Technical Specifications:
Supply voltage: 12V DC
Output type: direct 12V output (controlled switched power)
Output current: up to 20A
Trigger input: 12V positive or negative pulse
Dimensions:
PCB: 35 × 18 × 12 mm
Enclosure: 40 × 17 × 21 mm
Prewired leads: 10 cm
Wiring Description:
Red: +12V supply
Black: GND (–12V)
White: +12V output
Blue: GND output
Orange: Trigger input (+12V activation)
Brown: Trigger input (–12V activation)
Operating Principle:
When powered, the module stays in standby until a trigger signal is received. After activation, it switches the 12V output ON and keeps it active for the preset time. After the delay expires, the output turns OFF automatically.
Automotive Application Example (Headlight Control):
Used for delayed shutdown of vehicle lights. Trigger is connected to the light switch (orange wire). Power is supplied from the battery through a proper fuse. Output directly feeds the lighting circuit.
When activated, the module supplies 12V to the lights. When deactivated, the timer keeps lights ON for the set delay, then cuts power automatically.
Important Note:
Maximum load is 20A. For higher loads, use an external power relay.
