Safety relay PNOZ s50 for safe brake control

Applications that involve safety brakes and holding brakes necessitate dependable brake monitoring to ensure maximum user safety, even when the drive is not energized. Pilz offers an economical solution for governing two safety brakes up to category PL e of EN ISO 13849-1 in the form of the stand-alone safety relay PNOZ s50. With this relay, parameters can be set for temporary overexcitation followed by voltage reduction, resulting in short ventilation times for better energy efficiency. On the one hand, the safe brake control enables speedy switching in case of emergency. On the other hand, the relay ensures slow and low-wearing switching during normal operations, 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

Application on gravity-loaded axes

The safety relay PNOZ s50 can be used in many application areas to safely control brakes. For example, in stage technology; on machine tools; on press brakes; on packaging machines; in test stand technology; in materials handling technology or in energy and environmental technology.

Machines with Z-axes

The following machines have Z-axes, for example:

  • Loading and unloading gantries
  • Palletisers
  • Milling machines
  • Robot axes
  • Lifting devices
  • Machines with valves/pneumatics/hydraulics
  • Winches

Application in stage technology on winches

In some applications, it is necessary to safeguard a second brake alongside the holding brake. In the field of stage technology, for example, winches are operated with a dual brake. The PNOZ s50 can control two powerful brakes safely without the use of contacts.

Application on scissor tables

Scissor tables are lifting devices with gravity-loaded axes. They are used during final assembly in automotive production, for example. When employees are working on vertical axes, various requirements from the Machinery Directive apply.
