Beckhoff EJ3104 EtherCAT plug-in module

Beckhoff EJ3104 EtherCAT plug-in module

The EJ3104 EtherCAT plug-in module processes signals in the range from -10 to +10 V. The voltage is digitized to a resolution of 16 bit, and is transmitted, electrically isolated, to the higher-level automation device. The input channels are designed as differential inputs.
