[Accessories]

 

Notes) 1. Packing quantity: 10pcs. (Inner carton), 100pcs. (Outer carton)

2. Use the retainer that is shipped with the terminal socket.

3. Products conform to UL, CSA and TÜV, as standard.

4. In order to prevent breakage and disfiguring, the screw tightening torque for the terminal socket should be within the range of 0.5 to 0.8 N•m.

5. When attaching directly to a chassis, please use an M3.5 

 

×

 

 0.6 metric coarse screw thread, a spring washer, and a hexagonal nut.

6. For S1DX timer, use the retainer (Part No. ADX18012).

NOTES

 

1. Coil operating power

 

To ensure proper operation, the voltage 

applied to both terminals of the coil should 

be 

 

±

 

5% (at 20

 

°

 

68

 

°

 

F

) the rated operating 

voltage of the coil. Also, be aware 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

 

°

 

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 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 formed. 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

 

°

 

– 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

 

°

 

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 

exposed 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 lock 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.
