This timer allows users to simply press and hold the top button to initiate override or press and hold two buttons to convert the 15-minute timer into other available time intervals. The Decora 30-Minute Countdown Timer Switch has 5 buttons with 5-minute, 10-minute, 15-minute and 30-minute preset time options and a manual off button. It is ideal in automating control of heat lamps, hot tubs, attic and exhaust fans. It provides convenient timed control of lighting and motor loads in homes, offices, schools, libraries and other small commercial applications. Single Pole, 600W LED/CFL, 1800W Incandescent/Halogen, 1200VA Magnetic Low Voltage/Electronic Low Voltage. The Decora 15-Minute Countdown Timer Switch has 5 buttons with 2-minute, 5-minute, 10-minute and 15-minute preset time options and a manual off button. The LTB15-1LZ, Leviton Decora Timer Switch offers advanced features, superior accuracy and contemporary aesthetics. Decora In-Wall 15-Minute Countdown Timer Switch, 15A, HP/9.8A Fan/Motor, Single Pole. White assembled on device, Ivory and Light Almond included. White finish, with ivory and light almond finishes included.ĭecora Preset 15 Minute Countdown Timer - 120VAC, 60Hz, 1800W Incandescent, 600W CFL, 5A LED, 20A Resistive/Inductive, 1HP, single pole 3-way or more locations, four preset buttons for 2-5-10-15 minutes, neutral required. Or, IC2 stopped working, just press the switch S2 to reset or unplug the circuit.Leviton Decora Electronic Timer Switch. It result in appliances are working such as fluorescent light up.Īnd after that, time-out quits and IC2 to stop the flow with the TRIAC.Īlso, we can stop the circuit. It will conduct between MT1 and MT2 leads. Which a TRIAC acts as a switch on and off electrical appliances. Solution:-The solution I got, is to use a timer which will be ON for 15 min and then OFF till it gets next trigger. Also, it should play a buzzer as an indication that heater is disconnected. To stimulate the gate (G) of a TRIAC – T1. After 15min the relay should disconnect heater from ac mains. The output of IC2 a pin 1 has a higher voltage level of about 5V. Then sent into the period to pin 2 of IC2 – LM358. The VR1 is timer setting from 1-15 minutes. So, when a switch S1 (Start), IC1 work out as a pulse signal generator via the output pin 3 of IC1. We set time by R3 and C3 at a specified time period as you want. This 10V input voltage is a power supply to IC1 No-555. They run with a high-voltage level to reduce and keep the voltage to 10VDC. There is a DC power supply R1, C1, D1, and ZD1. When we enter 220V AC main to the circuit. We will divide this circuit into 3 parts. It causes this circuit is smaller and easy to use. It uses a TRIAC instead of electrical control, relay. See in circuit below, the 1-15 minute timer circuit. Switching Voltage 120V AC 125V AC 240V AC 250V AC 277V AC Switching Current 10A 15A 16A 20A 21A Minimum Set Time 2 sec. Often we use a transformer to reduce a low voltage down of 9V and 12V. DECORATOR WHITE TIME CYCLE 15 MIN OPERATION TYPE WITHOUT HOLD SPST SWITCH CONTACT CURRENT 20 AMPERE AT 125 VAC 50/60. Timer control 1-15 minutes using Triac 2N6075 and LM555-LM358 Increase C2 or VR1, R2 for longer delays. Then, the buzzer will emit alert us immediately. The buzzer will be silent until the delay is complete. In briefly, C1 discharged, Pin 2 closed to turns IC-555 on. While the current flows R1 to charges in C1. Using VR1 to adjust the timing of the egg timer.įirst, set S1 to “standby”. Also, I use The famous 555 IC, LM555 or NE555 or equivalent. ![]()
