ET-7026
6-channel Analog Input, 2-channel Analog Output, 2-channel Digital Input
and 2-channel Digital Output Module
ET-7026
Introduction
The ET-7026, a web-based Ethernet I/O module, features a built-in web server, which allows configuration, I/O monitoring and
I/O control by simply using a regular web browser. Besides, with the web HMI function, no more programming or HTML skills
are needed; creating dynamic and attractive web pages for I/O monitoring and I/O control would be fun to engineers ever after.
The ET-7026 offers easily and safely access for users from anytime and anywhere! In addition, ET-7026 also supports
Modbus/TCP protocol that makes perfect integration to SCADA software.
The ET-7026 is a multi-function module, there are 6-channel analog inputs, 2-channel analog output, 2-channel digital inputs
and 2-channel digital outputs module. It provides programmable input range 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 and digital output
can be set alarm output. Each analog input is allowed to configure an individual range and has 240Vrms high over voltage
protection. Jumper selectable for voltage or current inputs/outputs.
