pCO5+ Programmable controller

pCO5+ Programmable controller one response to the multiple current and future demands of the HVAC/R market.pCO5+ comes in 10 different sizes, guaranteeing an excellent solution for all HVAC/R applications.

Flexibility

Up to 10 universal channels, each configurable as an input or output:

• NTC, PTC, PT100, PT500, PT1000 probe, 0/1V, 0/5V, 0/10V, 0/20 mA, or 4/20 mA, 

• voltage-free digital input (standard and fast) 

• analogue output (0/10V and PWM)

Carel has developed a proprietary chip using ASIC technology (ApplicationSpecific Integrated Circuit), ensuring greater system flexibility as manufacturers can use the same size board for different applications. The Carel ASIC increases the resolution of analogue inputs for more accurate calculations, for example when converting refrigerant temperature, imperial/metric readings, seasonal performance factor (SPF) and coefficient of performance (COP)…

pCO5+ comes in 10 different sizes, guaranteeing an excellent solution for all HVAC/R applications.

Connectivity

Up to 7 communication ports available, with the most commonly-used protocols in HVAC/R applications, for complete system management: pLAN, 1 BMS1, BMS2, FieldBus1, FieldBus2, USB host, USB device.

pLAN

RS485 multi-master communication port to connect terminals and manage distributed intelligence

USB

USB “Host” and “Device” ports for communication with standard USB pendrives or direct connection to a PC for programming and commissioning without requiring serial converters

BMS

One RS485 BMS port, always included as standard, also available in the optically isolated version; this can be configured with CAREL and Modbus RTU protocols.A vast range of optional cards - which can also be installed during commissioning rather than in the factory - is available to interface with the most commonlyused communication standards, such as Modbus® (RTU and TCP/IP), BACnet™ (MS/TP and IP), SNMP, LonWorks®, Konnex® and Johnson METASYS®. 

Fieldbus

One RS485 FB port, always included as standard, also available in the opticallyisolated version; this can be configured with CAREL and Modbus RTU protocols. 

This standard port can be used to manage smart actuators, such as inverters, EC fans, 

variable flow-rate pumps, etc. without requiring an additional card.A vast range of optional cards - which can also be installed during commissioning rather than in the factory - is available to interface with the most commonly-used field bus standards.

Energy saving

Up to 2 integrated EVDEVO drivers for managing two Independent EX

V electronic expansion valves, meaning less wiring and space occupied. The Ultracap module can also be installed without increasing the physical dimensions of the pCO5+; this module guarantees the valves close in the event of power failures, eliminating the need for the solenoid valve that would otherwise be needed to close the circuit.

The Ultracap module, exploiting ELDC (Electric Double Layer Capacitor) technology, represents a fast, reliable and environmentally-friendly solution for closing the electronic expansion valve in the event of power failures 

Cloud based

Possibility to perform actions via web, such as read and write unit variables, update the 

application on the board, and Webserver to browse custom HTML pages, send emails

Backward compatibility

pCO5+ is compatible with the two previous generations of the pCO family: pCO5and 

pCO3. pCO5+ includes a BIOS that emulates the functions of the pCO3and pCO5, thus allowing manufacturers who currently use pCO3or pCO5to replace these with a pCO5+, reusing the exact same software without needing to edit or recompile.

Fast

emergency closing is completed quickly and is guaranteed in all conditions.Following emergency closing, when the capacitors are completely discharged, the Ultracap module takes just 5 minutes to recharge and become operative again (in practice, this is the same delay for restarting a compressor after a blackout).

Reliable

Ultracap has been designed to ensure 10 years’ operation, without needing periodical checks or battery replacement, at a very competitive price.

Environmentally-friendly

a lower environmental impact than lead battery systems, both in terms of construction and waste disposal requirements
