EL1012, EL1014, EL1018 - Introduction
Two-, four- and eight-channel digital input terminals 24 V
DC
, 10 µs input filter
The EL101x digital input terminals acquire binary control signals from the process level and transmit them, in
an electrically isolated form, to the higher-level automation device. They differ in the number of channels and
the pin assignment. The digital input terminals of the EL101x series feature an input filter (10 µs) and
indicate their signal state through an LED for each channel.
