M-7051D-G

  • 16 Digital Inputs
  • Dry Contact and Wet Contact Selectable via Wire Connections
  • Photocoupler Isolation
  • Long Distance Measurement
  • All Channels Can be Used as 16-bit Counters
  • Built-in Dual Watchdog

Introduction

The M-7051/M-7051D offers 16 channels for digital input, catering for both dry and wet contact, with an effective distance of up to 500 meters for dry contact. All channels not only feature photocoupler isolation but also be used as 16-bit counters. The M-7051D has 16 LED indicators for channel status monitoring. The M-7051(D) supports Modbus RTU and DCON protocols, which can be configured via software. 4 kV ESD protection and 3750 VDC intra-module isolation are standard, and all hardware specifications are the same as the I-7051(D).
