IS200TRTDH1CCC Turbine Terminal Board Module

IS200TRTDH1CCC Turbine Terminal Board Module
This is a bridging interface terminal board (Turbine Relay Terminal Board) in the GE Mark VI/Mark VIe Speedtronic turbine control system.

core positioning
Manufacturer GE (General Electric)
System Mark VI/Mark VIe Turbine Control System
Functional type bridging interface terminal board, used for physical connection and routing of turbine signals
Compatible configuration supports Simplex (single mode) and TMR (triple mode redundancy)

Main functions
Signal bridging: As an intermediate interface between turbine field equipment (sensors, actuators, trip coils, etc.) and main control boards (such as VTUR, PTUR), it completes the physical connection and routing distribution of signals.
Relay driver: onboard relay, used to control circuit breaker closing, tripping logic, etc., activated by ⅔ voting logic in TMR system.
Multi type signal support: can connect various on-site signals such as proximity sensors, current/voltage inputs, LVDT feedback, etc.

Typical boards used in conjunction
VTUR (Main Turbine Protection Board) core protection logic processing
PTUR (turbine primary trip board) primary trip function
TTUR/IS200TTURH1CCC turbine terminal board (similar product)
TREL trip relay interface board

Key technical parameters (refer to similar TTUR series)
Input voltage 24V DC
Working temperature -40 ℃~85 ℃
Installation method: 19 inch standard rack, connected to the motherboard through DC-37 pin connector
Protection level meets IP67 (industrial grade)
Internal components include transformers, relays, MOVs (metal oxide varistors), diodes, resistors, capacitors

Application scenarios
Gas turbine/steam turbine control system
Protection and Monitoring of Turbine Units in Power Plants
Large scale compressor drive system for petrochemical industry
