GE Mark VI Relay Interface
The IS200TRLYH1BGF provides relay contacts for discrete output functions within the GE Mark VI architecture. Its 12 Form C relays provide changeover contacts for external control circuits. Therefore, the connected field circuit must remain within the specified contact voltage and current ratings.
The board uses 24 VDC board logic and provides 1500 VAC isolation as specified. In addition, the stated operate/release time is 10-15 ms typical, while initial contact resistance remains below 100 mOhm.
The supplied data identifies one special unfused configuration. Consequently, external circuit protection must follow the associated Mark VI control cabinet and field wiring design rather than assuming integral fuse protection.
Frequently Asked Questions
Q: How many relay outputs does the IS200TRLYH1BGF provide?
A: The board provides 12 Form C relays for discrete relay output switching.
Q: What contact loads can the relay outputs handle?
A: The supplied specifications list 24 VDC at 3 A, 125 VDC at 6 A, and 120/240 VAC at 3 A.
Q: What are the specified operating and storage temperatures?
A: Operating temperature is -30 deg C to +65 deg C. Storage temperature is -40 deg C to +85 deg C.
Field Installation Guidelines
- Verify the complete IS200TRLYH1BGF model designation before installation.
- Confirm that every connected field circuit remains within the specified relay voltage and current ratings.
- Follow the Mark VI cabinet wiring documentation for terminal assignment and circuit routing.
- Keep relay output wiring separated from low-level analog or communication wiring where the cabinet design requires segregation.
- Connect protective earth and cabinet grounding according to the system installation documentation.
- Do not assume the special unfused configuration provides external circuit protection.
- Inspect relay terminals and connectors for mechanical damage before energizing the circuit.
- Verify field wiring continuity and polarity where applicable before applying control power.
- Confirm relay operation through the approved Mark VI commissioning procedure.
