Working Principle The UR9EH module operates as a distributed I/O processor within the GE Multilin control architecture. It continuously scans digital input channels, processes the input states, and communicates the data to the main controller via Ethernet or serial communication links. The module’s internal processor executes the configured logic, applying input filtering and debounce as programmed. Output commands from the main controller are received and executed with deterministic timing. The module’s real-time operating system ensures consistent scan times and reliable control performance.
