1) Working voltage: wide voltage 5V--30V, MicroUSB is 5v DC input, and welding tow terminal DC 6.3v~30v is okay
2) With trigger port, can use lower voltage(GND signal) to trigger or click board button to trigger.
3) Relay LED indicator, wide range working voltage, more stable
4) Adjust time range, 0~24 seconds
5) Relay Capacity: 250vAC 10A, 36vDC 10A
6) Board size: 5.4*1.9*1.8cm
7) Weight: 16g.
Work mode:
Connect module to power supply,
the module output state is: normally open (NO) and common side (COM) is disconncect, normally closed (NC) and common (COM) is connect.
In the external contact (TRIG) to start a low pulse signal, or touch the trigger button instantly, the relay active and the indicator light,
the relay output state is normally open (NO) and the common end (COM) is connect, normally closed (NC) and the common end (COM) disconnected,
after 0-24 seconds (this time can be adjusted according to your needs) after the relay is switched off, the relay back to the state before the trigger.
1) alarm delay, building sound and light control switches etc..
2) car equipment delay turn on, avoiding the current is too large to prevent the car ignition burning vehicle equipment.
