On the safety relay PNOZ s50, temporary overexcitation is followed by voltage reduction, for which parameters can be set. The resulting short ventilation times help 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. Applications with safety brakes and holding brakes require reliable brake monitoring. This eliminates all potential hazards for the user – even when the drive is in a de-energised state. 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. http://www.pilz.com

The safe line monitoring 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. http://www.pilz.com

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. http://www.pilz.com

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!

The Long-Range version PSENvip R LR is the first and only protection system for press brakes with a protected area of up to 18 metres. This makes it ideal for monitoring special purpose presses such as tandem presses, for example. The installation of PSENvip R LR on existing presses is quick and easy: the transmitter remains the same, you only have to swap the receiver. Monitor your tandem press with just one protection system; there’s no need to combine a mobile protection system and light curtains. http://www.pilz.com

With the Long-Range version you also have a hot-pluggable protection system: If you place two press brakes next to one another, you can simply remove the transmitter and receiver in the centre. The transmitter from machine 1 then works with the receiver from machine 2 – without having to restart! You thus avoid unnecessary downtimes with PSENvip R LR. Furthermore, the Long-Range version of the PSENvip is convincing thanks to its usual high level of robustness.

Safe radar sensors are used where optoelectronic sensors reach their limits: rugged environments, such as outdoors or in material processing for example, can be monitored safely using PSENradar. That’s because radar technology (FMCW: frequency modulated continuous wave) ensures high availability even where there are external influences such as dust, dirt, rain, light, sparks or vibrations. http://www.pilz.com

The safe radar sensor PSENradar, in conjunction with the configurable small controller PNOZmulti 2, offers a safe, complete solution for protection zone monitoring – including conformity assessment for the plant or machine. The underlying volumetric monitoring with a frequency of 24 – 24.25 GHz can be used up to SIL 2, PL d and Category 3, which is often a requirement in robot applications. The complete solution also has additional interfaces, such as Ethernet and Profisafe, so making it easy to use the safety radar sensor in retrofit applications. http://www.pilz.com

The appropriate protection zone can be defined for each sensor, based on the size of the area to be monitored. This depends on the positioning, installation height and inclination of the sensor. A warning zone can also be configured in addition to the protection zone. If a person violates the warning zone, this may be signalled by an optical signal, for example. This way, productivity of the plant can always be kept at a high level.
