(Note 1)
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.
(Note 2)
When using a capacitive 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 momentary current.)
CAUTION
When using an inductive load such as a relay, always connect a diode in parallel to the load.
When using a capacitive load such as a ramp, always connect a protective resistor serially to the
load to suppress rush currents.
