Rotational Direction Monitor SAFEONE DN3PR1
The rotational direction monitor DN3PR1 does not require a measuring system nor external sensors and are therefore unique on the market in this way.
Thus, the innovative DN3PR1 is a good choice for retrofits as well as the most modern machines up to Performance Level e.
The simple installation and user-friendly parameterisation make safety a breeze. Just quickly configure the most essential parameters, since we have already done everything else for you.
Safe direction monitoring easier than ever.
For safe monitoring of three-phase asynchronous motors up to 690V AC with Performance Level e, it is not even necessary to parameterise the device. The module measures the frequency of the 3 motor phases as long as the drive is running. The output provides a signal when the drive moves in the preset, desired direction. However, the contact output opens immediately if the drive moves in a different, wrong direction, which breaks the circuit and stops the drive.

Block circuit diagram
|Measurement Inputs||The Measurement inputs U, V, W of the DN3PR1 are directly connected to the three phases of the motor M.|
|Safe Switch Off||When the DN3PR1 detects a change of direction, the enabling current paths
current paths 13/14, 23/24 open and switch off the motor in a safety-oriented manner,
|Resetting the safety function||The S1 acknowledgement button is used to reset the safety function after the motor has turned in the preferred direction again the motor rotates in the preferred direction again.|
|Monitoring of external
|The external, positively-driven contactors K1, K2 are integrated into the start circuit of the
of the safety switchgear.

Your advantages summarised.
No external measurement systems equals less components, lower costs as well as faster Certification and Validation.
Can be used on all three-phase and single-phase motors up to Performance Level e, regardless of supplier and system.
Fits into every cabinet
With an overall width of only 22,5 mm/0.9 in
Model-dependent via USB interface on the PC or directly via SET key. In the case of the direction of rotation monitor, no parameterisation is necessary at all.
Plug & Play
Easy to put into action without a great deal of prior knowledge. Integration into the circuit diagram is also very simple.
