Configurable Control Systems PNOZmulti 2 – Base Units
July 27, 2020
The basis for your application.
Multifunctional, freely configurable and tailor-made: the base units PNOZmulti 2 are used in virtually every area of plant and mechanical engineering. PNOZmulti can be used to monitor safety functions safely and to perform standard control functions economically.
All the necessary functions are created on the PC using the ingeniously simple configuration software PNOZmulti Configurator. The completed configuration is loaded into the base unit via a USB port. A further benefit is the exchangeable program memory. The base unit PNOZ m B1 uses a USB stick; the PNOZ m B0 uses a chip card.
Safe firing and more with the small controllers PNOZmulti 2 
The safe small controllers PNOZmulti 2 have a new base unit for safe control and monitoring of furnaces. The base unit is supported from Version 10.12 of the software tool PNOZmulti Configurator and is equipped with a burner element (function block), which emulates the advanced functionality of a flexible, configurable electronic automatic burner control system. As a result it is easy to configure a large number of burner applications.
These include different burner types, for example master or slave burners, direct or indirect ignition, low or high temperature mode and many more. The software element has been tested and certified in accordance with the relevant European standards, including EN 298 and EN 50156, plus the North American standard NFPA 85/86. The base unit can be used on thermoprocessing and steam boiler plants.
Your application advantages:
- Flexible and safe design for your furnace
- Saves a lot of time when planning and engineering, as even complex safety applications can be implemented simply and quickly with just one small controller
- Ability to connect to numerous automation environments and communication systems
- Maximum safety due to tested, certified hardware and software elements
