Product Description
Overview
GE IS220PPRFH1B is a Proximity Pulse Input Pack (PPRF) designed for the GE Mark VIe turbine control system. It interfaces with proximity probes and magnetic pickups to measure turbine shaft speed, rotor position, and other pulse-based signals. The module converts raw sensor inputs into conditioned digital data, enabling precise turbine speed monitoring, overspeed protection, and synchronization. Built for industrial-grade reliability, it is widely used in power generation, oil & gas, marine propulsion, and heavy industry requiring accurate speed measurement.
