IS200TRLYH1BGF

IS200TRLYH1BGF is a 12-channel relay output terminal board for GE Mark VI turbine control systems. It is used for safety interlocks, emergency trips, solenoid and ignition circuit driving, with electrical isolation and surge protection for high reliability.

Description

1. Basic Information

  • Model: IS200TRLYH1BGF

  • Brand: GE (General Electric, now Emerson Automation Solutions)

  • Type: Terminal Relay Output Board (TRLY Terminal Relay Card) for GE Speedtronic Mark VI Turbine Control Systems

  • Compatible Systems: Mark VI gas/steam turbine & combined‑cycle power plant control systems, supports Simplex & TMR (Triple Modular Redundant) architectures

2. Core Functions

Acts as an isolated relay output interface between the control system and field actuators, converting control signals into dry‑contact relay outputs to drive solenoids, circuit breakers, alarms, emergency trips, ignition transformers, etc. Features coil current monitoring, communication fault detection, fail‑safe de‑energization on loss of signal, and MOV surge suppression for channel‑level diagnostics and safety protection, ensuring high‑reliability operation.

  • Equipped with 12 plug‑in sealed electromagnetic relays: First 6 relays configurable via jumpers for Form‑C dry contacts or external solenoid drive; Relays 7–11 are passive isolated Form‑C contacts; Relay 12 is a dedicated contact for ignition transformer applications.

  • Supports multi‑power input: 24VDC, 125VDC, 115/230VAC, with individual jumper‑selectable fuses and electrical isolation (1500VAC coil‑to‑contact withstand).

3. Key Specifications

  • Number of Relays: 12 channels, contact rating 3A/250VAC, operating time ≤10ms

  • Isolation Voltage: 1500VAC (coil‑to‑contact), 500VAC (contact‑to‑contact)

  • Power Supply: 24VDC / 125VDC / 115–230VAC, jumper‑selectable, individually fused

  • Operating Temperature: -30°C to +65°C (standard), -40°C to +85°C (wide‑temp option)

  • Connections: 48 terminals (2×24), D‑type connectors (JA1 for Simplex, JR1/JS1/JT1 for TMR)

  • Protection: IP20, industrial‑grade EMC & vibration resistance

4. Applications

Widely used in gas/steam turbine control, power plant emergency shutdown (ESD), safety interlocks, valve/motor actuation, ignition control, oil & gas refining, and industrial process safety systems, serving as the safety output and actuator control interface for Mark VI control systems.
