Feature
c . pCO sistema guarantees highly reliable control of air conditioning and refrigeration units , while at the same time allowing maximum adaptability for differentiation both in terms of appearance and function .
Several models are available based on the number and type of inputs / outputs , with or without built-in terminal . The plastic enclosure with DIN rail mounting guarantees high mechanical protection of the board and reduces the risk of electrostatic discharges , while also housing an optional built-in user interface with semi-graphic LCD and six LED backlit buttons .
The c . pCO family of programmable controllers is the latest evolution of CAREL control technology , featuring unprecedented communication capabilities . With a multitasking operating system and the adoption of standard protocols , local and remote connectivity are the key innovations in the new c . pCO sistema . The c . pCO controller features specific new functions to improve the efficiency of HVAC & R systems :
• Connectivity : The c . pCO family controllers are the evolution of the pCO5 +, with unprecedented connectivity . They offer even the most demanding designers up to two built-in Ethernet interfaces , five serial lines , three of which built-in and configurable in terms of protocol ( CAREL or Modbus ) and type ( FieldBus or BMS ), and two optional ports , configurable in terms of protocol ( Modbus , BACnet , CAREL , CANbus , Konnex , LonWorks ) and physical layer ( RS485 , Ethernet , CAN , Konnex , FTT-10 ). Standard USB ‘ host ’ and ‘ device ’ ports are available for programming the c . pCO using a standard USB pen drive , or via a direct connection to a PC without needing an additional external serial converter .
• Operating system : The multitasking operating system ensures optimum use of system resources , extends the data types that can be used to develop the application ( 32-bit floating point numbers ), increases the application program execution speed and allows independent management of communication protocols .
• I / O flexibility : The CAREL-proprietary ASIC chip used means all c . pCO controllers feature universal I / O channels that can be configured via software as analogue inputs , digital inputs and analogue outputs .
• High efficiency : Built-in EVDEVO drivers for controlling electronic expansion valves with Ultracap technology ensure that the stepper electronic expansion valve closes in the event of power failures .
THE MINI MODEL c . pCOMini is a compact programmable controller in just 4 DIN
