The EL1899 digital input terminal acquires the binary 24 V DC

control signals from the process level and transmits them, in an

electrically isolated form, to the higher-level automation unit.

The EtherCAT Terminal has 16 channels, whose signal states

are indicated by LEDs. The power contacts are connected

through. With the EL1899. the reference ground for all inputs

is the 24 V DC power contact.

Special features:

• ground switching

• low delay due to fast 10 µs input filter

• tool-free connection by direct plug-in technique for solid wire

conductors

• space-saving use in the control cabinet

• direct connection of multi-channel sensors using 1-wire

connection technique in the smallest space
