Description

The ABB 07 AI 91 (GJR5251600R4202) is a high-performance analog input module designed for integration into the CS31 system bus. This remote module features 8 configurable analog input channels, providing versatile measurement capabilities for industrial automation environments. It is engineered to handle a wide variety of signal types, including temperature sensors and voltage inputs, with integrated linearization for specific sensor types.

Features

8 configurable analog input channels, programmable in pairs.
Supports voltage inputs (± 10 V, ± 5 V, ± 500 mV, ± 50 mV).
Supports current inputs (4...20 mA or 0...20 mA with external 250 Ohm resistor).
Compatible with Pt100/Pt1000 RTDs and J, K, S type thermocouples with internal linearization.
12-bit plus sign resolution for high-precision signal processing.
Electrically isolated CS31 system bus connection for enhanced noise immunity.
Integrated diagnostic functions with automatic self-calibration for all channels.
DIL switch configuration for module addressing and channel settings.

Applications

The 07 AI 91 is primarily utilized in distributed control systems (DCS) and PLC architectures where remote data acquisition is required. It is ideal for monitoring process temperatures, pressure transmitters, and other analog field instrumentation in manufacturing, power generation, and process control facilities.

Installation Guidelines

Ensure the power supply is disconnected before installing or removing the module from the DIN rail.
Mount the module on a standard TH35-15 or TH35-7.5 DIN rail according to IEC 60715 standards.
Maintain adequate clearance around the module to ensure proper ventilation and cooling within the control cabinet.
Use shielded cables for analog signal connections to minimize EMI interference; ensure the shield is properly grounded.
Ensure that only electrically isolated sensors are connected to the input channels to prevent ground loops.
Configure the module address and input types using the physical DIL switches before commissioning.

FAQ

What is the primary function of the 07 AI 91 module?

The 07 AI 91 is a remote analog input module for the CS31 system bus, used to collect and digitize analog signals from sensors like thermocouples, RTDs, and voltage/current transmitters.

Can this module measure 4-20 mA signals?

Yes, the module can measure 4-20 mA or 0-20 mA signals by utilizing an external 250 Ohm resistor connected in parallel with the input channel.

How is the module configured?

The module address and input channel configurations are set manually using the DIL switches located on the unit.
