GE IS200DRLYH1A IS200DRLYH1AAA Mark VI Simplex Relay Output Board

The GE IS200DRLYH1A board provides discrete relay outputs for the Mark VI system. This simplex relay output board also carries the revision code IS200DRLYH1AAA . It switches high-current loads for auxiliary equipment control. The board activates solenoids, contactors, and indicator lamps reliably.

Technical Specifications of GE IS200DRLYH1A IS200DRLYH1AAA

Component Count and Board Construction

This GE IS200DRLYH1A board contains sixteen individual electromechanical relays. Each relay features silver alloy contacts for long switching life. Furthermore, the board includes flyback diodes for inductive load protection. You will also find LED indicators for each relay channel.

Interfaces, Energy Storage, and Signal Paths

The IS200DRLYH1AAA revision provides screw terminal blocks for field wiring. Moreover, the board stores minimal energy due to its relay-based design. It uses small capacitors only for contact debouncing purposes. Consequently, this output board does not require large energy storage devices.

Functional Logic and Application Context

This Mark VI board receives command signals from the main controller. It then energizes or de-energizes the output relays accordingly. The GE IS200DRLYH1A supports both normally open and normally closed configurations. Additionally, it monitors each relay coil for open circuit conditions. Consequently, the board reports coil failures back to the controller immediately.

Installation and Environmental Limits

You must isolate the 24 V DC supply before removing this relay board. The operating temperature range spans -30°C to +65°C . Furthermore, the board withstands 5 g vibration without contact chatter. Always verify the IS200DRLYH1AAA wiring against the terminal diagram before power-up.
