GE DS200ACNAG1ABB stores energy using one electrolytic capacitor. This capacitor provides 22 µF at 35V rating for transceiver hold-up. Consequently, the board maintains network connection during 10 millisecond power interruptions. Therefore, data packets remain intact through brief voltage dips.

Design and Integration

This board uses four-layer PCB construction with isolated coaxial interface for noise immunity. Consequently, the GE DS200ACNAG1ABB operates reliably from -10°C to +55°C ambient temperature.

For installation, you need M3 screws for the four mounting holes. The board draws 100 mA typical current from the 24V DC supply. The Arcnet network supports deterministic token-passing communication. We recommend using 93 ohm coaxial cable for all Arcnet connections.

Practical Application

This Arcnet communication board connects turbine and drive controls to legacy industrial networks. It transmits real-time data between multiple controllers in a deterministic manner. The GE DS200ACNAG1ABB also performs network initialization and node management. Therefore, it enables reliable distributed control for GE automation systems.
