About this item

  • Main Chip: NE555, Operating voltage: 12V DC
  • Possess of input power indicator and relay pull-in indicator
  • Adjustable Delay timer switch can be used with other circuits to provide a time delay for other appliances.
  • The delay time is adjustable (0 to 10 seconds), can control AC 220V/10A equipment (Maximum control equipment 2000W).
  • Compatible with Arduino, Raspberry Pi, AVR, PIC, 8051


Description:
Size: 66*21*12mm, Weight: 9g
Main Chip: NE555
Operating voltage: 12V DC

Feature:
1. Turn on the power relay and delay the pull-in. Specifically: after supplying 12v power to the relay, the relay will not 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 relay will immediately suck 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

I installed an amp alongside our family room receiver, but now we have to make sure to turn both components off every time we turn the TV off.These timer relay switches from Haldzemo allow me to set it up so the amp will power off approximately 5 seconds after the receiver is turned off.They were reasonably priced and include nine relays, so I can add efficiencies to other appliances as well.

Useful to be able to sequence actions based on timed relays. Well made and work well.

Apply power to this device and after an adjustable time the relay built in will operate and remain operate until power is removed. Relay contacts are a single circuit either normally open or normally closed.
