Temperature/mV/Ohm to Current Signal Conditioner with RS485
This signal conditioner provides a single channel for temperature, mV, or Ohm input and a single channel current output. It uses RS485 communication and provides isolation between input channels, power, and network circuits.
Technical Specifications
Overview
M711 Remote I/O Module
The M711 is a versatile 1-channel signal conditioner designed for temperature, mV, and Ohm inputs with a 1-channel current output. It features robust 4-way isolation to eliminate ground loops and supports standard RS-485 Modbus RTU communication for seamless integration into industrial networks. With programmable input types, hot-swappable capability, and support for both AC and DC power, it is an ideal solution for remote I/O data acquisition systems.
