Pilz Automation Technology is launching the Decentralised Periphery PDP20 F 4 mag that meets PLe for series-connected safety switches. The new interface module PDP20 F 4 mag is suitable for series connection of safety devices such as tongue interlocks or magnetic safety switches, up to PLe (Performance Level 'e' of EN ISO 13849-1). This Performance Level is achieved through the use of test pulses generated by the PDP20 module being fed into the switch circuits and monitored.
The new interface module can be connected to dual-channel evaluation devices including Pilz PNOZsigma safety relays, PNOZmulti configurable safety relays and PSS safety PLCs. Up to four switches can be connected to each PDP20 module.
PDP20 interface modules can be easily installed in small enclosures close to the sensors that are to be connected. This ensures short signal paths for the sensor technology and a safe connection to the control cabinet. Pilz says that the PDP20 modules are suitable for any safety guard applications, including packaging machines and food processing machines.
Benefits of the new interface module are said to be:PDP20 modules are just 22.5mm wide and are protected to IP20. If enhanced ingress protection is required, Pilz also offers the IP67 PDP67 F 4 Code (390kB PDF) and PDP 67 F 8DI ION (520kB PDF).
