IS200TRLYHIB

The IS200TRLYH1B is a Relay Output Terminal Board developed by GE under the Mark VIe series. There are 12 plug-in magnetic relays on the Relay Output with Coil Sensing (TRLY1B) terminal board. The first six relay circuits can be set up with jumpers to drive external solenoids or dry, Form-C contact outputs. For field solenoid power, a basic 125 V dc or 115/230 V ac source or an optional 24 V dc source with personal jumper-selectable fuses and onboard suppression can be offered. The next five relays (7–11) are isolated Form-C contacts that are not powered. An isolated Form-C contact is used on output 12 for specialized uses like ignition transformers.

IS200TRLYH1B COMPATIBILITY

Simplex and TMR applications are supported by the PDOA/YDOA I/O pack when using the TRLY 1B. The terminal board's DC-37 pin connections accept the I/O pack as a plug-in. For simplex systems, connector JA1 is used, while for TMR systems, connectors JR1, JS1, and JT1 are used.

IS200TRLYH1B INSTALLATION

Wire the two I/O terminal blocks on the terminal board, TRLY1B Terminal Board Wiring, directly with the wires for the 12 relay outputs. Each block has 24 terminals that may accommodate wires up to #12 AWG and is secured with two screws. Each terminal block has a shield terminal strip on the left side that is connected to chassis ground. The solenoid power for outputs 1-6 should be connected to JF1. Power can be daisy-chained to additional TRLYs using JF2. Alternatively, when JF1/JF2 are not in use, power can be connected directly to TB3.

Connect output 12 of the special solenoid to connector JG1 to provide electricity. The factory removes jumpers JP1-JP6 and ships them in a plastic bag. If a field solenoid needs electricity, reinstall the proper jumper. Check each loop's energization individually in accordance with best practices, and install the jumpers as necessary. Remove the fuses from isolated contact applications to make sure that the power bus is free of suppression leakage.
