Features

Application Image ET-7026

ET-7026 is a web-based Ethernet I/O module that features a built-in web server which allows configuration, I/O monitoring and I/O control through a regular web browser. With the web HMI function, no programming or HTML skills are needed; creating dynamic and attractive web pages for I/O monitoring and I/O control is easy. ET-7026 offers easy and safe access for users from anytime and anywhere! ET-7026 also supports Modbus/TCP protocol that makes perfect integration to SCADA software.

ET-7026 is a multi-function module. It has 6 analog input channels, 2 analog output channels, 2 digital input channels and 2 digital outputs channels. It provides programmable input ranges on all analog inputs (±500mV, ±1V, ±5V, ±10V, ±20mA, 0~20mA and 4~20mA). Analaog outputs are 12 bit with ±5V, ±10V, 0~20mA and 4~20mA. Digital outputs can be set up with alarm output. Each analog input is configurable by an individual range and has 240Vrms high over voltage protection. Jumper selectable for voltage or current inputs/outputs.
