M730 Remote I/O Module

M730 Remote I/O Module

This M730 Remote I/O Module is a 3-channel temperature/mV/Ohm input module with RS485 communication . It provides isolation between each channel of inputs, power, and network circuits. Network communication adheres to the industry-standard RS-485Modbus RTU protocol. AC and DC power sources are supported with nonpolarized, diode-coupled terminals. Not only  works as an independent temperature transmitter isolator with communication，but combine with MWG1 to constitute a remote I/O DAS support both of MODBUS RTU and MODBUS TCP protocols.
