EL108x, EL109x - Introduction

Four- and eight-channel digital input terminals 24 V
The EL108x and EL109x digital input terminals acquire the binary control signals from the process level and
transmit them, in an electrically isolated form, to the higher-level automation device. The EL108x and
EL109x versions have input filters of different speeds. Four 2-wire sensors can be connected to the EL1084
and EL1094 EtherCAT Terminals. The EL1088 and EL1098 8-channel terminals are suitable for multi-
channel sensors with single-wire connections. The EtherCAT Terminals indicate their signal state by means
of light emitting diodes.
