The device DAT 7015 is able to acquire up to 4 voltage signals up to ± 10 V or current signals up to ± 20 mA. The data are transmitted by the CANopen protocol. By means of 16 bit converters, the device guarantees high accuracy and a stable measures both versus time and temperature. The 2000 Vac galvanic isolation between inputs, power supply and data line eliminates the effects of all ground loops eventually existing and allows the use of the device in heavy environmental conditions found in industrial applications.
