5V12V Time Delay Turn On/Off Relay Module

several new features compared to otheronline similar products.

1). The power supply has anti-reflexive, preventing the anti-bad chip.

2).Power supply uses integral filtering circuit, super anti-anti-interference.

3). Delay time 0-60 seconds.

4). This module standby without power consumption.

Parameters:

1.size: 6.6 * 1.6 * 1.9cm (L/W/H)

2.the main chip: NE555

 3.work voltage: DC 5V or DC 12V

 4. Time adjustable: 0-60s

 5. Increase the potentiometer to increase delay time

 6. Control DC: 30VDC/ 10A below load

 Control AC: 250VAC / 10A below load

 7. Have relay continuation

 8.Module working principle:

< The working principle of Delay Turn On >

Turn on the power relay delay connect.

Specifically: After supplying 5V/12V power supply to the relay, the relay does not immediately halt, the status of the relay output is: normally open and publicly disconnected, normally closed and commonly turned on; After the delay 0-60s (adjustable), the relay connect, at this time, the state of the relay output is: normally open and commonly turned on, often closed and common; as long as the module is constantly electricity, this state will remain.

< The working principle of Delay Turn Off >

The power relay is turned on immediately and then delayed by 0-60s to disconnect.

Specifically: After power supply 5V / 12V power supply, the relay is attached, the state of the relay output is: normally open and commonly turned on, normally closed and publicly disconnected; After the delay 0-60s (adjustable), the relay Disconnect, at this time, the status of the relay output is: normally open and common open, normally closed and commonly turned; as long as the module is constantly electricity, this state will remain.
