M-7018-G

  • 8 Differential, or 6 Differential and 2 Single-ended Analog Inputs
  • Current, Voltage, and Thermocouple Inputs
  • Built-in Dual Watchdog

Introduction

The M-7018/M-7018R is an 8-channel analog input module that supports current, voltage, and thermocouple input. The M-7018R is an upgraded version of the M-7018 that includes an extremely high-quality protection mechanism where the overvoltage protection can be as high as 240 Vrms. The M-7018R is more suitable for critically harsh environments, and the newly-added open thermocouple detection feature makes The M-7018R more attractive than ever.

The M-7018/M-7018R also features 4 kV ESD protection and 3000 VDC intra-module isolation. The M-7018/M-7018R supports Modbus RTU and DCON protocols, which can be configured via software, and all hardware specifications are the same as the I-7018/I-7018R.
