"The 1794-IR8 is an analog input module that is especially designed to interface Resistance Temperature Detectors (RTD) sensors. This module has Eight (8) RTD channels compatible for a wide variety of RTD sensors. It supports 2-wire or 3-wire sensors. This module eliminates the need of transmitter for interfacing temperature applications as it allows an RTD sensor to be directly wired to any of the module’s channels. " -DO Supply Tech
