Waveshare Industrial Modbus RTU 8-channel Relay Module RS485 Bus With Power Adapter
This is an industrial 8-ch relay module controlled via RS485 bus, utilizing Modbus RTU protocol. It features embedded protection circuits such as power isolation, ADI magnetical isolation, TVS diode, etc. It also comes with an ABS enclosure. The Modbus RTU Relay is very easy to use. Due to its fast communication, stability, reliability, and safety, it is an ideal choice for industrial control equipment and/or applications with high communication requirements.
- Configurable device address (1~255), multi-devices can be cascaded on RS485 bus
- Features flash-on, flash-off functions, by passing an argument to the command, it is possible to turn on the relay for a while and then close it automatically
- Onboard unibody power supply isolation, provides stable isolated voltage, needs no extra power supply for the isolated terminal
- Onboard unibody ADI magnetical isolation, allows signal isolation, high reliability, strong anti-interference, low power consumption
- Support MQTT gateway function.
- Support JSON to Modbus RTU and 645 instrument protocol, support HTTP POST, and HTTP GET format to upload data.
