M-7011D-G

  • 1 Analog Input
  • Current, Voltage, and Thermocouple Inputs
  • Open Thermocouple Detection
  • High Resolution: 16-bit
  • 50 Hz Event Counter for Digital Input
  • High/Low Alarm for Digital Output
  • Built-in Dual Watchdog

Introduction

The M-7011/M-7011D features current and voltage input as well as thermocouple input. The module provides 1-channel analog input, 1-channel digital input that functions as a 50 Hz event counter, and 2-channel digital output that can be used as a high/low alarm. The module also features open wire detection for the thermocouple input, and 3000 VDC intra-module isolation. The M-7011(D) supports Modbus RTU and DCON protocols, which can be configured via software, and all hardware specifications are the same as the I-7011(D).
