Timer Relay 12VDC 30A 1.0W, Delay Off Cycle Module 0.1 5 Seconds, Automatically Switch

【NE555 CHIP】The 12V timer relay uses dedicated time chip NE555 as the main control, time is accurate and stable. Adjust the time with an adjustable resistor with a delay range of 0.1-5 seconds, and the delay accuracy is 1%. 【A & B MODE SWITCH】The 12V timer PCB settings on the board allows you to switch between functions A and B. The default is set to mode A. 【AUTOMATICALLY TIMER DELAY】There is no external start is required, and the power will automatically enter the delay state. 【ANTI-REVERSE & NO/NC】The power supply has anti-reverse protection, and the reverse power supply will not work or burn the module. The output type is A group of normally open and normally closed. 【DC12V TIMER RELAY】Typical design operating voltage of the timer relay is 12V DC. The relay module standby only 3mA current, which is saving power. Load Capacity: AC 250V 30A or DC 30V 30A
