Beckhoff EL1004 EtherCAT Terminal, 4-channel digital input, 24 V DC, 3 ms

10 in stock

The EL1004 digital input terminal acquires the 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 Terminal has four channels that indicate their signal state via light emitting diodes.

Special features:

  • input specification type 1/3
  • no bouncing due to mechanical switches thanks to 3 ms input filter
  • direct connection of four 2-wire sensors via additional +24 V connection points
