Rotation direction safety monitor SAFEONE DN3PR1

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. •No Sensor necessary •No parameterisation necessary •Fits every switch cabinet 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.
