The maximum length of the connecting cables of the digital inputs is 100 m (328 ft).

The digital inputs can be used on condition that they are powered at 24 VAC / DC.

ANALOG INPUTS

Analog inputs 1, 2, 3, 4 and 5.

Each analog input is configurable via configuration parameter for PTC / NTC / NTC 2 / NTC 3 / Pt 1000 probes / 0-20 mA / 4-20 mA /

0-5 V ratiometric / 0-10 V transducers, but the analog input 2 of the models with second CAN port which is configurable via configuration

parameter for PTC / NTC / NTC 2 / NTC 3 / Pt 1000 probes.

Terminal Meaning

GND ground

AI1 analog input 1

AI2 analog input 2

AI3 analog input 3

AI4 analog input 4

AI5 analog input 5

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.

POWER SUPPLY

Power supply.

Terminal Meaning

V≅

power supply controller (24 VAC / 20... 40 VDC)

V≅

power supply controller (24 VAC / 20... 40 VDC)

The maximum length of the connecting cables of the power supply of the controller is 30 m (98 ft).

Protect the power supply with a fuse rated 2.5A-T 250 V.

If the controller is powered in direct current, one will not have to respect the polarity of the power supply voltage.
