ABB IMSER02 Digital Exchange Repeater Module

Product Description

The ABB IMSER02 Digital Exchange Repeater is a communication interface module developed for the Bailey INFI 90 Distributed Control System. It is designed to regenerate and relay digital network signals across the system communication bus, ensuring stable data transmission between distributed control modules.

Within large or geographically extended DCS installations, signal attenuation can occur due to cable length or network load. The IMSER02 repeater module restores signal strength and timing integrity by amplifying and retransmitting the digital exchange signals. This process helps maintain reliable communication between controllers, interface modules, and field I/O devices.

The IMSER02 module integrates directly into the INFI 90 system rack and receives operating power through the system backplane. Built with industrial-grade components, it supports continuous operation in process control environments where communication reliability is critical.
