Acquire external field dry‑contact status signals, convert contact status into internal digital logic signals for protection IED. Signal status can be displayed on local HMI and uploaded to station control system. Channel filtering parameters can be configured via engineering tool to avoid signal bounce mis‑operation. Built‑in board self‑diagnosis function for hardware fault detection and status reporting to main unit.

Plug directly into the corresponding rear slot of Relion series protection device, ensure complete insertion and tighten fixing screws. Match external input voltage with module rated voltage range. After replacement, download parameter configuration, perform channel point‑to‑point signal test, verify each binary input channel status feedback.

Installed inside REF, RED, REG series protection relays, widely used in power plants, high‑voltage substations and industrial power distribution secondary systems. Collect breaker, disconnector and interlock switch auxiliary status signals.
