Beckhoff EL1819

Beckhoff EL1819 EtherCAT Terminal

The Beckhoff 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 connect 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.
