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.
