The innovative PNOZelog range of compact, electronic safety relays from Pilz Australia , combines the experience of electromechanical safety relays with the advantages of modern electronics.

PNOZelog safety relays allow users to reliably monitor up to four safety functions. Wear-resistance, safety and long service life ensure that it is cost-effective to use.

The logic operations of these safety relays reduce wiring costs while the expanded diagnostics increase the availability of the machine. Power-up tests, self-checking and runtime tests also guarantee maximum safety.

PNOZelog safety relays are specifically formulated to monitor the following safety functions:

  • E-STOP
  • Safety gate
  • Light grids
  • Safety mats
  • Two-hand
  • Time delay 
The electronic structure of the PNOZelog safety relays means they are non-wearing and  suitable for use in difficult environmental conditions.  Being non-wearing is particularly important in applications with recurring functions such as the monitoring of light grids and safety switches. Mobile applications in particular benefit from the unit's resistance to difficult environmental conditions.

Other features and benefits of the PNOZelog safety relays include:

  • Simple logic connections (AND/OR) mean less wiring
  • High availability thanks to extended diagnostics 
  • Consistent use of semi-conductor technology means no maintenance is necessary, so there are no malfunctions due to contact welding, contamination, bounce or burning. 
  • Continuous self-checks provide the highest level of safety; fault detection is not linked to the on/off cycle
  • Long service life, even with frequent operations or cyclical functions
  • Safe switching operations even on the smallest of loads
  • Fast commissioning; plug-in terminals with cage clamp and screw connection mean that no additional tools are required 
  • The PNOZelog product range meets the requirements of Category 4 in accordance with EN 954-1. For international use, PNOZelog also has approvals in accordance with BG, UL, ULc, CCC and Gost.
