The ET-7026/PET-7026 is a multi-function ethernet-based Data Acquisition module with 6 analog inputs, 2 analog output, 2 channel digital inputs / counters and 2-channel digital output channels. Each of the Analog Input channels has a programmable input range (+/-500 mV, +/-1 V, +/-5 V, +/-10 V, +/-20 mA, 0~20 mA and 4~20 mA), with a jumper selection to choose Voltage or Current Inputs modes. Each Analog Input also has 240 Vrms high overvoltage protection . The Analog outputs are 12 bit with +/-5 V, +/-10 V, 0~20 mA and 4~20 mA ranges.
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.
