Connection
H3Y-2
H3Y-4
Connect the DC power supply to
terminals 13 and 14 according
to the polarity marks.
Connect the DC power supply to
terminals 13 and 14 according to
the polarity marks.
Precautions
When selecting a control output, use the H3Y-2 for switching ON
and OFF the power and the H3Y-4 for switching ON and OFF the
minute load.
The operating voltage will increase when using the H3Y in any place
where the ambient temperature is more than 50
°
C. Supply 90% to
110% of the rated voltages (at 12 VDC: 95% to 110%) when operat-
ing at 50
°
C or higher.
Do not leave the H3Y in time-up condition for a long period of time
(for example, more than one month in any place where the ambient
temperature is high), otherwise the internal parts (aluminum elec-
trolytic capacitor) may become damaged. Therefore, the use of the
H3Y with a relay as shown in the following circuit diagram is recom-
mended to extend the service life of the H3Y.

H3Y
Do not connect the H3Y as shown in the following circuit diagram on
the right hand side, otherwise the H3Y’s internal contacts different
from each other in polarity may become short-circuited.
Correct
Incorrect
Use the following safety circuit when building a self-holding or self-
resetting circuit with the H3Y and an auxiliary relay, such as an MY
Relay, in combination.

Do not use the H3Y in places where there is excessive dust, corro-
sive gas, or direct sunlight.
Do not mount more than one H3Y closely together, otherwise the
internal parts may become damaged. Make sure that there is a
space of 5 mm or more between any H3Y Models next to each other
to allow heat radiation.
The internal parts may become damaged if a supply voltage other
than the rated ones is imposed on the H3Y. When more than 100 V is
applied to 12 or 24 VDC, the internal element (varistor) may break.
