Bailey IMFCS01 ABB Frequency Counter Slave

Description

The Bailey IMFCS01 Frequency Counter Slave Module is a single-channel frequency input designed for use with the Multi-Function Processor (MFP), Multi-Function Controller (MFC), and Hydraulic Servo Slave (HSS) modules. It connects steam or gas turbines to the MFP or MFC, providing accurate frequency count and time period data. The module enables turbine speed calculations and speed control through the HSS.
