Do the DP2302, DP2122 and DP2402 require a master to operate?

The DP2302 , DP2122 and DP2402 are IO-Link enabled devices. Using IO-Link, end users can configure the parameters of these units and collect additional process values and diagnostic data, however, these units’ parameters settings can also be configured directly on the display and used as a stand-alone device without an IO-Link master.

How are the DPs mounted?

If you do not wish to thread the DP directly to your master or sensor, the mounting clip E89208 can be used.

Product limits: How many DPs can fit on one master?

Depending on the orientation of the plug on the IO-Link master, it is possible that the converters cannot be screwed in directly next to each other. Then a master port has to be left free between them. Two DPs can be mounted next to each other when oriented with one or more flat sides next to each other: Mounting two DPs next to each other with their widest sides oriented the same way is not possible: Fully threading the DP into the port is not possible in this case.

Edge-controlled vs. pulse-controlled

Especially in processes with short switching pulses, it is a challenge for a control system and its input modules to reliably detect every single switching pulse of a sensor. This is where the pulse stretcher comes in: Using the input configuration “edge-controlled”, every input pulse, no matter how short, is output as a switching signal with a defined duration.

If you need the functionality of a timer relay, you can use the input configuration “pulse-controlled”. The switching delay allows you to suppress short input pulses or delay the switching of the outputs. The switch-off delay keeps the outputs active for the defined duration.
M12 connection technology allows field mounting of the pulse stretcher between the sensor and the input module. The parameters are set on the device or via IO-Link.
