System and load checks

The PDF identifies the control ports but does not provide a full compatible-model list or relay contact-load rating. Do not infer those ratings from the board’s 5 V supply requirement.
HD-K524 frequently asked questions
What does the Huidu HD-K524 control?
The K524 provides six-channel power-switch control for a compatible LED display system. The specification lists a sending-card/player-box connection and a timing function for scheduled switching and delay applications.
Can K524 adjust LED display brightness automatically?
The controller has one photosensitive-probe port. With the appropriate probe and compatible control-system configuration, the document describes automatic brightness adjustment according to ambient light. It does not specify an illuminance range or brightness accuracy.
What voltage powers the K524 board?
The specification recommends a standard 5 V supply and lists 4.2 V minimum and 5.5 V maximum. These values describe the controller supply, not the voltage or current rating of the switched load.
What is the maximum relay contact current?
The linked K524 specification does not state relay contact voltage, current or load-type limits. Obtain the applicable contact ratings and switching arrangement for the supplied board before choosing the controlled equipment.
What should I check if timing settings are not retained?
The document instructs users to check that the control-card battery is secure so timing information can be retained. It also calls for stable power to the control card and relay during operation.
