I/O modules

The DS200DCFBG1B DS200DCFBG1AGB converts 250V DC input into regulated 24V DC output. This board provides 120W of continuous power for Mark V systems. It operates reliably across a wide temperature range.

Key Technical Specifications

Physical Dimensions and Component Layout

This board measures 25.4 cm in length and 18.0 cm in width. Its total height reaches 5.1 cm including the heat sink. DS200DCFBG1B DS200DCFBG1AGB weighs exactly 2.3 kg for mechanical stability. You will find 78 discrete components soldered on a four-layer PCB.

Furthermore, the board includes a 6800 µF bulk capacitor bank for energy storage. This bank smooths voltage ripples during sudden load changes. It also provides a 50 ms hold-up time after losing input power.

Connector and Interface Details

The front panel offers two 20-pin male connectors for field wiring. These connectors separately handle the input and output power paths. An 8-pin auxiliary interface carries diagnostic status signals to the controller. A grounding stud also sits near the bottom edge for safety connections.

Thermal Management Approach

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

Typical Application Scenarios

You can deploy DS200DCFBG1B DS200DCFBG1AGB in gas turbine control panels. It also works well in steam turbine and excitation systems. This board delivers clean 24V DC power to field I/O modules. Its high capacitance protects downstream circuits from brief power interruptions.
