IS200TTURH1BCC Primary Protection Input Board
Product Overview
The IS200TTURH1BCC is a primary protection input board from General Electric for the Mark VI Speedtronic series. This turbine termination board (TTUR) manages essential I/O for generator synchronization, speed sensing, and voltage monitoring. It provides 125 V DC output for the main breaker coil (52G). It supports both Simplex and TMR systems for reliable turbine control. This board uses surface mount technology for compact industrial design.

Key Features & Diagnostics
- Speed Sensing: 12 passive MPU inputs for turbine speed (2 Hz – 20 kHz, 0.05% accuracy).
- Generator & Bus Voltage: Dual PT inputs (115 V rms) with 1,500V isolation.
- Relay Drivers: Three relays (K25, K25P, K25A) for 52G breaker closure.
- Shaft Monitoring: Processes voltage and current from shaft sensors.
- Jumper Config: JP1/JP2 select Simplex or TMR (Triple Modular Redundancy).
- Diagnostic Capability: Onboard monitoring of MPU pulse integrity and relay status.
- EMI Protection: Shielded terminals and conformal coating enhance noise immunity.
- Cable Length: Supports PT wiring up to 1,000 ft (18 AWG).
Installation & Wiring Guide
- Connectors: Use JR5 for speed signals; JR1 for other I/O. TMR uses JR5, JS5, JT5, JR1, JS1, JT1.
- Terminal Blocks: TB1 and TB2 accept up to #12 AWG. Each has a shield ground strip.
- Jumper Settings: Set JP1/JP2 for Simplex or TMR mode before installation.
- Optional TTL: TB3 supports external power for active speed pickups.
- Grounding: Use chassis ground on shield strips to reduce interference.
- PT Wiring: Keep twisted pairs and maintain isolation for 115 V rms inputs.
- Coil Output: 125 V dc to breaker coil – verify polarity and current rating.
