Thermocouple Signal Processing and Mark VI Interface

The IS200TPROH1C provides multi-channel thermocouple termination and signal conditioning for GE Mark VI control architectures. The board accepts low-level thermocouple millivolt signals and transfers processed temperature information through the associated I/O pack interface.

The integrated cold junction compensation function maintains temperature measurement accuracy by compensating for terminal reference temperature variations. The input design supports thermocouple fault monitoring functions including open-circuit and short-circuit detection.

For Mark VI system integration, the terminal board connects with compatible I/O packs such as PTCC modules and exchanges control data through the VME-based controller architecture.

Frequently Asked Questions

Q: What thermocouple inputs are supported by the IS200TPROH1C?

Q: Does the IS200TPROH1C provide cold junction compensation?
A: Yes. The board includes integrated cold junction compensation for thermocouple reference temperature correction.

Q: What power supply is required for the IS200TPROH1C?
A: The terminal board operates with a 24 VDC supply within the Mark VI control system cabinet configuration.

Field Installation Guidelines

Install the IS200TPROH1C in the designated GE Mark VI cabinet slot location and verify mechanical alignment before securing the board connections.

Use shielded thermocouple wiring with appropriate grounding practices to reduce electrical interference on low-level millivolt signals. Keep thermocouple cables separated from high-current power wiring, motor cables, and switching circuits.

Confirm that the thermocouple type configuration matches the connected field sensors before commissioning. Check terminal connections, sensor polarity, and cable continuity during installation and maintenance procedures.

Follow GE Mark VI cabinet grounding, shielding, and I/O wiring documentation for final field termination and system integration.
