Instructions for use

1. Power the module.

The module is powered by a 12 V DC voltage. Screw terminals are marked with VCC andGND.

WARNING! Be careful to observe the polarity, thus damaging the product.

2. Relay coupling.

The relay is coupled when the connection between the red-pinned pins is attached to the picture attached below and a configurable time is activated with the S1, S2 and S4 jumper and via the blue potentiometer marked TIME-ADJ. The green LED illuminates during the relay activation.

3. Setting the coupling time.

Refer to the attached table below to configure the relay switching time. Also, the relay is switched on when the green LED is on.

Example: In the attached picture below, jumper S1 is disconnected and jumper S2 is connected. Thus, the coupling time is between 0.13 seconds and 1.3 seconds. Then the time is adjusted with the blue potentiometer. The time decreases when it is rotated counterclockwise and increases when it is rotated clockwise.
