Versatile I/O Control for Mark V Turbine Systems
This I/O control card manages digital and analog signals for GE Mark V turbine controls. The GE DS200SIOBH1A interfaces between field devices and the main processor. The DS200SIOBH1ABA variant offers identical functionality for direct drop-in replacement. Multiple I/O channels support both input and output signal types. Consequently, this card handles turbine status monitoring and actuator control tasks.
I/O Configuration & Signal Specifications
The GE DS200SIOBH1A DS200SIOBH1ABA accepts 24V DC inputs from field sensors and limit switches. It provides relay outputs for controlling valves, contactors, and indicator lights. Each output channel includes built‑in surge suppression for inductive loads. Four status LEDs indicate power, communication, and I/O activity clearly. Therefore, this control card delivers reliable signal processing for demanding power generation applications.

Installation & Field Wiring
You insert the GE DS200SIOBH1A DS200SIOBH1ABA into a standard Mark V rack slot. The 64-pin DIN connector mates directly with the backplane for signal routing. Connect your field sensors to the input terminals on the front panel. Wire your actuators to the output terminals using appropriate gauge wire. Consequently, the card processes all I/O signals without additional external conditioners.
Operational Advantages & System Integration
The GE DS200SIOBH1A DS200SIOBH1ABA combines multiple signal types in a single card. This integrated design saves valuable rack space for other control components. Four status LEDs allow immediate visual verification of card operation. A green RUN LED confirms normal communication with the main processor. Therefore, this I/O control card provides comprehensive signal management for Mark V turbine systems.
