Space-saving safety controller
10 August 2009
Pilz Automation Technology has introduced the PNOZmulti Mini multifunctional configurable safety controller for applications up to BS EN ISO 13849-1 Ple and BS EN 62061 SIL 3. The unit is a space-saving 45mm wide, features all of the usual safety monitoring functions of the established PNOZmulti and has the additional benefit of an integral LCD display for status information and diagnostic messages. Together with the new low-cost 'lite' licence for the PNOZmulti Configurator Software, Pilz now offers a cost-effective ‘start-up’ option for applications requiring from three safety functions upwards.
The first PNOZmulti Mini model, the PNOZmm0p, is multifunctional, program configurable and designed to replace from three to five traditional safety relays. The controller performs monitoring of safety functions such as Emergency Stop Switches, Guard Interlock Switches, Safety Sensors, Light Curtains and other safety devices, plus the same unit can execute standard (i.e. non-safety) control functions.
Even with its more compact design, the PNOZmm0p offers the following: 20 safe digital inputs; 4 safe semiconductor outputs (capable of being configured up to SIL3, PLe) and a USB configuration interface. With the integral LCD display for showing status information and diagnostic messages, the unit defines a new level of operator convenience.
A major advantage of the PNOZmulti Mini is the highly intuitive graphical Configurator Software which is used to create the Application Program. The Program is then downloaded from the user’s computer directly to the PNOZmulti Mini. For serial production, the Application Program can also be stored and transferred via the removable chip card. The PNOZmulti Configurator Software is used for the whole range of PNOZmulti products, but users now have the option to purchase an economically priced 'lite' licence that has been released specifically for use only with the PNOZm0p (PNOZmulti) and PNOZmm0p base units. Pilz believes that this makes the PNOZmulti Mini an exceptionally economic option, particularly for first-time users.
