10PCS DC 12V NE555 Delay Timer Relay Switch Module, Adjustable 0-10 Seconds Constant Current Regulator Timer Delay

10PCS DC 12V NE555 Delay Timer Relay Switch Module Adjustable 0-10 Seconds Constant Current Regulator Timer Delay Converter for Automotive Control System Electrical Equipment

10PCS DC 12V NE555 Delay Timer Relay Switch Module, Adjustable 0-10 Seconds Constant Current Regulator Timer Delay

Specification: Module chip: NE555 chip Delay modue: delay connect module Input voltage: DC12V Control voltage: AC 0~250V / max 10A, DC 0~30V / max 10A the operating voltage: 12 volts DC; (otherwise 5V optional) Max load: 2200W Applications: Vehicle equipment-delay to prevent car ignition, prevention of high sudden current to burn components and devices. Module performance and features: 1.Turn on the power relay and delay the pull-in. Specifically: after supplying 12v power to the relay, the relay will immediately suck and relay output status: Normally open and public disconnect, normally closed and public conduction; wait until the delay is 1-10s (can be adjusted), the release of the relay and at this time, the state of the relay output is: Normally open and public conduction, normally closed and public disconnect; this state will be maintained as long as the module is continuously powered. 2. The delay time is adjustable, (0 ~ 10 seconds) 3. Increase the potentiometer can increase the delay time 4. Increase the capacitance C1 can increase the delay time 5. Possess of input power indicator 6. Possess of relay pull-in indicator 7. can control the AC 220V/10A equipment. (Maximum control device 2000W) 8. Possess of relay freewheeling protection 9. Delay time formula: T=1.1RC. For example: Capacitance 100uf resistance 100K T = 1.1 * 100000 * 0.0001 = 11 seconds Package Included: 10 X NE555 DC 12V delay timer module

Key Features
