7/20/2011 - Pilz Automation Technology added base units for its PNOZmulti Mini range of configurable safety relays. These modular, expandable base units enable fast, easy connection of communication and safe link modules, as well as contact expansion modules.
The PNOZ mm0.1p and PNOZ mm0.2p base units are now available in addition to the existing PNOZ mm0p non-expandable base unit; and these can be expanded using safe outputs (using PNOZ Sigma), communication modules (Ethernet TCP/IP or Modbus TCP), and/or “safe link” modules which increase safety input capacity and safety-related data transmission between interconnected base units. The base units have been launched with two safe link options – added or built-in. Base unit PNOZ mm0.1p is for use with additional safe link module PNOZ mml1p to interconnect multiple base units, providing distributed transmission of safety-related control data between base units across a machine; this enables sophisticated zoning for harmonious safety and productivity. Base unit PNOZ mm0.2p achieves exactly the same, but with an integrated safe link interface in the same 45mm housing, providing yet more panel space saving.
The PNOZ mm0.1p and PNOZ mm0.2p base units are expandable on the left hand side by using up to 4 safe link modules PNOZ mml1p multi-Link (for interconnecting multiple PNOZmulti’s) or up to 4 PNOZ mm12p (for connection of the distributed periphery PDP67 modules), and by using communication modules PNOZ mmc1p / PNOZ mmc2p (for Ethernet TCP/IP and Modbus TCP comms). Output expansion is achieved on the right hand side using the existing range of Pilz’s PNOZsigma expansion modules (PNOZs7 – s11), increasing the number of relay contacts available.
For applications requiring decentralised wiring of safety sensor inputs (such as light curtains, mechanical interlock switches, coded magnetic switches, etc.) the new safe link module PNOZ mml2p can be used with either of the new PNOZmulti Mini bases to connect to new IP67 input modules known as Pilz Distributed Periphery PDP67. Up to sixteen PDP67 modules can be connected to a single base via four multi link modules, allowing up to 64 extra safety functions to be connected to a single base in a decentralised manner. Each connected safety sensor can be addressed and diagnosed separately, removing the age-old issue of fault-masking encountered with traditional series hardwiring of sensors. As a result, all safety functions can be monitored not just safely, but directly in the field.
The safe link modules are designed up to PL e in accordance with BS EN ISO 13849-1 and SIL CL 3 in accordance with BS EN 62061.
The base units are easy to configure using Pilz’s proven software tool, the PNOZmulti Configurator. This means base units are configured rather than wired, resulting in less wiring and reduced installation times.
The PNOZmulti Mini is the latest addition to the PNOZmulti range of multifunctional control systems from Pilz. With a width of just 45 mm, the PNOZmulti Mini is extremely compact and therefore provides panel space saving in all areas of manufacturing and process control, including CNC machining centres, machine tools, presses, packaging machines, injection moulding machines, automotive robot cells, and metal processing.
PNOZmulti Mini base units provide 20 safe inputs. Up to 8 of these inputs can be set as standard outputs in the PNOZmulti Configurator. The unit also offers 4 safe semiconductor outputs and 4 test pulse outputs.
PNOZmulti Mini develops upon the existing benefits of PNOZmulti, which include multi-functionality, easy configuration, compact design, simple diagnostics through integrated display, and up to 40% reduction of time and costs in all engineering phases.
