Overview
The GE IS220PDOAH1B module acts as a critical interface between the turbine controller and discrete field actuators, converting digital control signals into high-speed, high-integrity binary outputs. It is widely deployed in power generation, oil & gas, and marine propulsion systems, where deterministic control and system uptime are essential.
Moreover, the module supports hot-swapping, allowing maintenance or replacement without system shutdown. It also features dual redundant power inputs and real-time health diagnostics, enhancing system availability and simplifying troubleshooting. The IS220PDOAH1B connects to the IS230SNRLH2A terminal board, ensuring secure and reliable field wiring.
Its compact DIN rail–mountable design makes it suitable for modern control cabinets, particularly in retrofit or space-constrained applications.
