Review on 8 Channel Relay Module Board For Raspberry Pi 4B/3B+/3B/2B/A+/B+/Zero by Ray Sheptock
Good for environmental monitoring
Connected to my Raspberry Pi and the example code worked without any modifications. One day the developers gave me a written license for the code, modified it to monitor Nagios and it worked like clockwork.
- Bottom housing for standard rail mounting. Built-in LEDs to indicate relay status. The relay control contact selection jumper allows the relay to be controlled with user-defined contacts other than the standard contacts. Reserved control interface, allows working with PLC controls.
- Could have chosen a newer model
