The EL1012 digital input terminal acquires the binary 24 V control signals from the process level and transmits them, in an electrically isolated form, to the higher-level automation unit. The EtherCAT Terminal has two channels that indicate their signal state via light emitting diodes.

Special features:

• input specification type 1/3
• low delay due to fast 10 µs input filter
• usable, for example, for inductive or capacitive sensors
