IS2020DRLYH1A is a Simplex Relay Output Terminal Board manufactured and designed by General Electric as part of the Mark VIe Series used in GE Distributed Turbine Control Systems. The Simplex Relay Output (DRLY) terminal board is a compact relay output terminal board designed for wall mounting (not DIN-rail mounting). The board has 12 form-C dry contact output relays and connects to the VCCC, VCRC, or VTUR processor board with a single cable. The 37-pin cable connector is identical to those used on the larger TRLY terminal board. Two DRLY boards can be connected to VCCC, VCRC, or VTUR for a total of 24 contact outputs. Only a simplex version of this board is available.


Mount the DRLY board by fastening screws to the wall through the four mounting holes in the corners of the metal support plate. Connect the wires for the 12 relay outputs directly to the odd-numbered screws on the terminal blocks. The high-density Euro-block type terminal blocks plug into the numbered receptacles on the board. The two screws on TB2 are provided for the SCOM (chassis ground) connection, which should be as short a distance as possible.


DRLY does not include solenoid source power. There is one set of dry contacts per relay, with two NO contacts in series. Unlike TRLY, there is no on-board suppression and no relay state monitoring. The I/O board (VCCC, VCRC, or VTUR) provides the 28 V DC power for the relay coils, which is indicated with a green LED. DRLY has a yellow LED for each relay that indicates voltage across the coil. With an unconnected control cable, the relays default to a de-energized state.
