Preventa Cat. 3 Safety Relay XPSVNE----P 24V dc

For zero speed detection. 24V dc. The XPSVNE most common applications include providing the unlock signal for electrically interlocked sliding or removable machine guards, controlling rotation direction signals for reversing motors and engaging locking brakes after a motor has come to a standstill. The cabling between the motor windings and the inputs of the XPSVNE module is also monitored to prevent a cabling breakage or anomaly being seen as a stopped motor. The input filters for standard XPSVNE modules are designed for a frequency of up to 60 Hz.
For motors operating at a frequency higher than 60 Hz, which therefore produce a high frequency remanent voltage, special modules XPSVNE----HS should be used. The XPSVN is not compatible with Wound Rotor Motors and is not designed to detect locked rotor conditions.
The XPSVNE modules incorporate 2 solid-state outputs for PLC signalling and 4 LEDs to provide information on the monitoring circuit status. These modules also have two potentiometers mounted on the front cover to allow independent adjustment of the switching threshold for each input circuit.
