The CDE connection module enables easy and cost-effective integration of SICK sensors into Power over Ethernet (PoE) environments. The connection module can be used, for example, to integrate 4Dpro identification sensors such as 1D and 2D code readers and RFID read/write devices into such environments. The CDE acts as a PoE splitter, splitting PoE signals into a 24-volt voltage supply and an Ethernet data line. Depending on the device version, the LEDs integrated in the housing cover of the connection module visualize the received sensor signals. Digital input and output signals can be integrated using an additional I/O connection. With two screws and a plug-in type suitable for all electrical connections, the CDE is very easy to mount on the system.
