                                        What It Does (Simple Explanation)

                                        The relay continuously monitors pulses from proximity sensors installed on a rotating shaft or moving mechanism.

                                        Working process:

                                        1. Proximity sensors detect shaft rotation.
                                        2. The relay calculates the pulse frequency.
                                        3. When the speed drops below the preset threshold—or reaches standstill—the relay energizes its safety outputs.
                                        4. The machine can then safely unlock guards or permit maintenance.

                                        This helps prevent personnel from accessing machinery while hazardous motion is still present.
