EL1702 | 2-channel digital input terminal 120…230 V AC

The EL1702 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 sensors directly. The EtherCAT Terminal contains two channels that indicate their signal state by means of light emitting diodes.
