Product Usage

The JWXC-H600 type stepless slow release relay is used as a general relay in the signal circuit.

Applicable environment

The applicable environment of the relay is:

a) Ambient temperature: -40℃~+60℃;

b) Relative humidity: not more than 90% (temperature +25°C);

c) Air pressure: not less than 70kPa (equivalent to an altitude below 3000m);

d) Vibration: the vibration frequency is not more than 15Hz, and the amplitude is not more than 0.45mm;

e) Working position: horizontal;

f) There should be no harmful gas causing explosion hazard around, and good dust-proof measures should be taken.

Mechanical properties

Number of contact groups: 8QH;

Identification pin number: 12, 51;

Contact gap: not less than 1.3mm;

Pallet gap: not less than 0.35mm;

Contact pressure: the dynamic contact point is not less than 250mN; the dynamic disconnection point is not less than 150mN;

Contact uniformity error: not more than 0.20mm.

Structural characteristics

In order to increase the action time, the stepless slow release and slow action relays adopt a full frame of copper damping wire. The copper bobbin is equivalent to a short-circuit ring. When the coil is de-energized, the eddy current is generated in it to organize the disappearance of the magnetic flux in the iron core, thus increasing the delay time of the relay. The magnetic system of JWXC-H310 type stepless slow-acting relay also adds a copper short-circuit ring to make slow suction and slow release time longer.

Insulation withstand voltage

Under the standard atmospheric conditions of the test, the insulation resistance of the relay should not be less than 100MQ.

Under the condition that the air pressure is not less than 86kPa (equivalent to the altitude below 1000m), the insulation withstand voltage of the relay should be able to withstand AC sine wave 50Hz,

1000V rms voltage, there should be no breakdown flashover after 1min, and the voltage during repeated test should be 75% of the original test voltage.

Installation Precautions

1. When installing the relay, make sure that the insulation interval between the sockets is intact, the socket hanging spring is intact, and the socket identification pin is in the correct position and should not be missing.

2. Pay attention to the relative position between the relay and the socket when plugging in the relay to avoid damage to the relay or socket during plugging.

3. When repairing and replacing the relay, first remove the fixed relay spring, and then pull out the relay. Do not use excessive force or shake left and right when pulling it out, as it may damage the relay or socket.

Product electrical life

The relay contacts are connected to DC24V1A resistive load; its electrical life is 2×106 times.

maintenance

Daily maintenance and maintenance:

a) Keep the relay and socket clean;

b) Observe whether the relay operation status is normal;

c) The relay should be replaced in time for abnormal operating conditions and serious contact burnout.

Regular maintenance:

In the electrical life and life management cycle of the relay, the maintenance cycle of the stepless relay and the rectifier relay should be five years.

The overhaul period of stepless reinforced contact relays, poled relays and biased pole relays should be three years.

The overhaul period of stepped reinforced contact relays should be one year.

Appearance inspection and performance inspection should be carried out after the overhaul.

Packaging, transportation, storage

package:

The outer packaging of the relay adopts a carton structure, and the carton is equipped with a foam box to ensure that the relay will not damage the instruction manual of the relay in each packaging box during the normal transportation process.

Matters needing attention in transportation:

During storage and transportation, the relay should not be subjected to strong vibrations, collisions, or rain or snow.

Storage conditions, storage period and precautions:

The relay should be stored in a well-ventilated warehouse with a temperature of -25°C, 10-40°C, and a relative humidity of not more than 80%, and no acid, alkali or other harmful gases around it. It should not be exposed to rain and snow during storage.

The storage period is one year, and the storage period should be inspected or repaired before use.
