2 INTRODUCTION
2.1 Introduction
c-pro 3 micro+ and c-pro 3 kilo+ are two families of programmable
controllers.
The families are available in the version:
• with 128 x 64 pixel single colour LCD graphic display (black with
rearlighting through white LED) and with a 6 buttons (with preset
functions) keyboard made of silicone rubber integrated in the control-
ler, hereinafter also called built-in LCD versions (not available in
c-pro 3 micro+)
• with 4 + 4 digit custom display (with function icons) and with a 6
buttons (with preset functions) keyboard made of silicone rubber inte-
grated in the controller, hereinafter also called built-in LED versions
• blind (usable for example with an user interface such as Vgraph,
Vtouch, Vroom or Vcolor) hereinafter also called blind versions.
The controllers have got:
- real time clock
- 9 analog inputs of which 6 configurable via configuration parameter
for PTC / NTC / Pt 1000 probes / 0-20 mA / 4-20 mA / 0-5 V ratiometric
/ 0-10 V transducers and 3 configurable via configuration parameter
for PTC / NTC / Pt 1000 probes
- 9 optoisolated digital inputs at 24 VAC / DC of which 7 at 50 / 60 Hz
and 2 up to 2 KHz
- 6 non optoisolated analog outputs of which 2 configurable via con-
figuration parameter for PWM / 0-10 V signal, 2 configurable via con-
figuration parameter for 0-20 mA / 4-20 mA / 0-10 V signal and 2 for
0-10 V signal
- according to the model:
• 9 digital outputs (electromechanical relays) of which seven
3 res. A @ 250 VAC SPST outputs and two 3 res. A @ 250 VAC SPDT
outputs
• 9 digital outputs of which seven 3 res. A @ 250 VAC SPST electrome-
chanical relays and two solid stare relays (24 VAC/DC, 0.6 A max.)
• seven 3 res. A @ 250 VAC SPST digital outputs (electromechanical re-
lays) and an unipolar stepper electronic expansion valves driver
- 4 non optoisolated communication ports of which 1 USB OTG port
(for programming and debugging), 1 CAN port with CANbus com-
munication protocol, 1 RS-485 port with Modbus master communica-
tion protocol and 1 RS-485 port with Modbus slave communication
protocol.
Through the I/O expansion c-pro 3 EXP micro+ or c-pro 3 EXP kilo+ it
is possible to increase the number of inputs and outputs.
Through the development environment UNI-PRO 3 (to order separately)
it is possible to realize the application software and through the con-
necting cable 0810500018 (2 m, 6,561 ft long) or 0810500020 (0.5 m,
1.640 ft long), to order separately, it is possible to program the control-
ler.
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.

Hardware manual of
c-pro 3.

5.5 Additional information for electrical connection
• do not operate on the terminal blocks with electrical or pneumatic
screwers
• if the controller has been moved from a cold location to a warm one,
the humidity could condense on the inside; wait about an hour be-
fore supplying it
• test the working power supply voltage, working electrical frequency
and working electrical power of the controller; they must correspond
with the local power supply
• connect the controller to the other devices using a twisted pair
• disconnect the local power supply before servicing the controller
• do not use the controller as safety device
• for repairs and information on the controller please contact EVCO
sales network.

necting kit CJAV19 (wired female Micro-Fit connectors for
c-pro 3 mi-
cro+, to order separately) and the connecting kit CJAV20 (female ex-
tractable spring terminal blocks pitch 3.5 mm (0.137 in) for
c-pro 3

To program the controller one suggests to use the connecting cable
