GE IS200TBCIH2CCD Contact Input Terminal Board

GE IS200TBCIH2CCD Contact Input Terminal Board

The GE IS200TBCIH2CCD, also cataloged as the IS200TBCIH2C contact input terminal board, serves as the primary interface for 24 dry contact signals within the Speedtronic Mark VI turbine control system.

Hardware Specifications

Profinet / EtherNet/IP Deterministic Networks

The IS200TBCIH2CCD integrates into Mark VI deterministic scan cycles. Contact input signals are routed through optical isolation and noise suppression circuitry, ensuring predictable timing and stable propagation delay across all 24 channels. I/O density scaling is preserved in simplex or TMR configurations, while firmware flash compatibility in associated controllers maintains synchronization integrity.

Frequently Asked Questions

Q: What type of filtering is used on the contact inputs? A: Hardware filtering with a 4 ms response time suppresses noise and interference, ensuring clean input signals.

Q: How is redundancy achieved in TMR configurations? A: In TMR systems, connectors JR1, JS1, and JT1 are all utilized to provide triple modular redundancy for contact input signals.

Q: What happens if excitation voltage is lost? A: The system detects loss of excitation voltage and generates an alarm, preventing undefined input states.

Field Installation Guidelines

• Mount securely on DIN rail or panel assemblies with proper retention.
• Route contact input wiring separately from high‑voltage conductors.
• Ensure shield terminal strips are bonded to chassis ground to minimize EMI.
• Maintain clearance for airflow and thermal dissipation.
• Verify connector seating for JR1, JS1, and JT1 in redundant configurations.
• Inspect terminal block screws for proper torque to prevent intermittent connections.
