FRM01 Relay Module Timing/Delay/Cycle/Self-lock Multi-function Relay Control PCB Board

Features:
Newly upgraded to version 2.0, and the module functions are increased from 8 to 18 to meet more application requirements.
Increase the anti reverse connection function of power supply, so as not to damage the module due to the wrong connection of power supply.
High voltage power supply module is adopted to replace the previous discrete power supply, making the system more stable and reliable.
Add 0.1s timing function, and the timing accuracy is upgraded from the previous 0.1s to 0.01s.
Automatic power saving function is added, and you can set it independently.
Using microcontroller as the main control unit, high power high voltage transistor, the performance is stable.
