Timer Relay Module, 4 operating modes. 0.1 - 120 Seconds.

A PROFESSIONAL, versatile and simple relay timer module that is suitable for use in Intruder alarm, fire alarm, access control, CCTV and many more applications.

The user can select one of the following four modes by pressing the SET button, when the LED is flashing, this is the function the relay timer is set to, if the LED is constant this will allow change of mode function by pressing the SET button. The delay time can be selected by adjusting the potentiometer, the delay time can be adjusted between 0.1 second and 120 seconds.
 

Function 1:

Power-on, relay is off, after set time delay relay is turned on: Sending a high-level pulse signal to the X1 terminal at any time the relay turns off and starts timer after time delay the relay turns on. If the power removed function is reset as above.

Function 2:

Power-on, relay is on, after set time delay relay is turned off: Sending a high-level pulse signal to the X1 terminal at any time the relay turns on and starts timer after time delay the relay turns off. If the power removed function is reset as above.

Function 3: (no timer)

Latching relay mode: a high-level pulse signal is sent to the relay X1 terminal, the relay is turned on, and when a high-level pulse signal is sent to X1 terminal the relay is turned off.

Function 4:

Level trigger mode: When the power is turned on, the relay is off, when a high level signal is sent to the X1 terminal. The relay immediately turns on. After the X1 terminal signal is removed, the set delay time starts, when the time is reached the relay turns off. Sending a high level signal to X1 terminal during the set delay time resets the time delay count.

Features:

1. Selectable delay ON, delay OFF, latching and trigger delay functions.

2. Reverse polarity protection to prevent damaging the module.

3. Working voltage 12V DC Ideal for access control applications.

4. The delay time can be arbitrarily set between 0.1 seconds and 120 seconds.

5. The parameters can be saved, and the setting contents are not lost when power off.
