Key Technical Specifications

This GE IS200WROGH1A IS200WROGH1APR1 board operates at 250V AC or DC input voltage. It handles 10A continuous current for time delay switching applications. The unit measures 12 cm in length, 8 cm in width, and 2.5 cm in height. Its total weight equals 0.35 kg without any packaging.

The GE IS200WROGH1A IS200WROGH1APR1 includes four electromechanical relays for output switching. Additionally, it features one DIP switch array for delay configuration. A single 10-pin header connects to the main control board. The board contains 4 relays, 2 timing ICs, 6 diodes, and 12 resistors.

GE IS200WROGH1A IS200WROGH1APR1 stores energy using one high-voltage capacitor. This capacitor provides 100 µF at 450V rating for relay coil hold-up. Consequently, the board maintains output contact closure during short power loss.

Design and Integration

Both the GE IS200WROGH1A and GE IS200WROGH1APR1 versions share identical delay circuitry. These boards use two-layer PCB construction with 2 oz copper for high current paths. Therefore, the GE IS200WROGH1A IS200WROGH1APR1 operates reliably from -10°C to +55°C ambient temperature.

For installation, you plug the board directly into a compatible main board header. The daughter board draws 50 mA typical current from the 250V supply. During relay switching, it briefly consumes 200 mA for about 20 milliseconds. We recommend using a 12A slow-blow fuse for circuit protection.

Practical Application

This time delay board creates programmable off-delay or on-delay functions for industrial controls. It delays motor starter dropout or conveyor sequencing in automation systems. The GE IS200WROGH1A IS200WROGH1APR1 also provides four independent timing channels. Therefore, you can set each relay with different delay values from 0.1 to 60 seconds.
