EL1804, EL1814 | HD EtherCAT Terminals, 4-channel digital input 24 V DC, 3-wire connection

The EL1804 and EL1814 digital input terminals acquire the binary control signals from the process level and transmit them, in an electrically isolated form, to the higher-level automation device. The EtherCAT Terminals each contain four channels, consisting of a signal input, 24 V DC and 0 V. The signal states are displayed by LEDs. The power contacts are looped through.

For the EL1804 and EL1814 EtherCAT Terminals, the reference ground for all inputs is the 0 V power contact. The versions have input filters with different speeds. The wires can be connected without tools in the case of solid wires using a direct plug-in technique.

The HD EtherCAT Terminals (High Density) with increased packing density feature 16 connection points in the housing of a 12 mm terminal block.
