Introduction
The I-87018W is an 8-channel analog input module that provides current input and voltage input, as well as thermocouple input. The I-87018RW is an upgraded version of I-87018W with an extremely highquality protection mechanism where the overvoltage protection can be as high as 240 Vrms. The input type can be set to either current or voltage, as well as thermocouple. The only difference between the two modules is that the I-87018RW is more suitable for critically harsh environments. Moreover, the newly-added open thermocouple detection feature makes the I-87018RW more attractive than ever. Both the I-87018W and the I-87018RW also features 4 kV ESD protection and 3000 VDC intra-module isolation.
