ET-7002 Modbus TCP Based Remote Ethernet I/O Data Acquisition module

With 3-channel Voltage & Current inputs, 6-channel Digital Inputs and 3-channel Relay Outputs. Analog inputs are: +/- 150 mV,+/- 500 mV, +/- 1V, +/- 5 V, +/-10 V + 0 mA ~ + 20 mA, +/- 20 mA, 4 ~ 20 mA (jumper selectable). Communicable over Modbus TCP and UDP. Supports operating temperatures between -25 to 75°C (-13F ~ 167F) and has a din rail mount.

The ET-7002 is a web-based Ethernet I/O module that features a built-in web server which allows remote configuration, 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 easy for engineers in the future. The ET-7002 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.

The ET-7002 is a multi-function module provides 3 analog input channels, 6 digital input channels and 3 relay output channels. A programmable input range is provided on all analog inputs (+/- 150 mV, +/-500 mV, +/-1 V, +/-5 V, +/-10 V, +/-20 mA, 0~20 mA and 4~20 mA). The range for each analog input can be configured individually and each input has a high overvoltage protection of 240Vrms. The analog inputs are also jumper selectable for either voltage or current inputs. The ET-7002 is fully RoHS-compliant and provides 4 kV ESD protection, 3 kV surge protection as well as 2500 VDC intra-module isolation.
