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.

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

PROG

Programming and debugging port.
