Customer Questions & Answers
-
Question:
Can it control home appliances?
Answer: Yes, the module can be used to control home appliances. -
Question:
What type of control signals does it accept?
Answer: The module accepts TTL 5V-12V control signals. -
Question:
Can this module be used as a microcontroller development board?
Answer: Yes, the kits module can be used as a microcontroller development board. -
Question:
Can I supply the board with 12V instead of 5V?
Answer: The boards are built with 5V relays, but they can work at 12V, although they will draw more current and might have a shorter lifespan. -
Question:
Can the high power side supply power for the low power side?
Answer: No, the relay itself needs 5V DC power. You can use the 5V output pins of your control device (e.g., Raspberry Pi or Arduino) to power it. -
Question:
Can I control the relay with a 12V signal?
Answer: No, these relays are designed to trigger with a 3-6V signal. Using a 12V signal is too much voltage for triggering. -
Question:
Can I use a PC PSU and a Raspberry Pi to control the relay?
Answer: Yes, you can use the 3.3V from the Raspberry Pi's GPIO port to turn on the relay and ground the green wire on the PSU. -
Question:
Will this relay engage with 2.5V DC?
Answer: Yes, the relay can engage with a 2.5V DC signal. It works perfectly with 2.1V DC as well.
