NOTES
1. Coil applied voltage
Please refer to “RATING” about coil input
power supply.
2. LED display
Operation is displayed by the light
emitted from the LED. The LED may
remain brie?y lit if voltage remains after
the relay opens.
3. Switching lifetime
The switching lifetime is de?ned under
the standard test condition speci?ed in
the JIS* C 5442 standard (temperature
15 to 35 ° C 59 to 95 ° F , humidity 25 to
75%). 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
4. Usage, transport and storage
conditions
1) Temperature, humidity and pressure
during usage, storage and transport
(1) Temperature:
–40 to +70 ° C –40 to +158 ° F
(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.

2) High-frequency load-operating
When high-frequency opening and
(3) Atmospheric pressure: 86 to 106 kPa
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 HNO 3 is formed. This
can corrode metal materials.
2) Condensation
Condensation forms when there is a
sudden change in temperature under
high temperature and high humidity
conditions. Condensation will cause
3) Do not use the test button for anything
other than testing, such as when
checking the circuit.
6. Diode characteristics
1) Reverse breakdown voltage: 1,000 V
Three countermeasures for these are
deterioration of the relay insulation.
2) Forward current:

listed here.
(1) Incorporate an arc-extinguishing
circuit.
(2) Lower the operating frequency
(3) Lower the ambient humidity
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.
7. 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.
8. Please connect DC coil types with
LED and built-in diode correctly by
verifying the coil polarity (“+” and “–
”). Connecting with reverse polarity
will cause the LED not to light and
damage the built-in diode due to its
speci?cation.
