The IS220PDOAH1A REV E is a Discrete Output Module from General Electric, tailored for integration within the GE Mark VIe distributed control system. This robust I/O pack delivers twelve optically isolated 24 VDC output channels, providing precise digital control for actuating field devices such as solenoids, relays, contactors, and valves.

With support for both simplex and triple modular redundant (TMR) configurations, the IS220PDOAH1A ensures high availability and fault tolerance, making it ideal for use in gas turbines, steam turbines, and balance of plant applications. Each output is independently protected and monitored, offering real-time status indicators (LEDs) and internal diagnostics to ensure safe and consistent operations.

The module’s optical isolation shields sensitive electronics from electrical disturbances, enhancing system durability and reliability in demanding industrial environments. Hot-swap capability allows engineers to replace or upgrade the module without shutting down the entire system, minimizing downtime.

The IS220PDOAH1A REV E connects seamlessly to matching terminal boards using plug-and-play ribbon cables, reducing wiring complexity and installation time. Its compact form factor and rugged design make it a dependable solution for industrial environments where vibration, temperature fluctuations, and EMI are prevalent.

Whether used in standalone or redundant setups, this module contributes to safe, real-time command execution within your GE Mark VIe control network.
