0.1 seconds (min) to 999 minutes (max) continuously adjustable. This product is easy to use, many functions, but all buyers need to carefully read the instructions, very useful product. Module characteristics and uses: To achieve fast turn-on and off the circuit, an unlimited number of switching; Conducting and cutting process does not produce noise, no spark, no electromagnetic interference; Compared with electromagnetic relay products, longer life; The dual-MOS parallel drive, lower resistance, more current, strong power; at room temperature, operating current of up to 15A, power up to 400W, to meet the most use of the equipment; A method for controlling the motor, lights, LED, DC motors, micro-pumps, solenoid valves, etc., very convenient. Highlights: Wide voltage input (5 ~ 36V), most devices can be used, very convenient; The interface is clear and simple, powerful, easy to understand, meet almost all your needs; The emergency stop function (“STOP” key);With reverse polarity protection, reverse polarity will not burn the product. Increase the sleep mode, if this mode is enabled, without any operation within 5 minutes, then automatically turn off the monitor, any key wake-up; You can set a different OP, CL, LOP parameters, which are independent of each other, and are automatically saved; After the module is powered down, all parameter settings are not lost. Operating mode: P1: trigger signal, the relay is on "OP" time, and then disconnect; in the "OP" time, as follows: P1.1: signal is triggered again, invalid P1.2: signal is triggered again, the clock is reset P1.3: Signal trigger again, relay off, stop the clock; P-2: trigger signal, the relay off "CL" of time, the relay on "OP" time, and then disconnect relay;
