The EL1098 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 unit. Each EtherCAT Terminal has eight channels that indicate their signal state via light emitting diodes.

Special features:

• ground switching
• low delay due to fast 10 µs input filter
• usable, for example, for inductive or capacitive sensors
• direct connection of multi-channel sensors using 1-wire connection technique
