product description: Multi-function Dual MOS Control Relay Cycle Timer Module Delay Time Switch DC 12 / 24V Components 0.1 seconds (minimum) to 999 minutes (maximum) continuously adjustable This product is easy to use, powerful, but all buyers a detailed look at the product instructions, very useful product. Features and application modules: 1. To achieve a high-frequency circuit fast frequent on-off switch unlimited number of times; 2. The on-off process does not produce noise, no spark, no electromagnetic interference; 3. life long life than conventional electromagnetic relay; 4. Dual MOS shunt active output, lower resistance, more current, strong power at room temperature, 15A, 400W, to meet the most use of the equipment; 5. often used to control motors, light bulbs, LED lights, DC motors, micro-pumps, solenoid valves, etc., through this module, you can easily control these devices, very convenient. Module Highlights: 1. Wide voltage (5 ~ 36V), most devices can be used, very convenient; 2. The interface is clear and simple, powerful, easy to understand, meet almost all your needs; 3. There is a key stop function (STOP key), with reverse polarity protection, reverse polarity does not burn; 4. Increase the sleep mode, enable, without any operation within 5 minutes, turn off the monitor automatically; Any key to wake up; 5. You can set a different OP, CL, LOP parameters, which are independent of each other, were saved; 6. When all settings automatic power-down save parameters.
