1 Channel Delay Power-off Relay Module with Cycle Timing Circuit Switch

Features:
1. Wide voltage power supply (6~30V) supports micro USB 5.0V power supply, which is very convenient to use;
2. The interface is clear and simple, powerful, easy to understand, and almost meets all your needs;
3. One button emergency stop function (STOP button), with reverse connection protection, reverse connection does not burn;

5. Different OP, CL, LOP parameters can be set. These parameters are independent of each other and saved separately;

Description:
All setting parameters are automatically powered down and saved.
Special attention: The relay output is a passive contact, without a live output, to control the on/off of a line.
With optocoupler isolation, enhance anti-interference ability, industrial grade circuit board, Set parameters, and always remember after power failure.
