GE DS200ADPAG1A DS200ADPAG1ABB stores energy using one electrolytic capacitor. This capacitor provides 47 µF at 35V rating for bus driver hold-up. Consequently, the board maintains communication during 15 millisecond power interruptions. Therefore, Genius network data remains stable through short voltage dips.
Design and Integration
Both the GE DS200ADPAG1A and DS200ADPAG1ABB versions share identical Genius adapter logic. These boards use four-layer PCB construction with isolated bus drivers for noise immunity. Consequently, the GE DS200ADPAG1A DS200ADPAG1ABB operates reliably from -10°C to +55°C ambient temperature.
For installation, you need M3 screws for the four mounting holes. The board draws 120 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 Genius adapter board interfaces a host controller with Genius I/O networks. It exchanges data between the main processor and remote I/O blocks. The GE DS200ADPAG1A DS200ADPAG1ABB also performs bus diagnostics and error checking. Therefore, it enables distributed I/O architecture for GE turbine and drive systems.
