Interface introduction
Power connector blue screw terminal The main power input interface supplies power to the control board and the fan
Fan interface white VH396-4P socket fan output interface refer to the picture for line sequence
Temperature probe interface Connect NTC probe parameter 10K B=3950
Alarm signal port WORK Outputs a high level during normal operation and outputs a low level when the fan is abnormal
Relay interface RELAY An expansion interface that drives a 9V or 12V relay that can be used to control the fan power line When the fan control is stopped the relay is disconnected
