EL1712-0020 | 2-channel digital input terminal 120 V DC

The EL1712-0020 digital input terminal acquires binary control signals from the process level and transmits them, electrically isolated, to the higher-level automation device. Direct connection of DC actuators is possible. The EtherCAT Terminal offers two channels that indicate their signal state via light emitting diodes.
