Siemens distributed 24 volt power supplies for use directly in the system

Siemens’s Industry Automation Division has developed two new 3-phase, 24 volt power supplies: the Sitop PSU300P and the Simatic ET200pro PS. These primary switched-mode 8 amp power supplies have the high IP65 degree of protection, and have been designed for distributed use directly in electrical installations. Sitop PSU300P is suitable for universal applications, whereas the Simatic ET200pro PS has been specifically designed for the Simatic ET200pro distributed I/O system, and supplies the electronic and load voltages to its system components. This power supply also has a special connector for looping through a 3-phase 380–480 AC voltage. Both new power supplies are suitable for use in ambient temperatures ranging between minus 25 and plus 55 degrees …

Robust speed sensor for conveyor belts in the primary industry

A new, compact, medium-resolution, belt speed sensor from the Siemens Industry Automation Division is suitable for any industrial application with belt-driven conveyor pulleys, for example in the primary industry. The lightweight, yet durable Sitrans WS100 is suitable in applications from -40 to +110 degrees Celsius (-40 to 164 degrees Fahrenheit). Typical applications include the mineral processing industry, in particular quarries or cement plants, with belt speeds up to 2 meters per second (392 feet per minute). The new sensor monitors the belt speed for input to an integrator, which calculates flow rate, total weight, belt load, and speed of bulk materials. Sitrans WS100 can be combined with a Milltronics BW100 or BW500 integrator or Siwarex …
