EtherCAT plug-in modules of the EJ series

EtherCAT plug-in modules of the EJ series

The EJ1254 EtherCAT plug-in module acquires the fast binary 24 V control signals from the process level and transmits them, in an electrically isolated form, to the controller. The module has four channels that indicate their signal state via light emitting diodes. The signals are furnished with a time stamp that identifies the time of the last edge change with a resolution of 1 ns. With this XFC technology, signal characteristics can be traced exactly in time and correlated with the distributed clocks system-wide. With this technology, machine-wide parallel hardware wiring of digital inputs or encoder signals for synchronization purposes is often no longer required.

 

Special features:

  • suitable for particularly fast signals due to very low input delay
  • synchronized operation through distributed clocks XFC technology possible
  • support of XFC technology timestamp

Product status:

regular delivery
