Introduction
M-7033/M-7033D is a 3-channel RTD input module that is used for measuring temperatures via an RTD sensor and supports Pt100, Ni120, and Pt1000 types of sensors. The module allows 2/3/4-wire RTD connections and features open-wire detection. M-7033(D) also includes 3000 VDC intra-module isolation and supports lead resistance elimination for 3/4-wire connections. M-7033(D) supports Modbus RTU and DCON protocols, which can be configured via software.
