Product Usage

Programmable time relays include JSBXC-780, JSBXC-820, JSBXC-820, JSBXC1-850, and JSBXC1-870 series relays. Each type of relay has four types of warm-up time to choose from, including JSBXC-820 series The heating time can also be changed according to the special requirements of users. The relay is used as a delay control in the circuit.

Product electrical life

When the contact of the relay is connected to a resistive load of DC 24V, 1A, its electrical life should reach 2×106 times.

Packaging, transportation, storage

(1) Packaging

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.

(2) Precautions for transportation

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

(3) 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, a relative humidity of less than 80%, and no acid, alkali or other harmful gases around. 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.

Product barcode

The relay company bar code is pasted on the armature, and the Ministry of Railways bar code is pasted on the external device. When the product has quality problems or the user has doubts about the product quality, the user should consult the digital code of the bar code, and timely feedback to the company so that the manufacturer can obtain the product information in the first time and realize product quality tracking and after-sales service.

After-sales service

From the date of delivery, the warranty period of infinite relays, rectifier relays (the warranty period of electronic components is one year), polarized relays and biased pole relays is 1 year, and the warranty period of infinitely enhanced contact relays and polarized enhanced contact relays Provide free maintenance services for the company during the one-year warranty period; beyond the warranty period, the company will provide life-long technical support based on the actual situation and maintenance items. The company provides life-long technical support to create conditions for users to master the use and maintenance methods of the relay.

a) The relays that have been unsealed due to poor quality or damage due to transportation, storage, improper use, etc., are not covered by the company's warranty;

b) If the user violates the technical requirements of this manual or fails to perform normal maintenance according to the maintenance manual during installation and use, the company does not assume any responsibility for the damage;

c) During the company's warranty period, if the products and parts of Shanghai Shenxin Railway Signal Equipment Co., Ltd. are unpacked without the company's authorization, the company will not bear any responsibilities arising therefrom;

d) Non-Shanghai Shenxin Railway Signal Equipment Co., Ltd. components are assembled into the company's products without the company's consent and cause product quality problems, and the company does not assume any responsibility for any damage arising therefrom;

e) The company does not assume any responsibility for damage caused by natural disasters, such as earthquakes, floods, lightning strikes, landslides, etc. irresistible causes;

f) The company does not assume any responsibility for damage caused by damage, theft or fire extinguishment, or damage caused by other reasons not caused by the company.
