About this manual

The MCR-PLUGTRAB PT is a pluggable surge protection module that safeguards both the 24 VDC power supply and the CAN‑high/CAN‑low data signals in DeviceNet and other CAN‑based networks. It consists of a DIN‑rail‑mounted header and a replaceable plug, with color‑coded keys to prevent mismatched connections.

The document provides dimensions, a circuit diagram, technical data (voltage, current, surge ratings, response time, temperature range), detailed installation and removal instructions for the DIN‑rail header, and ordering data for the header, plug and accessories.
