Product Introduction

The ABB 07AC91B GJR5252300R0101 is an analog I/O module for ABB Advant Controller 31 (AC31) PLC system, working as remote I/O via CS31 field bus. It supports 16 configurable analog channels (8AI /8AO), 12-bit resolution with sign, compatible with voltage and current signals like 0-10V, ±10V, 0/4-20mA. Powered by 24VDC, it provides galvanic isolation for CS31 bus interface. It collects analog signals from transmitters and outputs control signals to field actuators, widely used in chemical, power, pulp & paper industrial automation control systems.

Content Details

ABB 07AC91B is high density analog remote I/O unit for AC31 system. Users configure each channel as analog input or analog output through module coding switches. It transmits field analog data to main controller and receives output commands over CS31 bus. Built-in hardware diagnostics detect channel fault, short circuit and power abnormality, sending alarm messages to PLC. It adopts DIN rail mounting and removable screw terminals for convenient wiring and on-site replacement. With compact rugged housing and 0~55°C operating temperature range, this module can run stably under industrial vibration and electromagnetic interference. 07AC91B GJR5252300R0101 is used for spare replacement and system upgrade of ABB AC31 PLC. Before shipment, each unit undergoes full functional test and thermal aging inspection to eliminate hidden defects and guarantee reliable long-term continuous operation.
