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 1
10%) 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 dif
ferent
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.
