When a relay contact is open the relay is not energized. I cover 34 and 5 pin relays and all you need is a 12v source a multimeter and a test light.
3 Ways To Test A Relay Wikihow
How to test a 8 pin relay. Since the coil pin. Try to touch the probes of multimeter on a pair of pins. Automotive test lights are available at auto parts stores and hardware stores. With the relay in the configuration that has the 2 load pins connected place the test voltage on 1 of the load pins of the relay and an automotive test light on the other load pin of the relay. All no contacts should read infinite resistance to the corresponding pole. The simplest way of finding this is to use a multimeter with an ohmmeter setting and then measuring the resistance values by checking its terminals.
In either case. Multimeter used in video. Set the multimeter to. Test the de energized condition of the relay contacts. This includes the com terminal the normally open terminal and if the relay is a double throw relay the normally closed terminal. Here we look at relay switch pin diagram and the different kinds of relay switches.
8 pin and 11 pin pla relay ke connection lagbhag same hote hai bas 11 pin. The main reason for testing a relay is to find whether it is a good or defective one. 8 pin pla relay connection and pin diagram friends is video mai ham 8 pin pla relay ke connection discuss kar rahe hai. Here is a video on how you can test a relay with or without a diagram. Same as previous parts lets start with determining the relay coil pins using a multimeter. Relays switches are used to open and close circuits electromechanically or electronically.
Turn back the relay to see pins located at its bottom part. All nc contacts should read 0 ohms to the corresponding pole. The automotive test light should light. When a relay contact is closed there is a closed contact when the relay is not energized. 8 pins relay src 05vdc sh 1. Use a digital multimeter dmm to test the resistance between each pole of the relay and the corresponding nc and no contacts for that pole.
Test the relay contacts with an ohmmeter besides the coil terminals you then can check to see if the the other terminals are good as well.
