I/O modules

The DS200DCFBG1B DS200DCFBG1BEB provides reliable DC power conversion for Mark V turbine control systems. This board converts 250V DC input into stable 24V DC output. It also supports a 120W continuous power rating for industrial applications.

Key Technical Specifications

Physical Layout and Components

This board measures 25.4 cm in length and 18.0 cm in width. Its height stands at 5.1 cm including the heat sink. DS200DCFBG1B DS200DCFBG1BEB weighs exactly 2.3 kg for robust mechanical stability. You will find 78 discrete components soldered on a four-layer PCB.

Moreover, the board includes a 6800 µF bulk capacitor bank for energy storage. This bank smooths voltage ripples during load transients. It also holds enough charge for a 50 ms hold-up time after input loss.

Connectors and Interfaces

The front panel provides two 20-pin male connectors. These connectors accept field wiring harnesses for input and output power. A separate 8-pin auxiliary interface carries status signals to the main controller. Furthermore, a grounding stud sits near the bottom edge for safety connections.

Thermal and Mechanical Design

A passive heat sink covers eight power transistors on the board. This design removes heat without active cooling fans. Consequently, the board operates silently in dusty industrial cabinets. The single-slot VME carrier ensures easy installation into existing racks.

Reliability and Use Cases

You can deploy DS200DCFBG1B DS200DCFBG1BEB in gas turbine, steam turbine, and exciter control panels. This board delivers clean 24V DC power to I/O modules and field devices. Its high capacitance also protects downstream circuits from brief power interruptions.
