M730-Remote I/O Module

This signal conditioner 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.

Features

• 3-channel Temperature/mV/Ohm Input

• Five-way isolation eliminates potential ground loops between power, Inputand network circuitry

• The input type & measurement range can be programmed setting by ZPconfig software through a separate USB adaptor

• Hot Swappable

• Low Power Loss, Low Temperature Drift, Auto Zero Calibration

• Terminal Block & Rail bus redundant power

• Standard Modbus RTU protocol with high-speed RS-485 communication (up to 115K bps)

• Combine with MWG1 to constitute a remote I/O DAS support both of MODBUS RTU and MODBUS TCP protocols
