• Input current: Since the input current is 7 mA or less, up to three
units (7 mA × 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
