When using an inductive load such as a relay, always connect a diode (voltage
resistance 100V or more, 100mA or more) in parallel to the load.
When using a capacity load such as a lamp, always connect a protective resistor (R=150
Ω
)
serially to the load to suppress rush currents. (Make sure that the current is less than the above
tolerable current including the instantaneous current.)
<CAUTION
>
CAUTION
When using an inductive load such as relays, always connect a diode in parallel to the
load as a noise countermeasure.
When using a capacitive load such as a lamp, always connect a protective resistor in
series to the load to suppress rush currents.
