• 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:
The rated voltage is 5–24 V DC or 12–24 V DC. Therefore, the voltage between
the terminals is within the specified range.
Voltage between terminals (three G3PA units)
= Voltage when open − Internal resistance × Total drive current
= 19 V DC ±15 % − 18 Ω ±0.5 % × 21 mA
≈ 16 to 21 V
