EL1819 | HD EtherCAT Terminal, 16-channel digital input
24 V DC
The EL1819 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 device. The EtherCAT Terminal contains 16 channels, whose signal states are displayed by LEDs. The terminal is particularly
suitable for space-saving use in control cabinets. By using the single-conductor connection technique, a multi-channel sensor can be connected in the
smallest space with a minimum amount of wiring. The power contacts are looped through.
For the EL1819, the reference ground for all inputs is the 0 V power contact. The conductors 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.
