Description
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 unit. It is possible to connect 120 V/230 V AC actuators directly. The EtherCAT Terminal contains two channels that indicate their signal state by means of light emitting diodes. The EL1722 does not have any 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.
