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.
