ET-7002 Ethernet I/O Module 3 AnaI, 6 DigI/Count + 3 RelayO

Description

The ET-7002 is a multi-function Ethernet based data acquisition module that 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.

Configuration of the module is done via its integrated Web Server, while communication to a Data Logging / SCADA Package can be achieved using the ModbusTCP protocol.
