Low Voltage: This delayed relay module can operate with a low voltage of 3V or more.<br> Wide Usage: The switch is widely used to control motors, light bulbs, LED belts, DC motor, small pumps, etc.<br> Supply: 3.7V Lithium Batteries, 5V Power Supplies, Switching Power Supply can be used to power this relay card.<br> Optimal isolation: The isolation of the optical coupling of the module improves the anti-interference ability.<br> printed circuit board: The module uses a printed circuit board on an industrial level and saves the set parameters after a power failure.<br> Working current: DC 3V ~ 7V.<br> Voltage range with tab: 3 V ~ 5.5 V.<br> Voltage range without tab: 3.8 V ~ 7 V.<br> Signal source: DC 3V ~ 12V (usually use positive trigger, button, PNP sensor, PLC signals, etc.)<br> Output Capacity: Can control the devices in DC 30V 3A or AC 220V 3A.<br> Quiescent current: 15 mA Working current: 30 mA.<br> Lifespan: 100,000 times.<br> Operating temperature: -40 ~ 85 Celsius.<br> Tips:<br> Mode selection: After power on, long press K1 for 2 seconds, short press K1 to enter selection mode P1~4 selection, K2 enter mode.<br> P-1: The signal triggers the relay to pull in. When the time is up, the relay is disconnected. During the delay period<br> A: Trigger again is invalid B: Trigger again to re-timing C: Trigger the relay again to reset and terminate timing<br> P-2: Signal trigger start timing time T1, when the time is up, the relay pull-in time T2 is disconnected (reset)<br> P-3: Recycling use: turn on T1, turn off T2, endless loop. T1 and T2, the time is adjustable<br> Colour:blue<br> Material:Electronic component<br> Size:64.2x34.8x15mm<br> Package Contents:<br> 1 x Time Delay Module<br> Only the above package content, other products are not included.<br> Note: Light and different displays may cause the color of the item in the picture a little different from the real thing. The measurement allowed error is +/- 1-3cm.<br> Note: Due to the light and screen setting difference, the item's color may be slightly different from the pictures. Please allow slight dimension difference due to different manual measurement. Sold by-Dadangjia
