ABB IMHSS05 Bailey Hydraulic Servo Slave Module

Description

The ABB IMHSS05 is a high-performance control module for Bailey Infi 90 and Network 90 systems, designed to manage hydraulic servo actuators in steam turbine speed control and valve positioning. It processes feedback from LVDTs or potentiometers and generates precise current outputs to drive servo valves. By offloading high-speed tasks from the main controller, it ensures real-time, deterministic response for critical mechanical regulation in power generation and heavy industry.
