12V trigger delay normally open relay modules, repeatedly triggering effective.

Selectable high and low trigger? delay time is adjustable from 0 to 25 seconds, the drive signal is completely isolated,
put an end to all interference ultra-stable.

Time can be adjusted by potentiometer, default 0-25 seconds, if you need more time replaceable larger capacitance / potentiometer.

Power supply module with anti-reverse diode.

Module design of signal terminals optocoupler isolation. Anti-interference ability,
able to adapt to the application of high-low two control signals, suitable for industrial control,
The module can be triggered repeatedly.

Application: it can be used in robotics, automotive lamp delay, intelligent product development,
automation equipment, PLC development, intelligent home, burglar alarm delay, and so the development of electronic.

This module is a switch is turned on instantly trigger delay module, as follows:

1. The power supply to the module (12V), the output of the module state: Normally open public disconnected,
normally closed and public turned on.

2. After a trigger signal (instantaneous) trigger, the switch is closed delay (0-25 seconds),
wait for the end of the delay switch is turned off, the trigger signal (Always trigger),
the trigger switch is closed after the start delay, latency end.
At the end of the delay trigger signal still did not stop the end of the delay,
the relay stays energized to stop waiting for the starting signal, the relay is disconnected immediately.
(Delay in the process of repeatedly triggering all are invalid).

This module supply trigger signal may be provided by a separate power supply system
and the module may not be a power system. The trigger level with a high-level pulse or pulses may be low. Versatility.
