The Beckhoff ER3204-0002 EtherCAT Box delivers reliable 4-channel RTD temperature acquisition directly in the field. Engineered for decentralized I/O on machines and process equipment, its zinc die-cast housing and IP65/66/67 protection enable precise, long-term performance in demanding industrial environments.

Compatible with Pt100, Pt200, Pt500, Pt1000, Ni100, Ni120 and Ni1000 as well as resistance measurement, the module covers -200 to +850°C for Pt sensors and -60 to +250°C for Ni sensors. It offers 0.1°C per digit resolution with a default conversion time of approximately 85 ms, 500 V electrical isolation and open-circuit recognition for dependable diagnostics. Installation is fast via M12 sockets for 2-, 3- and 4-wire connections, while two a-coded, shielded M8 interfaces provide EtherCAT communication and power feed-through at 24 V DC (−15%/+20%).

Whether modernizing existing lines or designing new machinery, the ER3204-0002 streamlines cabinet-free temperature measurement, reduces wiring complexity and maintains high data quality in harsh conditions—making it a practical choice for OEMs and integrators, and backed by a 1-year warranty for added peace of mind in continuous operation.
