GE DS200LUVAG1A DS200LUVAG1AFD stores energy using one electrolytic capacitor. This capacitor provides 220 µF at 35V rating for bus driver hold-up. Consequently, the board maintains communication during 25 millisecond power interruptions. Therefore, Genius network data remains stable through short voltage dips.

Design and Integration

Both the GE DS200LUVAG1A and DS200LUVAG1AFD versions share identical Genius controller logic. These boards use four-layer PCB construction with isolated bus drivers for noise immunity. Consequently, the GE DS200LUVAG1A DS200LUVAG1AFD operates reliably from -10°C to +55°C ambient temperature.

For installation, you need M3 screws for the four mounting holes. The board draws 200 mA typical current from the 24V DC supply. The Genius bus supports cable runs up to 750 meters at 1 Mbps. We recommend using shielded twisted-pair cable for the Genius bus connection.

Practical Application

This controller board acts as a Genius I/O bus master or slave in GE control systems. It exchanges data with remote I/O blocks, drives, and operator interfaces. The GE DS200LUVAG1A DS200LUVAG1AFD also performs bus diagnostics and node health monitoring. Therefore, it enables distributed control architecture for turbine and generator applications.
