Core Functions and Typical Applications

I/O Wiring Hub

Serves as the central field wiring interface for 4–20 mA analog and digital I/O signals.

Transfers conditioned signals between field devices and the drive control card.

Power Distribution

Distributes regulated (+5 V / +15 V) and unregulated (±24 V) power to onboard circuitry and connected field sensors.

Configuration and Troubleshooting

Allows I/O function customization via jumper settings.

RS-232 interface supports system setup, diagnostics, and maintenance.

Typical Applications

GE Mark V gas and steam turbine drive systems.

Commonly used with:

DS200SDCCG4AFD (Drive Control Card)

DS200SIOBH1ABA (Analog I/O Board)

Applied in fuel control, speed regulation, and actuator drive signal conversion.
