Product function

GE IS200TICIH2A Contact Input Terminal Board Provides isolated, noise-suppressed detection of up to 24 contact closures (e.g., relay contacts, limit switches) for GE Mark VIe/VIeS control systems. Interfaces directly to an I/O pack via the on-board D-sub connector, translating field signals into the IONet Ethernet network for turbine control logic.

Core supporting modules

I/O Packs: IS230TAI*/IS230TICI* series analog and contact‐input packs

Controllers: GE Mark VIe CPU modules (e.g., IS200TPROH1C family)

Other Terminal Boards: Complementary analog, relay‐output, thermocouple, and RTD input boards

Extension components

DIN-Rail Mounting Kit: Optional angle brackets for standard 35 mm rail

Sheet-Metal Carrier: Insulator and mounting plate for cabinet installation

Pluggable Terminal Blocks: Field‐wiring blocks (screw‐clamp type) that plug onto the board header

Shielding Accessories: Separate clamp for shield termination when using shielded cables

Software support

Configuration: None required—fully passive hardware

Monitoring: Integrated self-test on power-up; status reported by controller diagnostics

Firmware: Not applicable

Integration: Transparent to GE ControlST™ (ToolboxST™) and Mark VIeS system software

Documentation: Covered in GE Mark VIe/VIeS System Manuals and I/O Installation Guide
