2.1 Connections
Power supply:
The C-PRO Giga family is available with two different versions of power supply :
i. No optoinsulated internal switching 24Vac/dc version
ii. two separated inputs 12 Vdc + 12 Vdc version. With this version the following ports and
outputs are optoinsulated :
• the analogic output
• the RS-485 serial standard port
• the RS-485 (or RS-232) optional serial port
• the Wide CAN port
In order to ensure the optoinsulation of these outputs the controller must be supplied with two dc
power sources preferably electrically insulated, one from the other, for example by using an EVCO
power supplier “c-pro AL”.
The connection cables length must be 1 m, at the most.
Analogic input connections:
The C-PRO GIGA has two analogic inputs (universal named) suitable for the NTC, PTC, Voltage
(0-10V, 0-5V), Current (0-20mA, 4-20mA) sensors. The choice is automatically made by means of
the UNI-PRO development system or parameters. A Jumper must be removed only for the 0-10V
energized input (refer to the physical layout section and jumpers).
The C-PRO GIGA has six analogic inputs (configurable named) suitable for the NTC and Current
sensors (0-20mA, 4-20mA). The choice is automatically made by means of the UNI-PRO
development system or parameters. Note that the six inputs are divided into three pairs; each pair
must have the same input type.
The active probes may be fed by using the VDC terminals (see physical layout) with a stabilized
voltage of 12.5V (total maximum current <=200mA). The length of the analogic input connections
cables must be 3 m, at the most.
Digital input connections :
The C-PRO GIGA has ten low-voltage optoinsulated digital inputs (12-24Vac/dc) and two
additional high-voltage optoinsulated inputs (110-240Vac). To benefit from the optoinsulation
features, it's recommended to separate the digital input feed from the main power supply of the
controller. If the C-PRO GIGA is fed by using the C-PRO AL switching power supply, that can be
used to feed the controller and the digital inputs.
The length of the digital input connections cables must be 3 m, at the most.
Digital output connections :
C-PRO GIGA has 13 digital outputs. There are no groupings of terminals, therefore each individual
contact can be used for the declared specifications.
The length of the digital output connections cables must be 3 m, at the most.
Analogic output connections :
C-PRO GIGA has 4 optoinsulated analogic outputs (voltage or current). Both voltage and current
selection are achieved by using Jumpers (see section wiring layout) and parameters.
The length of the analogic output connections cables must be 3 m, at the most.
User interface connection :
The connection between C-PRO GIGA and the remote user interface has to be done with 4 wire
cable (better with two weaved couples).
