Huidu HD-Y1 LED Display Multifunction Card
The HD-Y1 provides power-switching control, audio output and environmental monitoring for an LED display system. It communicates with the T901 synchronous sending card through Gigabit Ethernet and can be placed before, between or after receiving cards in the cascade.
Relay Control and Cabinet Monitoring
Eight relay-switch channels support power control, including timed switching that can serve the timer function. An onboard temperature/humidity module monitors conditions inside the cabinet. External temperature or temperature/humidity modules can also connect through the designated interfaces.
