Product description
Interval Timer with Relay. It can be used to turn on and off a connected load at regular intervals. For instance, a warning light that blinks. The ON and OFF times can be individually set between 0.5 and 20 seconds using two potentiometers on the board.
The entire circuit is powered directly from the mains voltage via a capacitor and rectifier, eliminating the need for a separate DC power supply. Note that nothing external should be connected to the DC voltage on the board (i.e., no clever extra features should be added), and the entire board should be considered extremely hazardous when in operation!
The board must be enclosed in an insulating box, and all wires must be securely fastened to prevent detachment. A fuse must be installed in series with the incoming voltage. The fuse should be sized according to the load.
