The ZB-2018-T an analog input module with an extremely excellent protection mechanism where overvoltage protection is up to 240 Vrms. Its input type includes current, voltage as well as thermocouple. It is much more suitable for critically harsh environment! Moreover, a newly-added feature for open thermocouple detection makes ZB-2018-T more sweet than ever. ZB-2018-T also has qualifi cation for 4 kV ESD protection and 3000 VDC intra-module isolation. Users can be easy to confi gure the module address, Protocol, Checksum, ZB-PID, ZB-ch and type code by rotary and DIP switch.
