Brake control devices
Applications with safety brakes and holding brakes require reliable brake monitoring. This eliminates all potential hazards for the user – even when the drive is de-energised. With the stand-alone safety relay PNOZ s50, Pilz is offering an economical solution for controlling two safety brakes up to category PL e of EN ISO 13849-1.
On the safety relay PNOZ s50, temporary overexcitation is followed by voltage reduction, for which parameters can be set. Short ventilation times are achieved as a result, helping to make your application more energy-efficient. On the one hand, safe brake control enables rapid switching in emergency situations. On the other hand, it ensures slow, low-wearing switching in normal operation, thereby reducing maintenance requirements.
Safe and contactless braking – Your benefits
- Maximum safety up to PL e of EN ISO 13849-1 when two brakes are activated (holding brakes or safety brakes)
- Contactless technology with up to 4.5 A per safety brake enables short reaction times and a sustainable solution
- Wear-free braking
- High safety and low wear on the brake thanks to fast or slow shutdown of the power circuits
- Rapid diagnostics by means of display
- Manufacturer-independent brake control thanks to safe, digital inputs
Features of safety relay PNOZ s50
- Simple menu navigation using a rotary knob
- Setting parameters and diagnostic messages shown on the display
- Safety relay with two 2-pin, safe electronic digital outputs for 24 V DC, each with 4.5 A
- Reduced cycle times through temporary overexcitation with subsequent voltage reduction
