•  Input current:   Since the input current is 7 mA or less, up to three units 
(7mA × 3 = 21 mA < 24 mA [maximum allowable current]) 
can be connected in parallel.
•  Operating voltage range (input):   The rating voltage is 5 to 24 V DC or 12 to 
24 V DC.  Therefore, the voltage between 
the terminals is within the range.
Voltage between terminals (three G3PA units)
= Open voltage - internal resistance × total drive current
= 19 V DC ±15 % - 82 Ω ±0.5 %  × 21 mA
 14 to 20 V
