Multi-functional Timer delay module is a revolutionary circuit with many commonly used timer delay functions. It is perfect for many applications from hobby to industrial controls. The timer delay module allows delaying power, disconnecting power after a preset period, cycling, and many other functions. Time delay can be set from 0.1 seconds to 400 days. The circuit is utilizing an embedded microcontroller so the time delay is precisely repeated every time. Timer functions are loaded via a separately sold programmer. The programmer can load a set of standard functions as well as custom functions created based on the specific requirements. The circuit can support up to 10 amps. Timer delay module can be configured to delay power, supply power for a period of time or cycle power with preset delay and etc. With external relay control any current or voltage. Great for automotive application, car amplifier control delay, industrial controls, and hobby. We are confident timer will work for your project. Please contact us if you are not sure.
