I/O modules

The DS200ADGIH1A DS200ADGIH1AAA expands I/O capacity for Mark V turbine systems. This board connects auxiliary devices like sensors, valves, and status indicators. It bridges field signals to the main controller’s backplane.

Key Technical Specifications

Physical Dimensions and Component Layout

This board measures 8.5 cm in length and 16.0 cm in width. Its total height reaches 2.2 cm including all components. DS200ADGIH1A DS200ADGIH1AAA weighs just 0.75 kg for easy handling. You will find 124 discrete components on a four-layer PCB.

Additionally, the board integrates a 470 µF bulk capacitor for energy storage. This capacitor filters noise on the 24V supply rail effectively. It also provides a 5 ms hold-up time during momentary power drops.

Connector Interfaces and Signal Routing

The front panel provides two 20-pin headers for digital I/O connections. A separate 32-pin header links to the VME backplane for data exchange. Four LED indicators show input status, output activity, and board health. Two 4-pin auxiliary connectors supply external 24V power for field devices.

Digital Output Characteristics

Each output channel uses an open-collector transistor configuration. These outputs sink current from external loads connected to a positive supply. Each channel handles up to 500 mA continuously without overheating. Therefore, you can drive small relays, indicator LEDs, and solid-state contactors directly.

Typical Application Scenarios

You can deploy DS200ADGIH1A DS200ADGIH1AAA in gas turbine auxiliary control panels. It also works well for steam turbine lube oil systems and valve position monitoring. This board reads pushbuttons, selector switches, and proximity sensor signals. Its 16 outputs control annunciator lamps, horn drivers, and solenoid valves.
