EL1024, EL1034 - Introduction

EL1024 - four-channel digital input terminals 24 V
EL1034 - four-channel digital input terminals 24 V
The EL1024 digital input terminal acquires the binary 24 V control signals and transmits them, in an
electrically isolated form, to the higher-level automation system. The EtherCAT Terminal contains four
channels that indicate its signal state by means of light emitting diodes. With its input signal the EL1024
corresponds to IEC 61131-2, Type 2. Additionally, the 4-channel EtherCAT Terminals enable the direct
connection of four 2-wire sensors. Four +24 V connection points are provided.
The EL1034 features electrical isolation of the individual channels. With its input signal it corresponds to IEC
61131-2, Type 1.
