1. Newly upgraded to version 2.0, the module functions have been increased from the previous 8 to 18 to meet more application needs;2. Increase the anti-reverse connection function of the power supply, so that the module will not be damaged due to wrong power connection;3. The use of high voltage power supply module to replace the previous discrete power supply, the system is more stable and reliable;4. Add 0.1 second timing function, the timing accuracy is upgraded from 0.1 second to 0.01 second;5. Increase the automatic power saving function, the user can set independently.FRM01 multi-function relay control module is specially designed for users with different needs. It uses a microcontroller as the main control unit with 18 preset functions, and can customize and add other specific functions according to user needs.The module adopts high-quality power relays, high-power and high-voltage triodes, red and blue signal indicators, and double-sided PCB boards. The layout is comprehensive and the performance is stable, which can be widely used in various power control occasions.Material: PCBcolour: As shownPackage Contents:1 x display Relay moduleOnly the above package content, other products are not included.Note: Light and different displays may cause the color of the item in the picture a little different from the real thing.
