IS200TTURH1CCC S1DF00Z GE Mark VI Speedtronic Turbine Speed Sensor Interface Module
H2 Overview
IS200TTURH1CCC S1DF00Z Product Introduction
IS200TTURH1CCC (Code S1DF00Z) is a dual-channel magnetic reluctance speed sensor interface module manufactured by GE for the Speedtronic Mark VI turbine control system. This board converts raw sine-wave signals from magnetic pickup (MPU) speed probes into TTL square pulses, so the Mark VI main controller can calculate real-time rotational speed, phase angle and overspeed protection values for gas turbines, steam turbines and compressors.
It adopts fully redundant dual independent input channels with cross-channel deviation check. If signal difference exceeds threshold, the module triggers alarm to prevent false trip. It is a safety-critical board for turbine overspeed protection (OSP), zero-speed monitoring during barring gear operation and generator frequency synchronization. The board has built-in signal conditioning, noise filtering and comprehensive self-diagnostics for power plant heavy-duty environments.
H2 Key Features
- ✅ Dual fully redundant input channels (CH A & CH B) for speed pickup signals
- ✅ Supports passive / active magnetic pickup (MPU) sensors and proximity switches
- ✅ Signal conditioning: converts sine wave to TTL square wave pulse
- ✅ Cross-channel comparison & deviation alarm function
- ✅ On-board self-diagnosis for sensor fault, cable break and signal abnormality
- ✅ Designed for GE Speedtronic Mark VI turbine control rack
- ✅ High noise immunity for power plant strong electromagnetic interference
- ✅ Part Number: IS200TTURH1CCC | Code: S1DF00Z
