Module : 1. Wide voltage power supply (6-30V) supports -USB 5.0V power supply, which is convenient to use2. The interface is clear and simple, powerful and easy to understand, meeting all your needs3. One key emergency stop function (STOP key), with reverse connection protection, reverse connection will not burn4. Different OP, , parameters can be set, these parameters are of each other and saved separately5. All setting parameters are automatically saved after power off.Product parameters:1: Working voltage: 6- 30V, support -USB 5.0V power supply2: Trigger signal source: high-level trigger (3.0V-24V) signal ground and system ground are not common to the anti-interference of the system (you can also short-circuit the common ground by yourself)3: Output capacity: can control equipment within DC 30v 5A or AC 220v5A4: Static current: 20mA Working current: 50mA5: Service life: more than 100,000 ; working temperature: -40-85C;6: With optocoupler isolation, enhanced anti-interference , industrial-grade circuit board, set parameters forever after power off memory. attention: The relay output is a passive contact, with no power output, and it controls the on-off function of a line.type: relay modulecolor:BlueMaterial:PCBandelectronic componentsPackage Contents:1 x One way relay moduleOnly the above package content, other products are not included.Note: Light reflection and different displays may cause the color of the item in the a little different from the real thing.
