M-7033D-G 3ch RTD Input Module with LED Display


  • 3 RTD Inputs
  • Lead Resistance Elimination for 3/4-wire Connections
  • Open Wire Detection
  • Built-in Dual Watchdog


The 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. The M-7033(D) also includes 3000 VDC intra-module isolation and supports lead resistance elimination for 3/4-wire connections. The M-7033(D) supports Modbus RTU and DCON protocols, which can be configured via software.

Channel Safe Isolation: 

The “R” and “Z” version of analog input modules provide +/-400 VDC virtual channel to channel isolation to avoid the noise interference from adjacent channel in the industrial environment. To name a few of the modules, they are I-7017R, I-7017Z, I-7018R, I-7018Z, I-7019R, and I-7019Z. Though it is not real channel to channel isolation, there is only 1uA leakage current between two adjacent channels and the interference is very small and can be negligible.
