Pay attention: The module is an active output, the output voltage equal to the input voltage. 'DC + 'and' load + 'This is an internal short circuit of the poles, but' DC- 'and' load - 'poles during use can not be shorted, otherwise the load can not be controlled on and off, which is equivalent load is been carrying electricity. 0.1 seconds (min) to 999 minutes (max) continuously adjustable. 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 You can set a different OP, , parameters, which are of each other, and are automatically saved; After the module is powered down, all parameter settings are not lost. : 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 , reverse polarity 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 Colour: blue Material: PCB Size: 6 x 3.4 x 1.2cm Package Contents: 4 x Dual MOS tube control board Only the above package content, other products are not included. Note: Light reflection and different displays may cause the color of the item in the picture a little different from the real thing. The measurement allowed error is +/- 1-3cm.
