Why Engineers Specify This Model
- Direct OEM Form-Factor: IS200TRLYH1BGE is a plug-compatible replacement for the TRLY terminal board position in Mark VI I/O racks — no rewiring, no reconfiguration of the control system project file.
- Isolated Relay Outputs: Each relay channel provides galvanic isolation between the control system logic and field-side protective circuits, preventing ground loops and protecting the controller from field transients.
- Trip-Rated Reliability: Designed to meet the response-time and contact-integrity requirements of turbine trip and ESD circuits where relay chatter or contact failure is not acceptable.
- Simplex & TMR Compatible: Supports both simplex and triple modular redundant (TMR) Mark VI architectures, making it applicable across a wide range of plant configurations.
- Long Field Service Life: GE’s Mark VI platform is designed for 20+ year operational lifecycles; the TRLY board is built to the same durability standard.
- Minimal Commissioning Overhead: Terminal labeling and wiring conventions follow GE Mark VI standard drawings, reducing installation time for experienced control system technicians.
