product structure

The electromagnetic system of the rectifier relay is the same as that of the infinite relay. Only the magnetic circuit structure parameters are different. It is mainly to install a half-wave or full-wave rectifier circuit composed of diodes above the contact group.

Insulation withstand voltage

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

Under the condition that the air pressure is not lower than 86kPa (equivalent to the altitude below 1000m), the insulation withstand voltage of the relay should be able to withstand AC sine wave 50Hz, 2000V rms voltage, there should be no breakdown flashover after 1min, the voltage when repeating the test Should be 75% of the original test voltage value.

Product electrical life

The relay contact is connected to DC24V1.5A

Resistive load; its electrical life is 1×106 times.

Features

1. The JZJXC-100 relay is an AC 24V heavy-elasticity reinforced contact rectifying electromagnetic relay, which uses the principle of "constant gravity" to force the moving and closing contacts to open when the coil is de-energized.

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

3. The magnetic circuit adopts electromagnetic pure iron material with small residual magnetism, and a stop piece is installed at the closed position of the armature and the iron core to ensure the minimum air gap of the magnetic circuit, prevent the magnetization of the ferromagnetic parts of the magnetic circuit, and ensure the reliable fall of the relay.

4. The magnetic circuit system of the relay is basically the same as the JWJXC-7200 stepless enhanced contact relay.

5. The contact system is composed of two parts: ordinary contacts and reinforced contacts. There are two groups of moving and breaking ordinary contacts; four groups of moving and closing reinforced contacts without arc extinguishing magnets. The structure of ordinary contacts is the same as that of non-polar relays. The reinforced contacts are specially designed. Of high-power contacts.

6. The relay has a rectifier unit attached to it because there is no place to install the rectifier unit on the contact group. The rectifier unit is a full-wave rectifier composed of four 1N4007 silicon rectifier diodes.

Dimensions

Relay: 165mm×49mm×163mm (length×width×height)

Socket: 157mm×48mm×22mm (length×width×height)

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 broadcasting.

(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.
