ETH-MODBUS-I32 RTU Protocol RS485 PLC Extensible Module 32 Channel Input Switch Quantity Acquisition IO module Digital


ETH-MODBUS-I32 module is a multi-functional serial server, which not only has its own switch acquisition channel, but also includes RJ45 interface, so that it can add the conversion of MODBUS TCP protocol communication with network devices to the MODBUS RTU function used for serial communication, and also make the RS485 devices with RS485 interface have the ability to connect to TCP/IP networks through transparent bi-directional transmission between RS485 serial port and Ethernet. interface can be connected to a TCP/IP network. At the same time, two independent RS485 serial ports extend one physical communication link. It also supports dialing code to set serial port baud rate and station number, “6-in-1” MODBUS RTU slave, etc. It is an economical and stable product with powerful functions.

  • 32 optoisolated digital inputs (corresponding to the number of status indicators)
  • 2 x 485 interface, 1 x DB9 female, 1 x terminal, independent use
  • 1 RJ45 type network port, 10/100Mbps Ethernet communication
  • With baud rate, station number dial switch, easy to set module parameters
  • Support MODBUS TCP, MODBUS RTU and TCP protocols, support 4 MODBUS TCP connections at the same time
  • system built-in MODBUS TCP to MODBUS RTU, MODBUS RTU to MODBUS TCP; can be used as MODBUS TCP network server or client
  • supports conversion of up to 6 MODBUS RTU slaves with this module into 1 MODBUS TCP of corresponding configuration points Server control
  • dedicated upper computer can set the module parameters for permanent storage
  • Power supply circuit with anti-reverse connection design
