Carel steps up the pace

Carel has extended its range of programmable controllers with the addition of the pCO5+ HS (High Speed).
The new controller is said to improve performance both in terms of application times (start-up and cycle) and upgrade speed. Native integration of the USB port further simplifies maintenance: the data logger files saved on the controller can be simply and quickly copied to a USB flash drive or PC, for detailed analysis. In addition, the calculation speed of the unit means it can respond more quickly and precisely to variations in the main unit input values (temperature, pressure, humidity, etc.).
The pCO5+ HS comes with two built-in serial interfaces, two expansion slots and two USB ports. The controller also features a wide range of optional cards for managing the communication protocols typically used in HVAC/R (Modbus, Carel, BACnet, LonWorks, KNX, HTTP, SNMP). Communication with Carel apps can also be implemented using 1tool.
Energy saving
The pCO5+ HS is available in a version with two built-in electronic expansion valve drivers and an optional Ultracap module, for integrated energy saving management.
Backwards compatibility 
The new model is compatible with the full range of pCO3 and pCO5 controllers in terms of both hardware (pin-to-pin compatible) and software. Carel software (1tool, pCOManager, SmartKey Programmer) can be used to load the binary files onto the new pCO5+ HS.
Carel says the improved performance of the pCO5+ HS makes it suitable for:
  •       Chillers (with screw or centrifugal compressors)
  •       Process chillers (where it is important to guarantee constant temperature and humidity)
  •       Data centres
