NOTES
1. Coil 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 briey lit if voltage remains after
the relay opens.
3. Switching lifetime
The switching lifetime is dened under
the standard test condition specied 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
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. 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.
Temperature and humidity range for
usage, transport, and storage
(3) Atmospheric pressure: 86 to 106 kPa
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. Operation method for test button
1) Push and release 1 gently to conrm
relay switching.
2) To lock to one side turn 90
° counter-
clockwise while pushing lock and turn 90
°
clockwise to release.
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
2) Forward current:
1 A
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.
