GE DS200MBHAG1A DS200MBHAG1AFC stores energy using one electrolytic capacitor. This capacitor provides 47 µF at 35V rating for transient filtering. Consequently, the board maintains communication during 15 millisecond power interruptions. Therefore, data packets remain intact through brief voltage sags.
Design and Integration
Both the GE DS200MBHAG1A and DS200MBHAG1AFC versions share identical serial communication circuitry. These boards use four-layer PCB construction with isolated RS-485 lines for noise immunity. Consequently, the GE DS200MBHAG1A DS200MBHAG1AFC 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 RS-485 port supports cable runs up to 1200 meters. We recommend using shielded twisted-pair cables for all serial connections.
Practical Application
This communication board connects turbine controls to plant DCS systems and HMIs. It translates data between multiple serial protocols for seamless integration. The GE DS200MBHAG1A DS200MBHAG1AFC also performs error checking and diagnostics. Therefore, it enables reliable data exchange in GE industrial control systems.
