NOTES
1. Coil operating power
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 a ware that the
pick-up and drop-out voltages will fluctu-
ate depending on the ambient tempera-
ture and operating conditions.
2. LED indications
The light of the light emitting diode is what
displays operation. If voltage remains af-
ter relay dropout, the LED might illuminate
briefly.
3. Switching lifetime
The switching lifetime is defined under the
standard test condition specified in the
JIS* C 5442-1996 standard (temperature
15 to 35
°
C 59 to 95
°
F, humidity 25 to
75%). Chec k 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 f or A C load-oper ating 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 clos-
ing 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 f ormed. This can cor-
rode metal materials.
Three countermeasures for these are list-
ed 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 at-
mospheric pressure during usage, trans-
port, and storage of the relay:
(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 tem-
perature. Use within the range indicated
in the graph below.
(3) Atmospheric pressure: 86 to 106 kPa
Temperature and humidity range for us-
age, transport, and storage:
2) Condensation
Condensation forms when there is a sud-
den 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 tempera-
tures 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 environ-
ments
The plastic becomes brittle if the relay is
e xposed to a low temperature , low humid-
ity environment for long periods of time.
5. Screwing torque of pressure screw
block should be less than 0.5 to 0.8N·m
to avoid breaking heads and bodies.
6. Take care not to touch the button
during normal usage to prevent unex-
pected switching. Test button should
be used only to check the circuit con-
nection.
7. Operation method for test button
1) Push and release
1
gently to confirm
relay switching.
2) To lock to one side turn 90° counter-
clockwise while pushing loc k and turn 90°
clockwise to release.
8. Rating
9. Diode characteristics
1) Reverse breakdown voltage: 1,000 V
2) Forward current: 1 A
10. 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 im-
plement measures to absorb it.
