Module RS-485 Modbus RTU 8 kênh đầu vào tương tự (Dòng điện, điện áp, cặp nhiệt) ICP DAS M-7018R-G CR

Features

  • 8 Differential Analog Inputs
  • Current, Voltage, and Thermocouple Inputs
  • High Over-voltage Input Protection
  • Built-in Dual Watchdog

Introduction

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



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

Applications

• Building Automation
• Factory Automation
• Machine Automation
