NOTES
1. Coil operating power
1) DC coil
To ensure proper operation, the voltage
applied to both terminals of the coil
should be ±5% (at 20°C 68°F) the rated
operating voltage of the coil. Also, be
aware that the pick-up and dropout
voltages will fluctuate depending on the
ambient temperature and operating
conditions.
2) AC Coil
To enable stable operation of the relay,
apply the nominal voltage. Ensure that
the fluctuation range of the power source
voltage remains, in principle, within +10%
to –15% of the value of the nominal
current. Moreover, the ideal waveform for
the voltage applied to the coil is a sine
curve. If commercially provided power
surce is used, the waveform should be
checked. If a stabilized AC power source
is used, the conditioning equipment may
distort the waveform, and abnormal
heating may result. With AC coils, hum
can be normally stopped by the use of a
shading coil. If the waveform is distorted,
however, the shading coil may be
ineffective.
2. LED indications
The light of the light emitting diode is
what displays operation. If voltage
remains after relay might illuminate
briefly.
3. Switching lifetime
The switching lifetime is defined under
the standard test condition specified in
the JIS C 5442(*2) standard (temperature
15 to 35°C 59 to 95°F, humidity 25 to
75% R.H.). Check this with the real
device as it is affected by coil driving
circuit, load type, activation frequency,
activation phase, ambient conditions and
other factors. Also, be especially careful
of loads such as those listed below.
1) When used for AC load-operating and
the operating phase is synchronous.
Rocking and fusing can easily occur due
to contact shifting.
2) High-frequency load operating
When high-frequency opening and
closing of the relay is performed with a
load that causes arcs at the contacts,
nitrogen and oxygen in the air is fused by
the arc energy and HNO3 is formed. This
can corrode metal materials.
Three countermeasures for these are
listed here.
(1) Incorporate an arc-extinguishing
circuit.
(2) Lower the operating frequency
(3) Lower the ambient humidity
4. Conditions for operation, transport and
storage
1) Ambient temperature, humidity, and
atmospheric pressure during usage,
transport, and storage of the relay:
(1) Temperature:
–50 to +70°C (without LED)
–50 to +60°C (with LED)
(2) Humidity: 5 to 85% RH (Avoid
freezing and condensation.)
The humidity range varies with the
temperature. Use within the range
indicated in the graph below.

Temperature, °C °F
(3) Atmospheric pressure: 86 to 106kPa
2) Condensation
Condensation forms when there is a
sudden change in temperature under
high temperature and high humidity
conditions. Condensation will cause
deterioration of the relay insulation.
3) Freezing
Condensation or other moisture may
freeze on the relay when the
temperatures is lower than 0°C 32°F. This
causes problems such as sticking of
movable parts or operational time lags.
4) Low temperature, low humidity
environments
The plastic becomes brittle if the relay is
exposed to a low temperature, low
humidity environment for long periods of
time.
5. Diode characteristics
1) Reverse breakdown voltage: 1,000 V
2) Forward current: 1 A
6. Diode and CR built-in type
Since the diode and CR inside the relay
coil are designed to absorb the counter
emf, the element may be damaged if a
large surge, etc., is applied to the diode
and CR.
If there is the possibility of a large surge
voltage from the outside, please
implement measures to absorb it
