Inquire NowM711-Remote I/O Module
The M711-Remote I/O Module is a versatile signal conditioner designed to enhance measurement capabilities in various applications. This module features a 1-channel temperature/mV/Ohm input and a 1-channel current output with RS485 communication, ensuring efficient data transfer and integration. It offers complete isolation between each channel of inputs, power, and network circuits, providing reliability in performance.
Built to support both AC and DC power sources, the M711 module utilizes nonpolarized, diode-coupled terminals for ease of connection. It operates seamlessly as an independent temperature transmitter isolator with communication capabilities or can be combined with the MWG1 to form a remote I/O Data Acquisition System (DAS) that supports both MODBUS RTU and MODBUS TCP protocols.
Features
- 1-channel Temperature/mV/Ohm Input, 1-channel Current Output
- 4-way isolation prevents potential ground loops between power, input, and network circuitry
