DAT3020 Series
-
The DAT3020 series from Datexel is a range of Modbus analog output cards. These cards or modules have both voltage and current outputs either 0-10V or 4-20mA and are isolated from the input, output and power supply. They are available with either 2, 4 or 8 channels. The DAT3011 is a Modbus slave with 2 analog inputs (Thermocouple, RTD's mA, Resistance, Potentiometers, mV and voltage) and 2 analog outputs(4-20mA). It also has 3 digital inputs and outputs. Combining these analog output cards with the analog input cards, and the digital IO cards with the DAT9000 controllers make Datexel the smart choice where Data Acquisition is needed.
