GENERAL CHARACTERISTICS

pCO is a microprocessor-based electronic controller compatible in both hardware and software terms with the pCO
by CAREL in compliance with the European RoHS directives, it provides a solution for many applications in the air-conditioning and
refrigeration sectors. It ensures absolute versatility, allowing specifi c products to be created to customer request.
pCO 3 runs the control program, and is fi tted with the set of terminals required for connection to the devices (compressors, fans...). The
program and the parameters are saved to FLASH-MEMORY and E
(without requiring a backup battery).
The program can be loaded using a PC (28.8 kbps and 115.2 kbps) or the special programming key.
pCO 3 also allows connection to the pLAN (pCO Local Area Network) and can be connected, as well as to other pCO
the other controllers in the pCO sistema and all the pGD family terminals. All the controllers in the pLAN can exchange information
(variables, digital or analogue, depending on the application software used) at high transmission speed. Up to 32 units can be
connected, including pCO controllers and terminals, so as to share the information effectively.
The connection to the supervisor/telemaintenance serial line, via the CAREL or Modbus™ communication protocol over the RS485
standard, is performed by inserting an optional serial board in the pCO
Other optional cards can be used to connect to a supervisor via standards other than RS485. Finally, the serial fi eld bus interface, using
the optional board, ensures connection to the fi eld devices controlled (for example: valves, pCOe I/O expansions, electronic valve
drivers...).
Versions available:
• SMALL, MEDIUM, LARGE, EXTRALARGE N.O. and EXTRALARGE N.C.;
• with or without Built-In terminal;
• with additional fl ash memory and optically-isolated pLAN;
• with or without solid state relay (SSR) digital outputs.
Note: the application software can be downloaded to the fl ash memory using the smart key PCOS00AKY0, see Fig. 6; or a PC using the
USB-485 adapter "CVSTDUTLF0" and the "WINLOAD32" program, to be ordered from CAREL.
Power supply
A Class II safety transformer with a minimum rating of 50 VA must be used in the installation to supply just one pCO
3
power supply to the µ pCO
to the other electrical devices (contactors and other electromechanical components) inside the electrical panel. If the secondary of the
transformer is earthed, make sure that the earth wire is connected to terminal G0. This is true for all the devices connected to the pCO
If powering more than one pCO
reference G0 must be maintained for all the boards).
If using the pLAN network and for further explanations and information, please refer to the CAREL manual pCO
