EL1808 | EtherCAT Terminal, 8-channel digital input, 24 V DC, 3 ms, 2-wire connection
The EL1808 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 contains eight channels, consisting of signal input and 24 V DC, whose signal state is indicated by LEDs. The power contacts are connected through. With the EL1808, the reference ground for all inputs is the 0 V power contact.
Special features:
- input specification type 1/3
- no bouncing due to mechanical switches thanks to 3 ms input filter
- tool-free connection by direct plug-in technique for solid wire conductors
- increased packing density with 16 connection points in the housing of a 12 mm terminal block
