Two-, four- and eight-channel digital input terminals 24V
DC
, 3ms input filter
The EL1002, EL1004 and EL1008 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 EL100x series feature an input
filter (3ms) and indicate their signal state through an LED for each channel.
The variant of the EL1004-0020 is designed with a functional potential separation of 2500 V (test voltage E-
bus / field voltage).
