devices with AWG20/22 shielded cable is 500 m.
Note:
• J10 can only be connected to one terminal (pCOT, pCOI, pGD0, pGD1) or two terminals when the backlighting for the display is
not activated.
• Except PGD0 and PGD1 terminals, the other terminals should be always powered with separate power supplies.
• The 21 Vdc available at +Vterm (J24) can be used to power an external terminal as an alternative to the one connected to
terminal J10, with maximum current 1.5 W.
VERSION WITH ELECTRONIC EXPANSION VALVE DRIVER
The pCO5 Medium size features an optional new integrated solution: the version with built-in EVD EVO driver, single or twin. The
driver card is housed on the pCO5 in the socket provided for the inputs / outputs on the Large size board, hence the reason it’s
only available on the pCO5 Medium (not Small, Large, nor ExtraLarge) and doesn’t require an external power supply..
The built-in driver replicates all the hardware and functions logical of the “EVD Evolution TWIN” driver, i.e. independently controls
one or two electronic expansion valves with two-pole stepper motors. The only diff erence between the two versions is the
absence of the relay output. For details on the valve control logic, setup and installation see the EVD EVO manual
(code + 0300005EN).
In the same way as EVD EVO, on the pCO5 the integrated driver is available in the CAREL and Universal versions. The “Universal”
models are used to control both CAREL electronic expansion valves and products made by other manufacturers (see the table
below), while the CAREL models only manage CAREL valves.

This version of pCO5 Medium with built-in EvdEVO driver can be integrated with the energy storage module (PCOSC20), made
using special capacitor technology called Ultracapacitor, so as to ensure the electronic valve closes in the event of power failures.
The module only powers the driver and not the pCO

this in integrated into.
S
erial communication and programming
Communication between the pCO5 and its built-in EVD EVO driver is managed internally using the Fieldbus2 serial port. The
FieldBus2 serial port (J26) is however electrically insulated from the driver serial line: this ensures that in the event of external faults
on the line connected to FBus2, the internal driver can continue working independently and correctly.
The driver can only be confi gured exclusively using the pCO5 application developed in 1Tool, no external displays are available for
the EVD EVO.
The 1tool development environment features a module for managing the EVD EVO: the same module can be used to manage the
internal driver, as if it were managing an external EVD EVO connected to the FBus2 port.
