RS PRO Automotive Relay Tester

Introducing the RS PRO Automotive Relay Tester, also known as the Relay Buddy. It’s a high-quality device that can quickly give an indication of the general health and functioning of the most common relays often found within the automotive industry. It can be used to perform the following tests: coil resistance, surge suppression device (resistor or diode), open/closed contact integrity, contact cyclic testing for intermittent failure detection, loaded contact continuity, relay contacts stuck open or closed and time to contact closure and opening. It’s an essential piece of test and measurement equipment for those working in industries and applications where there is a high reliance on relays functioning at their optimum performance rate.

Relay testers are devices that are used to check the power of relays that are found within a wide range of applications. They are easy to use devices that can quickly test and identify an unknown relay terminal configuration, while self-configuring it’s own internal circuitry to adapt and perform all the required tests, automatically. It can be used in a range of industries like:

The device will check the control side of the relay by applying a signal to the relay coil, while doing this, it will check for the proper functioning of the relay contacts. By using this relay tester, it operates the relay several times during each test session to get consistency in every test cycle. It will fail the relay and light up the LED light to let the user know that the cycle was unsuccessful during the test session.
