EL1004 Beckhoff
4-channel digital input terminal 24 V DC, 3 ms
The EL1004 digital input terminal acquires the binary control signals from the process level and transmits them, in an electrically isolated form, to the higher-level automation unit. Digital input terminals from the EL100x series have a 3 ms input filter. The EtherCAT Terminals indicate their state via an LED.
