Key benefits Precise digital delay and cycle timing for repeatable automation of 12V loads. Simple integration with standard 12V DC power sources and common relays. External trigger input enables control from sensors, switches, or microcontrollers. Compact circuit board format suitable for enclosure mounting in tight spaces. LED indicators provide clear status visibility for power, trigger, and output activity. Efficient MOSFET driven output helps protect LED loads and reduces heat in the control path. Key attributes Functionality: digital delay timing with trigger capable cycle operation and relay output control. Compatibility: designed for 12V DC power supplies; drives relay loads and LED driven loads via MOSFET output. Size: compact circuit board module intended for easy integration into projects and enclosures. Material: circuit board based timing module suitable for inclusion in electronic assemblies. Performance: reliable, repeatable timing with clear LED status indicators for quick troubleshooting and monitoring. What it does Provides a digital delay between a trigger input and the subsequent activation of a relay or output load. Supports cycle timing to repeatedly switch the connected load on and off according to the programmed cadence. Includes status LEDs to indicate power, trigger activity, and output state for straightforward operation and diagnostics. Specifications highlights (based on the product model) Voltage: DC 12V operating supply. Control: digital delay with triggerable cycle timing. Output: relay drive output suitable for switching loads in 12V systems. Indicators: LED indicators on the module for status monitoring. Form factor: compact circuit board module for straightforward integration. Use cases Automatic lighting control: connect to a 12V LED lighting string or strip and use a sensor or switch as the trigger. The module delays turning on the light after trigger and can be set to hold the light on for a defined period, or to cycle on/off in a repeating pattern for signage or attention indicators. Small pump or fan control: in irrigation, circulation, or ventilation applications, use the trigger to start a 12V pump or fan after a delay, or to run it in a timed cycle to conserve power and reduce wear. Indicator or signaling circuits: drive an indicator panel or signaling lights with a timed on/off cycle to simulate status, create visual alerts, or test alert sequences in a controlled manner. How to use Connect a 12V DC power supply to the module and wire the trigger input to a switch or sensor. Connect the relay output to the load you need to control (ensuring the load is compatible with the relay rating). Configure the delay time and cycle settings as required for your application, and monitor using the onboard LEDs. The DC 12V MOS LED Digital Delay Relay Trigger Cycle Timer Delay Switch Circuit Board Timing Control Module provides a straightforward, dependable timing solution for projects requiring delayed activation, cyclic switching, and simple automation in a 12V DC environment. It is suitable for a range of applications from hobby experimentation to smallscale automation tasks, offering clear status indication, a compact form factor, and reliable digital timing performance.
