Description

The EP1518 EtherCAT Box modules with digital inputs acquire binary control signals from the process level and transmit them, in an electrically isolated form, to the controller. The signal state is displayed by light emitting diodes. The signals are optionally connected via M8 (EP1518-0001) or M12 (EP1518-0002) screw type connectors.

Features

• Inputs 0 and 4 can be used as 32-bit up/down counters.
• Sensors are supplied via the control voltage U_S in two groups of four sensors each.
• Any short circuits on the sensor side are detected and reported to the controller.
• The load voltage U_P is not used in the input module, but may optionally be connected in order to be relayed downstream.
