5V-30V Micro USB Power Adjustable Delay Relay Timer Control Module

1. Working voltage:wide voltage 5 ~ 30V, two power
supply interface
2. Operating mode: the initial state, module outputs:
normally open (NO) and the common terminal (COM)
is disconnected, normally closed (NC) and the common terminal (COM) connected.
Providing a low pulse signal, or touch trigger key,
relay and indicator lights, the output of the state: normally open (NO) and Common (COM) connected, normally closed (NC) and the common terminal
(COM) is disconnected.
After 0-24 seconds (this time can be adjusted
according to your needs) relay off,back to the state before the trigger.
3.The length of timing adjustment by potentiometer,
default 0-24 seconds.
If you need more time, you can replace the larger capacitor (C2) or potentiometer.
Delay time T = 1.1RC.
4. With a relay indicator.
5. The module can control: 10A / 250VAC,
10A / 30VDC load.
6. The relay has a freewheeling protection.
7. Dimensions: 5.4 * 1.9 * 1.8cm (L * W * H)
