ALSTOM PIB101C 3BD91299-B Pulse Input Card

Product Description

ALSTOM PIB101C (Part No. 3BD91299‑B) is the Pulse Input Board for ALSTOM gas turbine and steam turbine control systems. PIB101C acquires pulse signals from speed probes and encoders, conditions and converts field pulse/frequency signals for the controller, realizing turbine speed measurement, zero-speed detection, closed-loop speed control and pre-processing for overspeed protection. The PCB has conformal coating and communicates via rack backplane bus. It supports multi-channel pulse acquisition and signal fault diagnosis. Widely used in legacy ALSTOM gas turbine control systems as critical MRO spare parts for power plant turbine controls.
