Code Description Notes
PCOS00AKC0 PCOS00AKY0
PCOS00AKY0 /
PCOS00AKC0
(tech. leafl et code
+050003420 /
+050003410)
SMART KEY pro-
gramming key
and converter
Used for programming and servicing the controller. Simplifi es data transfer betwe-
en the controllers installed and a personal computer, thanks to the high-capacity
fl ash memory on which software applications, the BIOS and the variables log can
be stored. The controller is connected directly via the telephone connector using
the cable supplied, while to transfer data to a personal computer the PCOS00AKC0
converter is required. The device is powered either by the USB port on the PC or by
the controller, so no external power supply is necessary.
CVSTDUTLF0/CVSTDUMOR0
(tech. leafl et code
+050000590)
USB/RS485
converter
The optically-isolated converter allows interfacing an RS485 network to a personal
computer via the USB port. The converter is available in two versions:
• CVSTDUTLF0, equipped with a 6-pin telephone connector (RJ11);
• CVSTDUMOR0, equipped with a 3-pin connector.
PCOS0WUC20
(tech. leafl et code
+0500042IE)
Ultracap module
for pCO5+ built-
in driver
In case of power failures the module ensures a temporary power supply for the
driver only, for the time necessary to immediately close the electronic valves con-
nected (one or two). Using the valve lets you avoid having to install the solenoid
valve or the buff er battery kit in the refrigerant circuit.
EVD0000UC0
(tech. leafl et code
+0500041IE)
External Ultracap
module
Alternatively, the module, mounted on a DIN rail, can be connected to the Ultracap
module PCOS0WUC20. It can also be used in applications with drivers for elec-
tronic expansion valves not built into the controller (e.g. pCO5+ Small - EVD Evolu-
tion - external Ultracap module).
pCOE*
(tech. leafl et code
+050003265)
Expansion card
Increases the number of inputs/outputs on the controller. A maximum of 5 expan-
sion cards can be connected for each controller when running a tLAN protocol, or
15 expansion cards for each controller when running a CAREL or Modbus protocol.
Available models:
• PCOE000TLN0 - tLAN version (CAREL proprietary protocol);
• PCOE0004850 - RS485 version (CAREL supervisor protocol - Modbus® RTU).
EVD0000E*
(tech. leafl et code
+050004150)
Driver for elec-
tronic expansion
valve
The driver for electronic expansion valves with two-pole stepper motor is a control-
ler that manages refrigerant expansion in a refrigerant circuit. Versions with serial
ports for tLAN, pLAN and RS485 Modbus/CAREL are available. Alternatively, the
controller can operate in stand-alone mode.
CPY*
(manual code
+040000030)
Card for KUE CA-
REL humidifi ers
Allows managing an immersed electrode humidifi er and sharing the main parame-
ters through a CAREL/Modbus RS485 serial line.
Equipped with:
• all the inputs and outputs required to control the humidifi er completely and
independently;
• three LEDs to indicate: alarms (red), steam production (yellow), 24 Vac power
supply (green);
• can be connected to the CPY terminal (code CPYTERM*) or to the supervisor
network with Modbus® RTU or proprietary CAREL protocol.
PCOUMI2000
(tech. leafl et code
+050003210)
Interface for OEM
series humidifi ers
Allows checking the main parameters of humidifi ers for OEM made by CAREL di-
rectly from the pCO controller. The values measured by the sensors (high level,
supply water conductivity, power consumption sensor) are converted into signals
that are compatible with the inputs on the controller.
Note: The hardware simulator for the pCO5+ is available on request
(code CM00002030).
Important: pCO5+ controllers must only be used with the
dedicated simulator (P/N CM00002030), do not use pCO5+ controllers
with the pCO3 and pCO5 simulators.
