Digital output 6 (electromechanical relay).
Terminal
Meaning
CO6
common digital output 6
NO6
normally open contact digital output 6
NC6
normally closed contact digital output 6
The maximum length of the connecting cables of the digital(6)
non
hecto only)
Analog outputs.
Terminal
Meaning
VDC
power supply driving analog output 1 (24 VDC, 50 mA max.)
AO1
analog output 1 (PWM signal)
GND
ground
AO2
analog output 2 (configurable via configuration parameter for 0-20 mA / 4-20 mA / 0-10 V signal)
AO3
analog output 3 (configurable via configuration parameter for 0-20 mA / 4-20 mA / 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 0-20 mA / 4-20 mA / 0-10 V analog outputs is instead of 30 m (98 ft).
For the settings about the analog outputs look at chapter 6 “CONFIGURATION”.
The analog output 1 is usable on condition that the controller is powered in alternate current and the phase powering the controller is the
same powering the user driven by the output.
ANALOG INPUTS/OUTPUTS (in c-pro 3 hecto+ only)
Analog inputs and analog outputs.
Terminal
Meaning
AI4
analog input 4 (NTC probes)
AO1
analog output 1 (PWM signal)
GND
ground
AO2
analog output 2 (configurable via configuration parameter for 0-20 mA / 4-20 mA / 0-10 V signal)
AO3
analog output 3 (configurable via configuration parameter for 0-20 mA / 4-20 mA / 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 0-20 mA / 4-20 mA / 0-10 V analog outputs is instead of 30 m (98 ft).
