30A DC 12V Delay Synchronization Relay Module with Ne555 Chip for Precise Time Control.

1. Using the dedicated NE555 timer chip as the primary controller, the time is accurate and stable. 2. Jumper settings on the board allow you to switch between functions A and B. The default is mode A. 3. Adjust the time with an adjustable resistor, with a delay range of 0.1 to 5 seconds. 4. No external power is required; the power supply will automatically enter the delay mode. 5. The typical operating voltage is 12V DC. 6. Standby current is only 3mA, saving energy. 7. The power supply has reverse polarity protection, and reverse polarity will not operate or will not damage the module.

Specifications: Condition: Brand New Item Type: Time Delay Relay Module Voltage: DC 12V (10V-15V can be used) Power Consumption: 0.04W Standby Working: 1.0W Start Mode: Timer starts on power-up Time Range: 0.1 to 5 seconds Delay Accuracy: 1%: AC 250V 30A or DC 30V 30A Output Shape: One group of normally closed + normally closed Can be set to one of two operating modes: A: Power on immediately, after the delay has elapsed, disconnected (maintained disconnected until the input is powered off); B: It does not operate after power-up and turns on after the delay (remains on until the input is turned off). Mode A: Once the module is connected to the power supply, the red LED indicates that the power is on. The relay operates immediately and the green LED is on. At this point, the normally open and common terminals are switched to the conducting state (the normally closed terminal is disconnected). - After a certain time, the relay turns off and the green LED turns off. At this point, the terminal
