I/O modules

This simplex relay output board provides dependable switching for industrial control applications. The GE IS200DRLYH1A IS200DRLYH1AAA features twelve independent electromechanical relays on a single board. Each relay supports both normally open and normally closed contact configurations. Consequently, operators can control actuators, solenoids, or alarm circuits with confidence.

Technical Specifications of the Relay Output Board

The GE IS200DRLYH1A IS200DRLYH1AAA fits a standard VME form factor seamlessly. Its height measures 233.4 mm, and its depth reaches 160 mm. The board weighs approximately 0.7 kg for straightforward handling. A single front panel LED array shows each relay’s energized state at a glance. The rear side uses a 64-pin DIN 41612 connector for all signal and power connections. This design stores no batteries or large capacitors. Instead, it relies on passive suppression components for contact protection.

Functional Features and Installation

The GE IS200DRLYH1A IS200DRLYH1AAA provides optically isolated coil drivers for each relay. This isolation prevents electrical noise from disturbing the backplane signals. You can replace any faulty relay on the board individually. Accordingly, maintenance costs remain lower than replacing the entire assembly. Each relay also includes a manual override button for testing purposes.

You must install this board into any standard VME backplane chassis. The board does not include field wiring terminals directly. Instead, pair it with a compatible termination panel like the IS200TDRYH1B. Always verify backplane slot compatibility before installation.

Safety and Operational Benefits

Because the GE IS200DRLYH1A IS200DRLYH1AAA stores no onboard energy, it supports safe hot-swapping. Technicians can replace the board without powering down the entire rack. This feature reduces system downtime significantly. The board also reports coil faults to the Mark VIe controller instantly. Therefore, operators receive immediate alerts for relay failures.
