MOSFET Trigger Switch Module, Optocoupler PCB Isolation Delay Timer DC 5V to 30V 20A Adjustable from 0.1S to 999Min for Solenoid Valve Control

Optocoupler Isolation: This MOSFET trigger switch module uses optocoupler isolation to separate the input and output. It helps reduce interference in DC load control for PLC signal, PNP sensor, button trigger, and automation projects. Adjustable Delay Timer: The built-in delay setting supports 0.1-second steps from 0 to 99.9 seconds, 1-second steps from 0 to 999 seconds, and 1-minute steps from 0 to 999 minutes for flexible timing control. High Current Switching: Designed for 5V to 30V DC systems with a 20A current limit. For loads above 5A, add a heatsink. Suitable for switching LED strips, DC motors, micro water pumps, and solenoid valves. Power-Off Memory: The module saves the last configured delay after power-off, so No repeated configuration is necessary during daily use. Useful for repetitive circuit tasks in control panels and DIY electronics projects. PCB board for projects: Made of PCB material with an operating temperature range of -40°F to 185°F. The operating current is 50 mA and the standby current is 20 mA for embedded control and workshop applications.
