IS200TTURH1C GE Primary Turbine Protection Input Terminal board
Description：
IS200TTURH1C is designed as Primary Turbine Protection Input Terminal board manufactured by GE. It collects turbine speed, generator‑bus voltage, shaft voltage and current signals, and manages generator main‑breaker control for automatic synchronisation. IS200TTURH1C supports both simplex and TMR redundant configurations, delivering reliable signal acquisition and trip‑related interlock logic. IS200TTURH1C compatible with GE Mark VIe control I/O pack IS220PTUR all versions. 

Key Features:
▪ Handles up to 12 passive magnetic speed pick‑ups
▪ Provides 125 Vdc output to drive generator main breaker 52G
▪ Built‑in K25, K25P, K25A interlock relays
▪ Supports simplex and TMR redundant mode
▪ Convenience for field maintenance
▪ Diagnostic functions

Applications:
▪ Gas and steam turbine
▪ Power generation units
▪ Power plant

Expert Recommendation:
Always verify jumper settings to match your actual simplex or TMR hardware architecture before commissioning. Confirm terminal wire gauge and cable length comply with official specs to avoid measurement deviation or signal faults.

Q&A:
1. How to install IS200TTURH1C?
(1) Connect pulse rate pickups, shaft pickups, potential transformers and breaker relay to TB1 and TB2 terminal blocks.
(2) Fasten TB1 and TB2 each with two screws, terminals fit wires up to #12 AWG.
(3) Use chassis grounded shield terminal strips beside each terminal block for cable shielding.
(4) Set JP1 and JP2 jumpers to select simplex or TMR mode for K25, K25P relay drivers.
(5) Remove wire jumper WJ1 to isolate K25A control line connected to TRPX board as required.
(6) Link active speed pickups to optional TB3 TTL port; sensors need external power supply.
(7) Simplex system: adopt cable connectors PR3 and JR4.
(8) TMR system: utilise all six onboard cable connectors.
