JWXC-H310 Stepless Slow Action Relay
  • Product Details

Product Features

JWXC-H310 type stepless slow-acting relay is used in 97 type 25Hz phase sensitive track circuit, as the repeater relay of JRJC1-70/240 type AC binary relay, and enhances the anti-interference ability of 25Hz phase sensitive track circuit.


Product Usage

JWXC-H310 type stepless slow-acting relay is used in 97 type 25Hz phase sensitive track circuit, as the repeater relay of JRJC1-70/240 type AC binary relay, and enhances the anti-interference ability of 25Hz phase sensitive track circuit.


Features

1. The relay is a heavy elastic DC 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 relay has a long slow suction and slow release time.

5. The contact system is composed of ordinary contacts, with eight groups of common contacts for switching on and off.

6. The rated voltage of the relay is DC 24V.

maintenance

Daily maintenance and maintenance items are as follows:

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 infinite relay and rectifier relay should be five years; the maintenance cycle of the stepless enhanced contact relay, the poled relay and the biased pole relay should be three years; the maintenance cycle of the stepped enhanced contact relay The period should be one year. Appearance inspection and performance inspection should be carried out after the overhaul.
