Siemens SIPLUS S7-1500 Series PLC CPU for Use with SIPLUS

When you need processor modules for harsh settings, try this Siemens PLC CPU bundle. It combines a pair of 1517H-3 PN CPUs that handle process automation and control applications. They're widely compatible with interfaces such as PROFINET or Ethernet and also support IP, IF and FO plug-in modules. As they withstand coolants and lubricants, the hardwearing units are a safe bet for demanding workplaces. You can use them on ships or at sea as they resist biologically, chemically or mechanically active substances. A conformal coating on the PCBs further boosts hardiness by preventing environmental hazards from causing electrical damage.

• Includes two 1m sync cables and four sync modules for linking your CPUs
• 5ms mains buffering helps bridge short-term power supply issues
• Reverse polarity protection prevents device damage if the polarity of your supply's reversed
• Six keys and a selector switch for easy control and configuration
• Superfast processing times up to 24ns mean you can count on swift operation

The CPUs in this bundle have a small amount of on-board memory which you can increase significantly by pairing them with SIMATIC memory cards up to 32Gb (243-4054).
