"Data transmission" is the transfer of characters, numbers, statuses, measurements, etc. between different, decentralised units. "Decentralised units" are controls, computers, measurement sensors, actuators, etc. Appropriate overvoltage protection is essential for such sensitive areas. Weidmüller can offer a wide range of solutions.
Protective module for mounting rail or as socket-adapter enclosure
Serial interface for point-to-point connections up to 20 kBit/s earth-related voltage signal: logical one (mark) -15 V to -3 V logical zero (space) +3 V to +15 V max. signal level +/-15 V Cable length up to 20 m, depending on the transmission rate.
