GE IS220PDOAH1B Discrete Output Module

Technical Specifications

The IS220PDOAH1B is a discrete output I/O pack within the Mark VIe control system. The hardware provides the electrical interface between either a single or dual IONet local area network and a discrete output terminal board. Through this network-to-terminal interface, the unit receives serialized digital commands from the controller and routes the corresponding electronic signals to the terminal board relays for field device operation.

Board Compatibility and Relay Capabilities

The IS220PDOAH1B integrates a common BPPC processor board with a module-specific discrete output acquisition board, enabling compatibility with various discrete output terminal boards such as the TRLY and SRLY series. The module controls up to 12 relays and accepts terminal board-specific feedback, supporting either electromagnetic relays when paired with TRLYH1B, C, D, and F boards, or solid-state relays when used with TRLYH#E boards.

Applications

The IS220PDOAH1B is applied in power generation including heavy-duty gas turbines, steam turbines, and hydro generation controls, as well as oil and gas, petrochemical, and heavy industrial process industries. Operating as a discrete output unit within the Mark VIe system, the module functions to control and drive field equipment such as solenoid valves, motor starters, pumps, trip solenoids, indicator lights, and alarm devices to execute automated on-off control and safety interlocking.
