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