16 digital inputs 24 V
DC
The EP1809­0022 and EP1819­0022 modules with digital inputs acquire the binary control signals from the
process level and transmit 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 M12 connectors. These versions are
distinguished by input filters of different speeds.
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.
