ETH-MODBUS-IO8R-A

ETH-MODBUS-IO8R-A module is a multi-function serial port server. In addition to the on-off data acquisition and control, analog data acquisition, and output channels, the RJ45 interface is added to make it work on Modbus RTU function for serial communication, by increasing the conversion of Modbus TCP protocol communication with the network interface equipment, the equipment with RS485 interface can be connected to TCP/IP network through the two-way transparent transmission between RS485 serial port and Ethernet. At the same time, 2 independent RS485 serial ports extend 1 physical communication link. More support dial code set serial port baud rate, station number, “6 in 1” RTU from Modbus station, and other practical functions, is economic stability, powerful products.

The ETH-MODBUS-IO8R-A is an industrial networking module that allows you to connect digital inputs, digital outputs, analog inputs, and analog outputs to an Ethernet network. It supports the Modbus TCP, Modbus RTU, and TCP protocols, and it can be used as a network server or client. The module has a built-in function that allows it to convert Modbus RTU slave stations into a Modbus TCP server, and it can also be used to convert Modbus TCP to Modbus RTU. The module has an RJ45 port for Ethernet communication and a DB9 connector for connecting to a master device. It is suitable for use in a variety of industrial applications where signal acquisition and control of field equipment are required.
