3 Technical characteristics
3.1 Connections
Power supply:
The C-PRO KILO is powered by 24 VAC. It can also be powered using DC supplies with outputs between 20
and 60 VDC; in this case, it is not possible to control the fan and phase chopping modules. The maximum
length for the power supply connecting cables is 1 m.
Connecting the analogue inputs:
The C-PRO KILO has three analogue inputs for NTC sensors, and two for NTC sensors/0-20 mA
transducers/4-20m A transducers/0-5 V ratiometric transducers (on request). Selection is implemented by the
UNI-PRO development system. The 0-20 and 4-20 mA transducers may be powered from the +12 V terminal,
the 0-5 V ratiometric transducers from the +5 V terminal (see the physical layout). The maximum length for the
analogue input connecting cables is 3 m.
Connecting the digital inputs:
The C-PRO KILO has 7 non-optoisolated digital inputs (clean contact). The maximum length for the digital
input connecting cables is 3 m.
Connecting the digital outputs:
The C-PRO KILO has a maximum of 7 digital outputs to electromechanical relays (two can be SSR). The
maximum length for the digital output connecting cables is 3 m.
Connecting the analogue outputs:
The C-PRO KILO has 1 pulse analogue output for driving the phase chopping modules. The maximum length
for the connecting cables for this type of analogue output is 1 m.
The C-PRO KILO also has 2 voltage or current analogue outputs (optional). The maximum connecting cable
length for these analogue outputs is 3 m. Optional analogue outputs are not available for the open case models.
Connecting the remote terminals (IntraBus):
The connection between the C-PRO KILO and the user terminal is made using a 3 way cable. The maximum
length for remote terminal connecting cables is 1 m if powered by DC current from the controller; 30 m in the
case of a wall-mounted keypad powered by a separate transformer.
Connecting the remote expansion units (IntraBus):
The connection between the C-PRO KILO and the I/O expansion units is made using a 3 way cable. The
maximum length for the remote I/O expansion units connecting cables is 1 m.
User interface connections (CAN):
The connection between C-PRO KILO 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.
