DIGITAL OUTPUTS

Digital outputs 9 and 10 (electromechanical relays).

Terminal Meaning

NO10 normally open contact digital output 10

COM common digital outputs 9 and 10

NO9 normally open contact digital output 9

The maximum length of the connecting cables of the digital outputs is 10 m (32 ft).

The maximum current allowed on the loads is 10 A.

ANALOG OUTPUTS

Analog outputs 4 and 5.

Terminal Meaning

AO4 analog output 4 (configurable via configuration parameter for PWM / 0-10 V signal)

AO5 analog output 5 (configurable via configuration parameter for PWM / 0-10 V signal)

The maximum length of the connecting cables of the PWM analog output is 1 m (3.280 ft); the one of the connecting cables of

the 0-10 V analog outputs is instead of 10 m (32 ft).

For the settings about the analog outputs look at chapter 6 “CONFIGURATION”.

MICRO-SWITCH

Micro-switch to plug in the termination of the second CAN port (120 Ω, 0.5 W); position micro-switch 1 on position ON to plug in the

termination of the second CAN port (plug in the termination of the first and of the last element of the network).

CAN BUS / MP BUS

For the models with second CAN port the connectors have the following meaning.

Terminal Meaning

CAN + signal +

CAN - / MP signal -

GND ground

The maximum number of devices that can make a CAN network (32) depends on the bus load; the bus load depends on the baud rate

of the CANbus communication and on the kind of device in the network.
