EtherCAT plug-in modules of the EJ series
Efficient series machine manufacturing: plug-and-play in the control cabinet
EtherCAT plug-in modules: Bus Terminals for circuit boards
The EJ1889 digital input acquires binary 24 V control signals from the process level and transmits them, in an electrically isolated form, to the higher-level automation unit. The EtherCAT plug-in module contains 16 channels, whose signal state is indicated by LEDs.
Special features:
- ground switching
- no bouncing due to mechanical switches thanks to 3 ms input filter
