Frequently Asked Questions (FAQs)

1. What is the function of relay module?

A relay module is used to control high voltage and current loads such as solenoid valves, motors, AC loads, and lamps. It is designed to interface with various microcontrollers like PIC and Arduino, making it easier to manage these loads.

2. What happens if ECM relay is bad?

If the ECM power relay fails, it can cut off power to the entire vehicle. This can result in the dash lights and warning chimes not working when the key is inserted, and the vehicle may not start or turn over.

3. Do you need a relay module?

A relay module is essential for home automation projects and controlling motors or lighting circuits using low voltage microcontrollers like Arduino. It provides a reliable way to switch high voltage loads using a low voltage signal.

4. What are the different types of relay modules?

There are different types of relay modules available, including 1-channel, 2-channel, 4-channel, and 8-channel relay modules. Some less common options are the 6-channel and 16-channel relay modules.

5. How do you test a relay module?

To test a relay module, set your multimeter to the ohms setting and measure the resistance between the switch pins, usually labeled 87 and 30 on a four-pin relay. There should be no resistance between these pins. If there is, it indicates that the relay is faulty.

6. How do you trigger a relay module?

The method of triggering a relay module may depend on the presence of jumpers on the module. One of the jumpers may control whether the relay is triggered using a high voltage or low voltage. The position of this jumper determines how the relay is triggered in your project's code.
