EL1002, EL1004-00x0, EL1008 - Introduction
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).
