The EJ1128 EtherCAT plug-in module acquires the binary 3.3 V / 5 V control signals from the process level and transmits them, in an electrically isolated form, to the higher-level automation unit. The module contains eight channels which indicate their signal state by means of light emitting diodes. The inputs are implemented with HCT-CMOS technology, i.e. the resulting switching thresholds allow sensors with both HC-CMOS and TTL outputs to be connected to the input. The supply voltage can be generated with the EJ9505.

 

Special features:

  • low delay due to fast 0.05 µs input filter
  • direct connection of sensors with HC-CMOS or TTL output

Product status:

regular delivery
