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.
