The ET-7016/PET-7016 is a web-based Ethernet I/O module that features a built-in web server which allows remote confi guration, I/O monitoring and I/O control simply by using a regular web browser. Remote control is as easy as surfing the Internet. In addition, the web HMI function means that programming or HTML skills are no longer required so creating dynamic and attractive web pages for I/O monitoring and I/O control purposes will be more fun for engineers in the future. The ET-7016/PET-7016 offers easy and safe access for users at anytime and from anywhere, and also supports the Modbus/TCP protocol that ensures perfect integration with SCADA software.

Furthermore, the PET-7016 features “PoE”, meaning that not only is data transmitted through an Ethernet cable but also power making installation of the PET-7016 a piece of cake. Imagine no more unnecessary wires with only an Ethernet cable being required to take care of everything in the field.

The ET-7016/PET-7016 is a strain gauge module providing are 2 analog input channels, 1 excitation voltage output channel, 2 digital input channels and 2 digital output channels module. It provides a programmable input range on all analog inputs (+/-1mV, +/-50mV, +/-100mV, +/-500mV, +/-1V, and +/-2.5V) and supports full-bridge, half-bridge, and quarter-bridge. The range for each analog input is allowed to be configured individually. Excitation voltage output can be in the range of 0 ~ 10V with a 60mA driving efficiency. Digital outputs can also be set as alarm outputs. The ET-7016/PET-1016 can also provide long-distance strain gauge measurement that compensates for the loss of voltage resulting from long-distance measurements.
