Introduction

The I-7018P is an Analog Input module that features current and voltage input, as well as thermocouple input. The I-7018BL is a thermocouple input module. Both of the modules provide 8-channel differential or 6-channel differential and 2-channel single ended input that can be selected via a jumper, and all channels can be configured for the same input type. Note that an optional external 125 Ω resistor is required for current input. The modules also feature 3000 VDC intra-module isolation as well as ±35 VDC overvoltage protection. The I-7018BL provides thermocouple open wire detection and the I-7018P provides support for two additional thermocouple types, L and M.
