High energy efficiency due to reduced cycle times

To improve the cycle times, and thus the plant’s energy efficiency, Pilz uses pulse width modulation to reduce the voltage. Contactless and therefore non-wearing technology in the 24/48 Volt DC range is also new. It reduces the reaction time in conjunction with the brake, significantly improving protection for operating personnel.  

Depending on the safety requirement, PNOZ s50 can also be combined with the safe motion solution PMCprotego DS from Pilz, in which case it also provides a safe brake test (SBT). Just like other developments in the PNOZsigma product range, PNOZ s50 has a rotary knob for easy navigation through the menu and for setting the required parameters. This saves time during setup, as neither a PC nor software is required.

Vertical axes present a safety challenge

Failure of the braking device due to wear and tear plus failure of the energy supply are two of the main reasons for suspended loads falling or crashing in an uncontrolled manner. The safety relay PNOZ s50 makes an important contribution towards the management of risks on vertical axes. Typical application areas for vertical axes are loading and unloading gantries, machine tools, lifting devices and stage technology.

The new safety relay PNOZ s50 can safely control two powerful brakes simultaneously without the use of contacts

The safety relay PNOZ s50 with emergency stop function is designed to control holding brakes or safety brakes in the 24/48 Volt DC range on vertical axes up to PL e of EN ISO 13849-1 or SIL CL 3 of EN/IEC 62061.
