TRLY_1B is controlled by the VCCC, VCRC, or VGEN board and supports simplex and TMR applications. Cables with molded plugs connect the terminal board to the VME rack where the I/O boards are mounted. Connector JA1 is used on simplex systems,and connectors JR1, JS1, and JT1 are used for TMR systems.

Product Installation---Simplex:
Relay drivers, fuses, and jumpers are mounted on the TRLY_1B. For simplex operation,D-type connectors carry control signals and monitor feedback voltages between the I/O processor and TRLY_1B through JA1.
Relays are driven at the frame rate and have a 3.0 A ac rating. The typical time to operate is 10 ms. Relays 1-6 have a 250 V metal oxide varistor (MOV) for transient suppression between Normally Open (NO) and the power return terminals. The relay outputs have a fail-safe feature that vote to de-energize the corresponding relay when a cable is unplugged or communication with the associated I/O processor is lost.
Product Installation---TMR:
For TMR applications, relay control signals are fanned into TRLY_1B from the three I/O processors R, S, and T through plugs JR1, JS1, and JT1. These signals are voted and the result controls the corresponding relay driver. Power for the relay coils comes from all three I/O processors and is diode-shared. The following figure displays a TRLY_1B in a TMR system.
