Delivered quickly and works great

I bought this for a home project to control my basement humidity and temperature Taxes. Modbus signals are easy to read and have been working properly for more than 2 months. I was torn when I saw the display, but I'm actually looking at it more than I expected. Thank you nine!

Pros
  • Up to 247 modules can be connected by changing RS485 address (more than 16 devices, RS485 repeater is recommended)
Cons
  • Some small things

no documentation

Supplied with cracked case and no documentation to change RTU address. We don't know how the registers are mapped and how to change the RTU address. Could you put the information in the product description or a convenient URL on the web. A slip of paper with this information included with the product would be of great help. We will return the item if we cannot figure out how to get the information.

Pros
  • DD4012SA voltage conversion sensor module, high efficiency, low heat voltage converter
Cons
  • Very expensive
