Faults and troubleshooting methods

the relay does not work or the relay with a pole cannot be reversed in the forward direction

the relay does not work or the relay with a pole cannot be reversed in the forward direction. the analysis and troubleshooting methods are as follows:

(1) Make sure that the relay and socket should be reliably plugged in;

(2) Check that the input voltage or current of the relay coil should be the rated value or the system circuit adjustment value.

Method: Use a multimeter to check the voltage relay coil input terminal voltage on the socket should meet the output voltage of the power supply screen; use a multimeter to check the voltage drop of the current relay coil input terminal on the socket should meet the voltage drop requirements of the system circuit for reliable operation of the relay; otherwise, system error;

(3) If the above two items are normal, it can be determined that the relay is faulty and the relay should be replaced;

(4) the relay coil is short-circuited or disconnected, the relay cannot work reliably or has a pole relay;

(5) the diode of the rectifier relay is impacted or short-circuited, and the rectifier relay cannot work reliably;

(6) Check that the relay should not be mechanically blocked. If a foreign object in the relay blocks the armature, the relay cannot work reliably or reverse polarity.

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 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 contacts are connected to DC24V1A resistive load; its electrical life is 1106 times.

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, please refer to the digital code of the bar code and feedback the company in time, so that the manufacturer can obtain the product information in the first time, and achieve product quality tracking and after-sales service.
