Introduction
The C-PRO MEGA f programmable controllers family is the right solution for refrigeration, ventilation and air
conditioning applications. Both in terms of controls, regulation and the user interface, the controller application
software is fully programmable, in a simple and intuitive way, thanks to the use of the UNI-PRO development
environment.
The C-PRO MEGA is available in a DIN rail version (see the pictueres below). It is available also in “open”
version only with plastic base for DIN rail mounting
By using the 8 relay outputs, it is possible to control various types of devices such as compressors, water
circulation pumps, defrosting elements, condensation or evaporation fans, cycle inversion valves, alarm
warning indicators etc.
The C-PRO MEGA is also equipped with 4 analog outputs 0,5-10 V, 0-20 mA or 4-20 mA.
The controller has 8 analog inputs :
- n° 2 for PTC probes / NTC probes / 0-5 V transducers / 0-10 V transducers / 0-20 mA transducers /
4-20 mA transducers
-
n° 6 for NTC probes / 0-20 mA transducers / 40-20 mA transducers
C-PRO MEGA is also equipped with 10 low voltage digital input (12-24 Vac/dc) for normally open contact.
All the parameters may be set from the user interface.
The display is 4 x 20 font alphanumeric LCD; the keypad has 9 keys and 6 signal LED ; the sealed case and the
open versions have neither display nor keypad and must be used in conjunction with a remote terminal.
The controllers have the following serial communication ports:
•
n° 1 optoinsulated RS-485 (always mounted on the controller) with EVCO or MODBUS
communication protocol
•
n° 1 not optoinsulated LocalCAN (always mounted on the controller)
• n° 1 optoinsulated RS-485 or n° 1 RS-232 (on request, not available on built-in or open
versions)
•
n°1 optoinsulated WideCAN (on request, available only on 128 KB memory version).
C-PRO MEGA has real time clock (always mounted on the controller).
With C-PRO EXP KILO, C-PRO EXP MEGA e C-PRO EXP GIGA, the I/O improvement is possible.
