Product overview
5.1
Function
The module provides digital inputs for the connection of sensors in an automation system CPX-AP,
thereby enabling the recording and further processing of digital input signals. The sensors are sup-
plied by the module with a voltage of 24V DC and return a logic 0 or 1 to the inputs.
The module behaviour can be parameterised
è
Status and error messages can be shown by LED indicators on the module and reported to the inter-
face via the system communication.
The sensor supply has an electronic fuse for protection against short circuit or overload. If this elec-
tronic fuse responds, the sensor supply of the module is switched off and the error is shown by an LED
indicator on the module. After the elimination of the short circuit or the overload, the sensor supply is
switched on again automatically. The electronic fuse of the module is slow-blowing. Sensors can
therefore also be connected with a temporarily higher current requirement.
