What requirements should connectors for remote I/O modules of DCS systems meet?

Q: What requirements should connectors for remote I/O modules of DCS systems meet?

A: They need to be compatible with Profinet/Modbus bus protocols. The XS series (IP65) is recommended. With 10~40 pins, it can be adapted to the signal aggregation of multiple sensors (temperature, pressure, flow rate). It supports DIN rail mounting (saving space) and has a transmission distance of ≤1,000 meters (extendable to 10km via repeaters). Meanwhile, it features electromagnetic interference resistance (shielding effectiveness ≥70dB), making it suitable for the complex electromagnetic environment of workshops.
