Measuring contact resistance

Use the resistance gear of the multimeter to measure the resistance of normally closed contacts and moving points. The resistance value should be 0; The resistance of normally open contacts and moving points is infinite. From this, it can be distinguished which is normally closed contact and which is normally open contact.

When selecting relay, the power supply voltage of general control circuit can be used as the basis for selection. The control circuit shall be able to provide sufficient working current for the relay, otherwise the relay closing is unstable. After consulting the relevant data to determine the service conditions, find out the model and specification number of the required relay. If the old relay needs to be replaced, confirm whether the flange size is appropriate.

Before selecting gas relay, understand the necessary conditions:
â‘  The power supply voltage of the control circuit and the maximum current that can be provided;
â‘¡ Voltage and current in the controlled circuit;
â‘¢ The controlled circuit needs several groups and what form of contacts.
