General Electric IS200TBCIH1BCE Mark VI Contact Terminal Board

GE IS200TBCIH1BCE Contact Input Terminal Board

The GE IS200TBCIH1BCE, also cataloged as the IS200TBCIH1BCE contact input terminal board, serves as the primary TBCI module used to execute 24‑point dry‑contact signal termination and group‑isolated input routing across Mark VI Speedtronic platforms.

Hardware Specifications

Profinet / EtherNet/IP Deterministic Networks

As part of GE’s Mark VI control architecture, the IS200TBCIH1BCE aligns with deterministic I/O acquisition cycles governed by the controller’s scheduling window. The board’s group‑isolated contact inputs maintain stable propagation delay across simplex and TMR paths when paired with VCCC/VCRC processors. Firmware flash compatibility resides entirely in the I/O processor; the TBCI board contains no programmable logic. I/O density scaling is achieved through fixed hardware design, including MOV arrays, resistor banks, and capacitors arranged for surge suppression and high‑frequency noise reduction.

Frequently Asked Questions

Q: Does the IS200TBCIH1BCE support hot‑swap replacement? A: No. The board must be replaced only with cabinet power isolated to avoid undefined contact‑state transitions.

Q: Are there any jumpers or configurable hardware on the board? A: No. The board is fully fixed‑configuration and relies on upstream excitation voltage and processor thresholds.

Q: How many terminals are available for wiring? A: Two barrier‑type terminal blocks provide 48 terminals supporting 24 contact input channels.

Field Installation Guidelines

• Maintain proper polarity and wiring discipline on all 24 contact inputs.
• Terminate shields to chassis ground to minimize surge and high‑frequency interference.
• Ensure barrier‑type terminal blocks are fully seated before energizing the system.
• Keep contact wiring isolated from high‑energy conductors to reduce induced noise.
• Verify correct seating of all board‑edge connectors to maintain stable processor communication.
• Follow GE installation manuals for torque values, grounding, and cabinet layout requirements.
