue input/output module for industrial automation systems using the CS31 bus. It connects analogue field signals to a compatible control system, supporting measurement acquisition and the delivery of control references to connected equipment.
Combining analogue inputs and outputs in one module helps engineers organise process signal connections within a distributed control installation. Input measurements can inform the controller’s application logic, while output signals communicate the resulting commands to suitable receiving devices.
ABB identifies this model with 8 analogue inputs and 8 analogue outputs, voltage/current signal capability and 12-bit resolution plus sign. It operates from a 24 V DC supply and features pluggable terminals.

Analogue Signal Handling for Industrial Automation
Analogue input modules convert electrical measurements into values that a controller can process. In a typical application, a compatible transmitter represents pressure, level or another process variable as an electrical signal. The control programme interprets that measurement and determines the required response.
Analogue outputs provide electrical references to compatible actuators, drives or other receiving equipment. Correct operation depends on matching the configured signal type, wiring and scaling to each device. ABB’s 07AC91-AD2 product specification identifies the module’s electrical and connection configuration.
Typical Applications
- Process measurement using compatible analogue transmitters.
- Pressure and level monitoring in industrial systems.
- Analogue reference signals for compatible variable speed drives.
- Control of equipment accepting voltage or current commands.
- Distributed analogue signal acquisition on CS31 networks.
- Maintenance of compatible ABB automation installations.
