<Caution>
∗
When using an inductive load such as a relay, always connect a diode (voltage
resistance 100V or more, 100mA or more in reverse direction) in parallel to the
load. Note that the device will be damaged if the diode orientation is incorrect.
∗
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
momentary current.)
When using an inductive load such as a relay, always connect a diode in parallel to the
load as a noise countermeasure.
When using a capacity load such as a lamp, always connect a protective resistor serially
to the load to suppress rush currents.
