Review on Industrial Modbus RTU Relay Module by Aaron Masek
Does not meet Modbust timing requirements
You can force the relay to switch, but if you expect to read something from this device, you must ignore the minimum response time of 3.5 characters, since this device is responsible for 1 character. Waveshare support is useless.
Pros
- Solid onboard power supply isolation, provides stable isolated voltage, requires no additional power supply for the isolated port. Built-in magnetic unibody ADI isolation ensures signal isolation, high reliability, strong anti-interference and low power consumption.
Cons
- Something is wrong
