EL1804 | HD EtherCAT Terminal, 4-channel digital input 24 V DC, 3-wire connection
The digital input terminal EL1804 acquires the binary control signals from the process level and transmits them, in an electrically isolated form, to the automation unit at a higher level.
EtherCAT Terminal contains four channels consisting of a signal input, 24 V DC and 0 V.
The signal states are indicated by LEDs.
The power switches run through.
For EL1804, the reference ground for all inputs is the 0 V power switch.
The wires can be connected without tools in the case of solid wires using a direct plug-in technique.
HD EtherCAT Terminals (High Density) with increased packing density have 16 connection points in the housing on a 12 mm clamp.
EtherCAT terminal housing
The EtherCAT terminals have different housings.
They are available with up to three power switches and can have a range of voltages.
It must be ensured that a voltage change always starts with a power supply terminal.
