Main Functions

Provides relay output termination for compatible GE Mark VI turbine control systems.
Provides 12 relay outputs for switching external control circuits.
Uses higher-powered relay contacts compared with the related DRLYH1B configuration.
Connects to the VCRC I/O processor through a 37-pin cable interface.
Designed specifically for simplex applications rather than TMR operation.
Uses wall mounting rather than the DIN-rail mounting used by some other Mark VI terminal boards.
Suitable for maintenance replacement and spare-parts inventory when the complete part number and system configuration match.

Q&A

Q: What is the exact part number?
A: The base model is IS2020DRLYH1A, with the full assembly reference IS2020DRLYH1AA.

Q: What type of board is this?
A: It is a Relay Output Terminal Board in the GE Mark VI control system.

Q: How many relay outputs are provided?
A: The H1AA configuration provides 12 relay outputs.

Q: Is this board designed for TMR operation?
A: No. Technical references identify the H1AA version as a simplex relay-output board.

Q: How does it connect to the control system?
A: The DRLY board connects to the associated VCRC I/O processor through a 37-pin cable connector.

Q: Is this a card-cage processor board?
A: No. Despite some marketplace listings describing it as a “card cage” or “card assembly,” the technical function is a wall-mounted relay output terminal board.

Q: Can IS2020DRLYH1AA replace an H1BA or H1B version?
A: Not automatically. Verify the relay-contact configuration, mounting arrangement, redundancy requirement, complete part number, and installed Mark VI system before substitution.
