I-7018R is an analog input module with an extremely excellent protection mechanism where over voltage protection is up to 240 Vrms. Its input type includes current, voltage as well as thermocouple. Naturally, I-7018R is an upgraded version of I-7018; the only difference is that the I-7018R is much more suitable for critically harsh environment! Moreover, a newly-added feature for open thermocouple detection makes I-7018R more sweet than ever. I-7018R also has qualifi cation for 4KV ESD protection and 3000 VDC intramodule isolation.
