HD-Y1 auxiliary control card for LED screens
The Huidu HD-Y1 multifunction card adds relay switching, audio output and environmental monitoring to a compatible LED control system. The V1.0 specification identifies communication with the T901 synchronous sending card over Gigabit Ethernet.
Power scheduling and cabinet monitoring
Eight relay-control channels support timed switching for connected equipment. An onboard module monitors temperature and humidity inside the cabinet, while external temperature, temperature/humidity and brightness sensors can connect through the designated interfaces.
Configure the card in HDSet under Function → Multi-Function Card. It can be placed before, between or after receiving cards as shown in the specification. Confirm the actual controller setup and load requirements before wiring the relay contacts.

Frequently asked questions
What does the HD-Y1 add to an LED display system?
It adds eight-channel relay control, timed switching, an audio output and cabinet temperature/humidity monitoring. It is an auxiliary multifunction card rather than the sending or receiving card that generates the LED picture.
Where can the Y1 be connected in the signal chain?
The specification shows it between the sending card and first receiving card, between receiving cards, or after the last receiving card. The two Gigabit ports are interchangeable.
Which sensors can be connected?
The PDF identifies an 18B20 temperature interface at P5, an AM2301 temperature/humidity interface at P6 and a brightness-sensor interface. It also includes an onboard temperature/humidity module.
How do I configure timed power switching?
Open HDSet and choose Function → Multi-Function Card to access the related settings. Match the relay wiring and connected load to the documented contact ratings before enabling the schedule.
Is the 250 VAC rating the power supply for the card?
No. The card supply is DC 4.2–5.5 V, with 5 V recommended. The 250 VAC and 3 A figures are power-management control-contact ratings, not the board input voltage.
