Description
5V 12V 24V Headphone Audio Triggered Relay Audio Signal Relay Signal Trigger Detection Voltage Relay Switch Module
Product Description
Detect the audio signal, start the relay; the audio disappears beyond the set delay time, the relay is disconnected; the delay range: 0.1 second to 99.9 seconds adjustable

Function description
P--1: Charge monitoring: when the measurement is lower than the voltage V1, the relay is closed, and the voltage is higher than V2, the relay is disconnected; P--2: Discharge monitoring: when the measurement is higher than the voltage V2, the relay is closed, and the voltage is lower than V1, the relay is disconnected; P--3: Pull-in outside the interval: When the measured voltage is between V1 and V2, the relay is disconnected, and the relay is closed in other cases; P--4: In-zone pull-in: when the measured voltage is between V1 and V2, the relay pulls in, otherwise the relay is disconnected; P--5: Fixed-point monitoring: when the measurement is higher than the voltage V1, the relay is closed, and the voltage is lower than V1, the relay is disconnected; P--6: Fixed-point self-locking monitoring: when the measured voltage is higher than V1, the relay is closed; it always stays closed; until the power is manually cut off P--7: Fixed-point pulse monitoring: when the measured voltage is equal to V1 each time (up and down can float 0.02V), the relay outputs a jog signal
Installation Instructions
Power-on shows that the measured voltage enters the standby state; Press K1 for the first time (it takes more than 1 second to be effective to prevent false triggering) The screen flashes: P --1: K2 plus mode, K3 minus mode Press K1 for the second time, the screen flashes: 12.50 means: V1=12.5V: K2 and K3 adjust V1 Press K1 for the third time, the screen flashes: 13.50 means: V2=13.5V: K2 and K3 adjust V2 Press K1 for the fourth time, the display shows the measured voltage, which means it enters the standby state; Press K4 in standby mode to permanently turn off/on the display and switch to low power consumption mode
