GE IS200TRLYH1BFD Relay Output Terminal Board

FAQ

Q1. What is the IS200TRLYH1BFD used for?
It is a relay output terminal board designed to provide conditioned relay outputs for solenoids, alarms, and other devices in GE Mark VI/VIe turbine control systems.

Q2. How many relay channels does the board support?
It supports 12 plug‑in magnetic relay channels for multiple output circuits.

Q3. What relay contact types are provided?
The board uses Form‑C (SPDT) relays for flexible output control configurations.

Q4. What voltage levels can the relays handle?
Relays can switch DC voltages (12 V, 24 V, 125 V) and AC voltages (115/230 VAC).

Q5. How does the board connect to the turbine control system?
It connects to the I/O pack via DC‑37 pin connectors (JA1 for simplex or JR1/JS1/JT1 for TMR).

Q6. Does the board support redundancy?
Yes — it supports simplex and Triple Modular Redundancy (TMR) configurations.

Q7. What environmental conditions can it operate in?
The board is designed for industrial temperatures from roughly –30 °C to +65 °C.

Q8. What happens if the board fails?
Failure can interrupt relay output signals to field devices, potentially affecting control of solenoids and alarms in turbine operations.
