  1. Working voltage: Wide-voltage 5-30V, two power supply terminals or the interface Micro USB KF301
  2. Operating mode: power supply, the output of the module status: normally open (NO) and the common terminal (COM) open, normally closed (NC) and the common terminal (COM) is turned on. Originating outside the contact (TRIG) to a low pulse signal, or touch button to trigger instant, and relay, work lights, and the status of the relay output: normally open (NO) and the common terminal (COM) is turned on, normally closed (NC) and the common terminal (COM) is disconnected after 0-24 seconds (this time can be adjusted according to your needs) relay is switched off after the bell, then relay back to the state before the trigger.
  3. The time can be adjusted by potentiometer, default 0-24 seconds. If you need more time, may be replaced by the larger capacitor (C2) or potentiometer. Delay time formula: T = 1.1RC. For example: Capacitor 22uf resistance 1M T = 1.1 * 0.000022 * 1000000 = 24.2 seconds.
  4. With relay indicator.
  5. Control: 10A 250VAC (AC), 10A 30VDC (DC) or less load.
  6. Has a freewheeling protection relay.
  7. Signal terminal block has a pull-up and design of the filter circuit, and anti-jamming capability, suitable for industrial control. Many manufacturers have added optocoupler isolation, but with the trigger signal to the module and not isolation, would not achieve the interference effect. After the test was found to improve the stability of the trigger end to interference, whether in this module under an electromagnetic interference environment or through the instant power module, the relay will not malfunction.
  8. Size: 5.4 * 1.9 * 1.8cm (L * W * H)
  9. Weight: 16g


  • The anti-theft alarm delay, building sound, and light control lamp switch.
  • Delay-vehicle device is turned on, when the car ignition to prevent excessive current burn-vehicle equipment.
