Overview

The ABB PS862E is a Linear Isolated Amplifier Board designed for ABB’s Advant OCS and MOD 300 distributed control systems (DCS). Its primary function is to amplify analog signals while providing galvanic isolation, ensuring sensitive control electronics are protected from noise, ground loops, and voltage surges.

• Signal Integrity: By isolating input and output circuits, the PS862E ensures enhanced signal integrity, reducing the risk of interference and improving the reliability of process control systems.

• Rugged Design: It is built for continuous operation in harsh industrial environments, including high electrical interference and vibration.

• System Compatibility: The board integrates seamlessly with ABB’s Advant OCS and MOD 300 systems, offering a modular solution for analog signal conditioning.

Technical Data

Typical Applications

• Process automation systems requiring stable analog signal amplification and electrical isolation.

• Power generation plants where isolated amplifiers protect turbine and boiler control electronics from interference.

• Chemical and petrochemical industries needing robust isolation for hazardous environments.

• Heavy manufacturing where vibration and electrical noise demand durable signal conditioning solutions.

• OEM integration for ABB Advant MOD 300 systems requiring modular amplifier solutions.

For example, in a refinery automation system, the PS862E ensures that sensor signals are amplified and transmitted safely to controllers, preventing electrical interference and maintaining process stability and safety.
