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

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.

+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.
