The GE IS220PDOAH1A is a Proportional Digital Output Module, a key component in GE's Mark VIe Series for distributed gas turbine control systems. It serves as an electrical interface between 1-2 I/O Ethernet networks and discrete output terminal boards, integrating a common Mark VIe processor board and a discrete output-specific acquisition board.

• Relay Control: Manages up to 12 relays, compatible with electromagnetic and solid-state types
• Flexible Configurations: Supports simplex, dual, and TMR setups, adapting to diverse system redundancy needs
• Easy Installation: Plugs directly into terminal boards with threaded studs for secure connection
• Robust Communication: Dual 10/100 Ethernet ports with DHCP for network addressing
• Processor & Safety Features: High-speed processor with flash/RAM, hardware watchdog, and ambient temperature sensor
• Diagnostics: LED status indicators and infrared serial port for real-time monitoring

Communication occurs via dual RJ45 Ethernet ports, with power supplied through a three-pin connector, and outputs routed via a DC-37 pin connector to terminal boards. The module includes LED indicators and an infrared port for visual and serial diagnostics.
