    Good board
  

*by C***1 on Reviewed in the United States on February 16, 2024*

Great board for the price. Used it as an introductory into the modbus world. In case anyone was wondering (as I was) how to actually utilize all of the relay modes, this is what you send in hex (decimal) to the corresponding address (register 1 being relay 1 and so on):Open - 100 (256)Close - 200 (512) Momentary/Toggle - 300 (768)Self-locking - 400 (1024) Interlock - 500 (1280) Delay - 600 (1536)When using a program like modpoll, make sure to send the command in (hex). And for some reason on modpoll, it does not like writing multiple relays at a time. If you write a program in visual studio, it has no problems though.
