DI7 digital input 7
COM common digital inputs
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.
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
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
