2 A for 250 V
a and 30 V c
• Sampling time: 8 ms
• Service life: 100,000 operations at maximum switching power
COM Analog I/O common 0 V
+10 Power supply for reference
potentiometer (2.2 to 10 k
Ω)
• +10 V (+ 8% - 0%)
• 10 mA max
• Protected against short-circuits and overloads
AI2 Analog voltage input Bipolar analog input 0 ± 10 V (maximum safe voltage ± 30 V)
The + or - polarity of the voltage on AI2 affects the direction of the setpoint and
therefore the direction of operation.
