Introduction
HD EtherCAT Terminals, 4 digital input channels, 24 VDC, three-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 contain four channels, consisting of signal input, 24 VDC and 0 V, whose signal state is indicated by LEDs. The power contacts are connected through.
In the EtherCAT Terminals EL1804 and EL1814, the reference ground for all inputs is the 0 V power contact. The variants have input filters with different speeds (EL1804: 3 ms; EL1814: 10 µs). The conductors can be connected without tools in the case of single-wire conductors using a direct plug-in technique.
The HD EtherCAT Terminals (High Density) with increased packing density are equipped with 16 connection points in the housing of a 12-mm terminal block.
