- with 4 + 4 digits custom LED display (with function icons) and with a 6 buttons (with preset functions) keyboard made of
silicone rubber integrated in the controller, hereinafter also called “built-in LED versions”
- blind (they can be used for example with an user interface such as Vgraph, Vtouch, Vroom or Vcolor), hereinafter also
called “blind versions”.
c-pro 3 kilo and c-pro 3 kilo+ are available in the following versions:
- with 128 x 64 pixel single colour LCD graphic display (black with rearlighting through white LEDs) and with a 6 buttons (with
preset functions) keyboard made of silicone rubber integrated in the controller, hereinafter also called “built-in LCD versions”
- with 4 + 4 digits custom LED display (with function icons) and with a 6 buttons (with preset functions) keyboard made of
silicone rubber integrated in the controller, hereinafter also called “built-in LED versions”
- blind (they can be used for example with an user interface such as Vgraph, Vtouch, Vroom or Vcolor), hereinafter also
called “blind versions”.
Some integrate an unipolar stepper electronic expansion valves driver.
The I/O expansions are available in blind version.
Through the development environment UNI-PRO 3 (to order separately) it is possible to realize the application software and through a
commun USB cable it is possible to program the controllers.
The devices look in case 4 DIN modules; installation is in electrical panel, on DIN rail.
Through a common USB peripheral it is possible to make the upload and the download of the configuration parameters.

Power supply, RS-485 port with Modbus slave communication protocol and CAN port
Terminal Meaning
V≅ +
V≅ -
power supply controller (12 VAC in c-pro 3 micro and in c-pro 3 micro+, 24 VAC / 20... 30 VDC in c-pro 3 kilo and in
c-pro 3 kilo+); if the controller is powered in alternating current, connect the phase
power supply controller (12 VAC in c-pro 3 micro and in c-pro 3 micro+, 24 VAC / 20... 30 VDC in c-pro 3 kilo and in
c-pro 3 kilo+); if the controller is powered in alternating current, connect the neutral
A / + terminal 1 of the transceiver RS-485 port
B / - terminal 0 of the transceiver RS-485 port
CAN + signal + CAN port
CAN - signal - CAN port
The maximum length of the connecting cables is:
- 100 m (328 ft) for the power supply
- 1,000 m (3,280 ft) for the RS-485 port; also look at the Modbus specifications and implementation guides manual
(the document is available on the internet site www.modbus.org).
The maximum length of the connecting cables of the CAN port depends on the baud rate of the CANbus communication, as
follows:
- 1,000 m (3,280 ft) with baud rate 20,000 baud
- 500 m (1,640 ft) with baud rate 50,000 baud
- 250 m (820 ft) with baud rate 125,000 baud
- 50 m (164 ft) with baud rate 500,000 baud.
Protect the power supply with a fuse rated 2 A-T 250 V.
If the controller is powered in direct current, it will be necessary to respect the polarity of the power supply voltage.
In case of connection in a network:
- for the devices powered at 12 VAC, the power supply of the devices in the network must be galvanically isolated one another
- for the devices powered at 24 VAC, it is necessary the phase powering the device is the same powering the remaining
devices in the network
- for the devices powered at 20... 30 VDC, it is necessary to recpect the polarity ot the power supply voltage of all the devices in
the network.
Connect the RS-485 port using a twisted pair.
