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.
The analog output 1 and the analog output 2 are not independent each other but they work in the same way.
DIGITAL INPUTS
Free of voltage digital inputs.
Terminal Meaning
COM common digital inputs
DI1 digital input 1
DI2 digital input 2
DI3 digital input 3
DI4 digital input 4
DI5 digital input 5
The maximum length of the connecting cables of the digital inputs is 100 m (328 ft).
ANALOG INPUTS
Analog inputs.
Each analog input is configurable via configuration parameter for PTC / NTC / Pt 1000 probes / 0-20 mA / 4-20 mA / 0-5 V ratiometric /
0-10 V transducers.
Terminal Meaning
AI1 analog input 1
AI2 analog input 2
AI3 analog input 3
GND ground
+5V power supply 0-5 V ratiometric transducers (5 VDC, 40 mA max.)
+24V power supply 0-20 mA / 4-20 mA / 0-10 V transducers (24 VDC, 120 mA max.)
The maximum length of the connecting cables of the analog inputs and the one of the power supply of the transducers is
100 m (328 ft).
The controller incorporates a restorable thermal protection of the power supplies against the short circuit and the overload.
