1. To achieve fast turn-on and off the circuit, an unlimited number of switching2. Conducting and cutting process does not produce noise, no spark, no electromagnetic interference3. Compared with electromagnetic relay products, longer life4. 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 equipment5. A method for controlling the motor, lights, LED, DC motors, -pumps, solenoid valves, etc., very convenientName: Relay Modulesize: 6.0 x 3.4 x 1.2cmcolour:BlueMaterial:PCBPackage Contents:2 x Trigger Cycle TimerOnly 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.
