Introduction

Two-channel digital input terminals 120...230 V AC, 10 ms, without power contacts

The EL1722 digital input terminal acquires the binary control signals from the process level and transmits them, in an electrically isolated form, to the higher-level automation device. The direct connection of 120 V/230 V AC signals is possible. The EtherCAT Terminal has two channels that indicate their signal state via light emitting diodes. The EL1722 has no power contacts. This makes it possible to create individual potential groups. The voltage between input 1 and input 2 must not exceed 230 V AC.
