I/O modules

This GE IS200TRPGH2B IS200TRPGH2BDE Primary Trip Terminal Board provides termination for critical turbine trip circuits. The board interfaces between protection relays and the emergency shutdown system. You will find this component in many GE Mark VI safety-critical applications. The IS200TRPGH2BDE variant includes a rugged conformal coating for harsh environments.

Technical Specifications

Trip Circuit and Safety Features

The GE IS200TRPGH2B IS200TRPGH2BDE Primary Trip Terminal Board routes critical trip signals directly to the safety system. Each input channel includes surge suppression for reliable operation. The board provides force-guided relay contacts for fail-safe operation. Furthermore, it includes status feedback for each relay’s contact position. Consequently, the system can verify trip circuit integrity continuously.

Installation and Connection Steps

Mount this GE IS200TRPGH2B IS200TRPGH2BDE Primary Trip Terminal Board in the lower section of any Mark VI cabinet. First, secure the board using four M6 mounting bolts at the corners. After that, connect trip sensor wiring to the terminal block following the printed labels. Then, attach the two ribbon cables to the corresponding trip controller board. Finally, verify each channel’s continuity before applying power to the system.

Energy Discharge and Safety Notice

This GE IS200TRPGH2B IS200TRPGH2BDE Primary Trip Terminal Board stores no significant energy. Therefore, you can handle it immediately after power removal. However, field wiring may carry hazardous voltages from external protection relays. Always disconnect external power before touching any terminal.

Status Indication and Diagnostics

Eight green LEDs indicate the active state of each trip input channel. Four yellow LEDs show the position of each safety relay output. A red LED illuminates when any channel detects a wiring fault. These indicators help technicians troubleshoot trip circuit issues without special tools.
