EP1816-0008 | 16-channel digital input 24 V DC

The EP1816 EtherCAT Box with digital inputs acquires the binary control signals from the process level and transmits them, in an electrically isolated form, to the controller. The state of the signals is indicated by light emitting diodes. The signals are connected via 25-pin D-sub socket.

The sensors are supplied from the box supply voltage US. The auxiliary voltage UP is not used in the input module, but may be connected in order to be relayed downstream.
