Product Introduction

The JJJC5 AC enhanced contact relay is an important element in the interlocking equipment, and the main equipment to ensure the safe operation of the system. The signal relay can control the switching of the turnout, lock and unlock the way, and control the opening and closing of the signal machine. Relays are widely used in railway signal technology, called signal relays, which are important components in railway signal technology. It plays an important role no matter as the core component of the relay signal system or as the interface component of the electronic or computer signal system. The reliability of the relay action directly affects the reliability and safety of the signal system.

Product Usage

The JJ small C5 AC enhanced contact relay is used as an indicator light power supply supervisory relay in the power supply screen of the small station.

Features

1. The JJJC5 type relay is an AC 24V heavy elasticity type reinforced contact electromagnetic relay.

2. The relay magnetic system is a clap-on AC magnetic system, which is composed of an iron core, a coil and an armature.

3. The use of silver-silver oxidation requires contacts, which has the characteristics of strong anti-adhesion and low contact resistance.

4. The relay contact system consists of two parts: ordinary contacts and enhanced contacts. There are two groups of moving on and off switching ordinary contacts; the two sets of moving on and off switching enhanced contacts, the structure of the ordinary contacts is the same as the stepless relay, and the strengthened contacts Specially designed high-power contacts.

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, +40°C, a relative humidity of less than 80%, and no acid, alkali or other harmful gases around it. It should not be exposed to rain and snow during storage.

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 that 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 set 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.
