3 Technical characteristics
3.1 Connections
Power supply:
The C-PRO MICRO is powered by a 12 V AC supply. It may also be powered by a 12 V DC supply; in this
case, there is no option for controlling the fan cut-off modules. The maximum length of the power supply
connecting cables is 1 m.
Analogue input connections:
The C-PRO MICRO has two analogue inputs for NTC probes and two for NTC probes or for 0/4-20 mA or
0-5V ratiometric transducers. Selection is made by the UNI-PRO development system. The current transducers
may be supplied by means of the 12 V DC terminal (refer to the physical layout) with a non-stabilised voltage
equal to 12 V DC. The maximum length of the analogue input connecting cables is 3 m.
Digital input connections:
The C-PRO MICRO has 5 non-optoisolated digital inputs (clean contact). The maximum length of the digital
input connecting cables is 3 m.
Digital output connections:
The C-PRO MICRO has up to 6 electromechanical relay digital outputs. The maximum length of the digital
output connecting cables is 3 m.
Analogue output connections:
The C-PRO MICRO has 1 pulse modulation analogue output to drive the cut phase modules. The maximum
length of this analogue output connecting cables is 1 m.
The C-PRO MICRO has 2 voltage or current (optional) analogue outputs. The maximum length of these
analogue outputs connecting cables is 3 m. Optional analogue outputs are not available for the open models.
Remote terminal connections (IntraBus):
The connection between the C-PRO MICRO and the terminal is made using a 3 way cable. The maximum
length of the remote terminal connection cables is 1 m if using a DC supply from the controller; 30 m where the
wall-mounted keypad is supplied using a separate transformer.
Remote expansions connection (IntraBus):
The connection between the C-PRO MICRO and the I/O expansion units is made using a 3 way cable. The
maximum length of the remote I/O expansion units connecting cables is 1 m.
User interface connections (CAN):
The connection between C-PRO MICRO and the remote user interface is made using 2 way cable (better if it is
two weaves couples) plus possible ground.
The maximum length of the connection cables to the remote user interface depends of the CAN port baud rate.
- 1.000 m with 20.000 baud
- 500 m with 50.000 baud
- 250 m with 125.000 baud
- 50 m with 500.000 baud
The CAN port baud rate is settable by parameter.
