FUNCTIONAL DESCRIPTION:

IS200TRLYH1DAC is a Simplex Contact Output Terminal Board manufactured and designed by General Electric as part of the Mark VIe Series used in GE Distributed Control Systems. The TRLYH1D terminal board features 12 plug-in magnetic relays. The first six relays can be configured with jumpers for either dry Form-C contact outputs or for controlling external solenoids. Field solenoid power can be supplied by a standard 125 V DC or 115/230 V AC source, or optionally, a 24 V DC source with jumper-selectable fuses and integrated suppression. The next five relays (7-11) provide unpowered isolated Form-C contacts, while Relay 12 is also an isolated Form-C contact designated for specific uses, such as ignition transformers. In Mark VIe systems, the TRLY board is operated by the VCCC or VCRC board, with molded-plug cables connecting the terminal board to the VME rack housing the I/O boards. Both Simplex and TMR configurations are supported, with plug JA1 used in Simplex systems, and JR1, JS1, and JT1 plugs used in TMR systems.

INSTALLATION:

The 12 relay outputs connect directly to two I/O terminal blocks installed on the terminal board, as illustrated in the accompanying figure. Each block is secured with two screws and features 24 terminals that accommodate wires up to #12 AWG.

A shield terminal strip, grounded to the chassis, is located on the left side of each terminal block. Typically, solenoid power for outputs 1-6 connects via JF1, while JF2 enables power daisy-chaining to additional TRLY boards. Alternatively, when JF1/JF2 is not in use, customer-supplied power can be connected directly to TB3. JG1 supplies power to the customer’s designated solenoid for Output 12.

OPERATION:

• The relay terminal board includes relay drivers, fuses, and jumpers. In simplex setups, D-type connectors transmit control signals and monitor feedback voltages between the I/O processors and the TRLY board through JA1.

• Relays operate at the frame rate, with a 3.0 A capacity. Their contact-to-contact voltage rating is 500 V AC for one minute, and the coil-to-contact rating is 1,500 V AC for one minute. Typical relay activation time is 10 ms. For relays 1-6, a 250 V MOV is used for transient suppression between the normally open and power return terminals.

• The relay outputs incorporate failsafe measures: if a cable is disconnected or if communication with the associated I/O processor is interrupted, the inputs automatically signal to de-energize the corresponding relays.
