Generic 2C20 Timer Module Trigger Delay Relay Module 5-30V Micro USB Power

MicroUSB 5.0V power supply, 5-30V wide supply voltage, External signal trigger, Key trigger, Relay indicator, Anti-interference ability, Adjustable delay time, Freewheeling protection, Enhanced anti-jamming capability, Controls 10A/250VAC and 10A/30VDC loads

Operating mode: In the initial state, normally open (NO) and common terminal (COM) are disconnected, normally closed (NC) and common terminal (COM) are connected. Provide a low pulse signal or touch trigger key to activate the relay and indicator lights. The output state changes: NO and COM connected, NC and COM disconnected. After 0-24 seconds (adjustable), the relay turns off and returns to the pre-trigger state. Timing adjustment is done by potentiometer (default 0-24 seconds). For longer times, replace capacitor (C2) or potentiometer (Delay time T = 1.1RC). The module can control 10A / 250VAC, 10A / 30VDC loads. Warnings: Use for delay powered vehicle equipment to prevent large currents from burning equipment during car start. Prevent simultaneous launch of multiple devices to avoid burning appliances or failure to start.
