Read these instructions carefully before installing and using the control-

ler and follow all additional information for installation and electrical

connection; keep these instructions close to the controller for future

consultations.

The controller must be disposed according to the local

legislation about the collection for electrical and electronic

equipment.

- 3 non optoisolated communication ports of which 1 CAN port with

CANbus communication protocol, 1 RS-485 port with Modbus

master / slave communication protocol (configurable via application

software) and 1 programming and debugging port.

Through the I/O expansion

c-pro 3 EXP hecto

c-pro 3 EXP hecto+

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 pro-

gramming kit EVIF20TUXI (to order separately) it is possible to program

the controller.

The devices look in case 4 DIN modules.

Installation is in electrical panel, on DIN rail.

Through the programming key EVKEY10 (to order separately) it is also

possible to make the upload and the download of the configuration

parameters.

ducts, etc.), devices provided with big magnetos (big speakers, etc.),

locations subject to direct sunlight, rain, humidity, dust, mechanical

vibrations or bumps

POWER SUPPLY

TERM. MEANING

V≅ power supply controller (24 VAC / 20... 40 VDC)

If the controller is supplied in direct current, one will not have to respect

the polarity of the power supply voltage.

5.2 Plugging in the termination of the RS-485 port

Position micro-switch 1 on position ON to plug in the termination of the

RS-485 port.

5.3 Polarizing the network of the RS-485 port

CAN port.

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.

sonde PTC / NTC / Pt 1000 / trasduttori 0-20 mA / 4-20 mA / 0-5 V

raziometrici / 0-10 V

- 5 ingressi digitali non optoisolati (contatti puliti)

- 3 uscite analogiche di cui 1 non optoisolata di tipo PWM e 2 non

optoisolate configurabili via parametro di configurazione per segnale

di tipo 0-20 mA / 4-20 mA / 0-10 V

- 6 uscite digitali (relè elettromeccanici) di cui 5 da 5 A res. @ 250 VAC di

tipo SPST e 1 da 8 A res. @ 250 VAC di tipo SPDT

protocollo di comunicazione CANbus, 1 di tipo RS-485 con protocollo

di comunicazione Modbus master / slave (configurabile via software

applicativo) e 1 per la programmazione e il debug.

Attraverso l’espansione di I/O

c-pro 3 EXP hecto+

è possibile incrementare il numero di ingressi e di uscite.

Attraverso l’ambiente di sviluppo UNI-PRO 3 (da ordinare separatamente)

è possibile realizzare il software applicativo e attraverso il kit di program-

mazione EVIF20TUXI (da ordinare separatamente) è invece possibile pro-

grammare il controllore.

I dispositivi si presentano in contenitore 4 moduli DIN.

L'installazione è prevista in un quadro elettrico, su guida DIN.

Attraverso la chiave di programmazione EVKEY10 (da ordinare

separatamente) è possibile eseguire l'upload e il download dei parame-

tri di configurazione.
