Product Description

The ABB IMHSS03 is a professional hydraulic servo control module belonging to the ABB Bailey INFI90 Symphony DCS system. It acts as a core signal interface and closed-loop control unit between the main multifunction processor and field hydraulic servo valves. The module precisely collects hydraulic loop feedback signals and outputs high-resolution servo drive commands to achieve accurate turbine speed regulation and valve position closed-loop control for thermal power and process industrial equipment.

Designed for turbine hydraulic control loops, this module supports standard 24VDC wide-voltage power supply and high-precision analog signal interaction. It features built-in loop self-diagnosis, servo deviation correction and overcurrent protection functions, complying with SIL3 industrial safety certification. Adopting industrial reinforced design with strong anti-vibration and anti-interference performance, it supports 24/7 long-term stable hydraulic servo operation for power generation and heavy industrial control systems.
