M240-Remote I/O Module

This signal conditioner is a 4-channel discrete input module with RS485 . 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 signal isolator with communication，but combine with MWG1 to constitute a remote I/O DAS support both of MODBUS RTU and MODBUS TCP protocols.

Features

• Substitute the analog isolator into the communication isolator

• Six-way isolation eliminates potential ground loops between power, Input,output, and network circuitry

• Hot Swappable

• 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
