OONO DC 4.5-30V 10A Blinking Flasher Module, Normally Open | Adjustable ON/OFF Timing

Overview

Meet the OONO blinking flasher module, a compact DC-only timing device designed to add dynamic signaling to your project. It runs safely on a DC supply from 4.5 to 30 V and can drive up to 10 A, making it suitable for LED lamps, hazard lights, safety beacons, and similar indicators. With a normally open output, the circuit conducts when the timer is active, delivering a clear on/off cycle that you can tailor to your needs.

Two precise, 25-turn potentiometers let you set the ON and OFF intervals independently. The timing range spans from 0.01 to 15 seconds for each phase, enabling everything from subtle, occasional blinks to more noticeable, rapid signaling. An LED indicator provides immediate feedback on the current output state, so you can confirm activity at a glance.
