The IMFCS01 is a high-precision Frequency Counter Slave Module for the ABB Bailey Infi 90 Control System and Symphony Plus automation architectures. It is designed for turbine speed and rotational monitoring, measuring high-speed pulse signals from magnetic pickups (MPUs) or tachometers to support governor control and overspeed protection logic.
As a slave module, the IMFCS01 communicates with a master controller (such as IMHSS03 or BRC series CPUs) via the internal Slave Bus, ensuring fast and deterministic transfer of speed data with minimal processing load on the main controller.

How does the module communicate with the controller?
It transmits frequency data through the Slave Bus, allowing the master CPU to read speed information without performing high-speed pulse counting.
Can it be used for position sensing?
It is primarily designed for rotational speed measurement, but may support pulse-based position sensing if the sensor output is frequency proportional to movement.
