The data are transmitted by the CANopen protocol. 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. The ECAN 7148 is housed in a rough self-extinguishing...
