EL1702-0020 | 2-channel digital input terminal 220 V DC

The EL1702-0020 digital input terminal acquires the binary control signals from the process level and transmits them, electrically isolated, to the higher-level automation device. Direct connection of DC sensors is possible. The EtherCAT Terminal has two channels that indicate their signal state via light emitting diodes.
