Frequently Asked Questions
Q: What is the maximum continuous load current for this 433MHz relay switch?
A: While the relay is rated at 30A peak, the recommended continuous rated load current is 15A or less. Using the relay within the 15A rated limit ensures reliable long-term performance and safe operation of connected appliances like water pumps and motors.
Q: Can I use my existing 433MHz remote with this relay receiver?
A: Yes! The receiver uses learning-code technology, which means it can pair with most standard 433MHz fixed-code remotes. Simply follow the code-learning procedure for your preferred mode (Momentary, Toggle, Latched, or Delay) and the receiver will recognize your remote's signal.
Q: What operating modes does this wireless relay switch support?
A: This relay switch supports four operating modes: Momentary (output active only while button is held), Self-Locking/Toggle (press once to turn on, again to turn off), Interlocking/Latched (dedicated ON and OFF buttons), and Delay mode (automatically disconnects after 5, 10, or 15 seconds). Clear stored codes before switching between modes.
Q: What voltage ranges are compatible with this relay switch receiver?
A: The receiver is compatible with both AC 75–220V and DC 9–72V, making it suitable for a wide variety of electrical systems and appliances worldwide, including water pumps, LED lighting, motors, and fans.
