Beckhoff EJ3108 EtherCAT plug-in module

Beckhoff EJ3108 EtherCAT plug-in module

The EJ3108 EtherCAT plug-in module processes signals in the range between -10 and +10 V. The voltage is digitized to a resolution of 16 bits, and is transmitted, electrically isolated, to the higher-level automation device. Of the eight input channels, six are designed as differential and two as single-ended inputs. The signal state is indicated by light emitting diodes.
