Overview

The ABB 87TS01-1551 PCB Board, also known by its ordering code GJR2368900R1551, is a critical component within ABB’s Advant OCS and MOD 300 control system family. It functions as a coupling module, ensuring stable signal transmission and electrical isolation between different parts of the control architecture. Moreover, it is engineered to withstand harsh industrial conditions, including electromagnetic interference, temperature fluctuations, and mechanical stress.

This module plays a vital role in protecting control units from overvoltage, surges, and mismatched ground potentials. In addition, its plug-in design and clearly marked terminals allow seamless integration into existing racks, reducing installation time and maintenance complexity. Therefore, it is widely adopted in industries requiring high reliability and long-term system stability.

Technical Data

Typical Applications

• Distributed control systems (DCS) in chemical, petrochemical, and power generation plants.

• Industrial automation requiring stable signal transmission across multiple subsystems.

• Process control environments with high electromagnetic interference, where isolation ensures signal integrity.

• Boiler and turbine control systems needing reliable communication between sensors and controllers.

• OEM integration for legacy ABB Advant MOD 300 systems still in operation worldwide.

For instance, in a refinery automation system, the 87TS01-1551 coupling module ensures that critical process signals are transmitted without distortion, protecting controllers from electrical surges and maintaining plant safety.
