Description
ABB 07DC91C GJR5251400R0202 AC31 Digital I/O Module
Product Overview
07DC91C, part number GJR5251400R0202, is a distributed digital I/O slave module for the ABB Advant Controller 31 (AC31) automation system. It communicates with the main controller over the CS31 fieldbus and collects discrete signals from field sensors, while sending switching commands to actuators. Furthermore, this module runs on 24VDC and combines fixed inputs, transistor outputs and flexible configurable channels in one compact unit. It supplies reliable replacement hardware for aging ABB AC31 distributed control cabinets.
Key Features
- It works as a CS31 bus slave for ABB AC31 distributed control system
- Moreover, channel allocation: 16 digital inputs, 8 transistor outputs, 8 configurable I/O
- It uses 24VDC supply, each output channel supports up to 0.5A load current
- In addition, it provides reverse polarity protection for the power supply terminal
- It carries multiple LED indicators to display channel status and diagnostic alarms
- It adopts standard DIN rail mounting for quick installation inside control cabinets
- It meets IP20 protection rating and fits factory, power and water process control
Applications
Specifically, this I/O module expands remote signal points for ABB AC31 systems in power plants, water treatment and general manufacturing lines. Maintenance technicians use it to restore field discrete signal loops.
