ET-7228

Introduction: The ET-7228 is an Ethernet I/O module with 8 analog output channels and a built-in 2-port Ethernet switch for daisy-chain topology. It supports Modbus TCP and UDP protocols and includes a web server and Web HMI for remote monitoring and control. Each analog output channel is jumper-selectable for voltage or current output, making it ideal for industrial automation, remote diagnostics, and building management systems.
