EL1104 | EtherCAT Terminal, 4-channel digital input, 24 V DC, 3 ms, 2-/3-wire connection
The EL1104 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
- +24 V and 0 V sensor supply connections
