Safety relays

The safety relays PNOZ monitor safety functions such as E-STOP, safety gates, light barriers, light grids, two-hand controls, pressure sensitive mats, speed, standstill and much more too. Every day, PNOZ safety relays prove themselves in millions of applications worldwide. In 1987 Pilz patented the first emergency stop relay to protect man and machine. That was a milestone in safety technology. PNOZ safety relays quickly progressed to be the world’s most commonly used safety relays. The PNOZ brand is now synonymous with safety relays. PNOZ – The original! Continual development led from these simple devices to the configurable small control systems PNOZmulti, the worldwide safety standard for machinery.

With monitoring relays, the priority is the protection of persons and the machinery against insulation faults, residual voltages, overvoltage, overcurrent, overload, temperature overload as well as monitoring standstill and true power. Significantly reduce hazardous situations for man and machine, while at the same time increasing the service life of your plant. Save costs and guarantee an efficient production cycle. All this by using monitoring relays!

These monitoring relays are multifunctional and can be applied universally, covering a wide range of applications. You can use PMD monitoring relays to meet the requirements of IEC 60204-1 for the safety of electrical equipment on your machines.

The safe line inspection device PLIDdys provides safe power-up on two-wire connections, providing maximum safety on long cable routes. With PLIDdys, unintended power-up or plant start-up can be excluded in the event of an error. This is particularly beneficial on interlinked plants or on plant sections distributed over a wide area, which may not always be clearly visible.

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.
