Feature:
1. Using dedicated time chip NE555 as the main control, time is accurate and stable.
2. The jumper settings on the board allow you to switch between functions A and B. The default is set to A mode.
3. Adjust the time with an adjustable resistor with a delay range of 0.1-5 seconds.
4. No external start is required, and the power will automatically enter the delay state.
5. Typical design operating voltage is 12V DC.
6. Standby only 3mA current, saving power.
7. The power supply has anti-reverse protection, and the reverse power supply will not work or burn the module.

Specification:
Condition: 100% Brand New
Item Type: Time Delay Relay Module
Voltage: DC 12V (10V-15V can be used)
Power Consumption: Standby 0.04W
Work: 1.0W
Startup Mode: start timing on power-on
Time Range: 0.1-5 seconds
Delay Accuracy: 1%
Load: AC 250V 30A or DC 30V 30A
Output form: A group of normally open + normally closed
Can be set to one of two modes of operation:
A: Power on immediately, after the delay arrives, disconnected (maintained disconnected until the input is powered off);
B: It will not operate after power-on, and will be turned on after the delay arrives (always on until the input is powered off).
A Mode: After the module is connected to the power supply, the red indicator light indicates that the power is on. The relay works immediately and the green indicator light is on. At this time, the normally open and common terminals are switched to the on state (the normally closed terminal is disconnected). - After a period of time, the relay is turned off and the green indicator is off. At this time, the normally open and the common terminal are switched off (the normally closed terminal is turned on). Keep this state until the input is powered off.
B Mode: When the module is connected to the power supply, the red indicator light indicates that the power is on. The relay does not move, the green indicator light does not illuminate, and the normally open and the common terminal remain in the off state before the power is turned on (the normally closed terminal is turned on). After a period of time, the relay is turned on and the green indicator light is on. At this time, the normally open and the common terminal are switched to the on state (the normally closed terminal is disconnected). Keep this state until the input is powered off.
