GE IS200TPROH1C Proportional Output Terminal Board

The GE IS200TPROH1C, also cataloged as the IS200TPRO Emergency Protection Terminal Board, operates as a dedicated hardware component for field-side signal termination and analog conditioning within Mark VI and Mark VIe control system platforms.

Hardware Specifications

Firmware Flash Compatibility & Deterministic Networks

The IS200TPROH1C serves as the physical interface layer for proportional output control, providing direct electrical execution for valve positioning and actuator feedback. It supports integration with Mark VI/VIe deterministic networks, ensuring low-latency signal distribution from the I/O pack to the field devices. The hardware architecture maintains firmware flash compatibility with updated I/O packs, facilitating seamless system-wide performance upgrades. Furthermore, the board utilizes dedicated noise-filtering circuitry to ensure stable reference voltage generation during high-speed control cycles, maintaining precise loop performance regardless of backplane bus communication velocity.

Frequently Asked Questions

Q: Is the IS200TPROH1C capable of supporting redundant control configurations?

A: Yes, this terminal board is engineered to operate within both simplex and redundant Mark VI/VIe architectures. In a redundant configuration, the board maintains signal integrity across dual or triple modular controllers through isolation barriers that prevent fault propagation.

Q: What are the primary diagnostic capabilities of this terminal board?

A: The board performs continuous loop monitoring, including open-circuit and short-circuit detection. Fault states are transmitted back to the host I/O pack for processing, allowing the controller to trigger fail-safe state execution or maintenance alerts when output deviations occur.

Field Installation Guidelines

• Chassis Mounting: Install the board within the control panel using the designated rail mounts. Ensure the chassis provides a solid connection to the common ground plane to optimize surge protection effectiveness.
• Shielding Requirements: Connect all cable shields to the terminal board grounding studs. Use low-impedance paths to ensure that induced noise in the analog output loops is shunted away from sensitive control logic.
• Termination Torque: Tighten terminal block screws to the manufacturer-specified torque rating to prevent signal instability or intermittent resistance variations, which can compromise proportional accuracy.
• Loop Verification: Prior to energizing the system, verify that all external field power supplies are set to the correct voltage. Validate the output loop resistance against the I/O pack load requirements to ensure the circuit operates within its specified electrical limits.
