I didn't receive any instructions on how to operate this device but luckily I was familiar with Waveshare products and knew they would have a wiki with software and example code. Search the web for “Waveshare Modbus RTU IO 8ch wiki” and it should be one of the top results. This wiki includes a download link for Windows software to control this device. It also includes all the commands for the device.I picked up a RS485 to USB adapter, also from Waveshare, and was able to communicate with the device on a Linux computer. The default baud rate is 9600 8N1. Note that you will need to be able to send HEX commands using serial, I found the program “moserial terminal” provides a nice graphical way to send and receive HEX data. It is also possible to write a Python script to interface with this device. The wiki includes sample code to get started.I wanted to see what IC’s were used for this device so I opened it up and included a few photos. The main microcontroller is a STM32F030C8T6. The digital outputs use a ULN2803A darlington transistor array capable of 500mA up to 50V. Optical isolators are used to isolate this and the STM32 micro. For digital inputs optical isolators are also used. There is an isolated 5V 1W DC-DC regulator and a gas discharge tube. This design is fully isolated and the circuitry looks nice and neat.Overall this is a great device that I would recommend for anyone looking for isolated digital IO.

El módulo «Módulo de entrada y salida digital Waveshare Industrial de 8 canales, fuente de alimentación de amplio voltaje DC de 7 ~ 36 V, circuitos de protección de aislamiento múltiple, soporte de montaje en riel»Se puede encontrar mucha información y documentación en la web del fabricante,Este módulo está diseñado para señales digitales de bswp. Capta los sensores y reenvíarlos a través de Modbus. Sin embargo, también se pueden emitir señales digitales, lo que hace que también sea adecuado para conmutar a través de RS485, por ejemplo, reléProducto fiable y estable.

Esta es solo mi opinión tras probar el producto. No tiene por qué coincidir con la de otras personas.Este es un buen modulo de E/S digitales para proyectos personales o profesionales. Comunicación por modbus rtu mediante rs485. Amplio rango de tensión de alimentación. Protección en las E/S.

Il dispositivo non funziona bene, presenta dei bug. Ne abbiamo acquistati 2 e sono uguali difettosi. non possono essere resettati anche se è indicato come effettuarlo non si resettano ritornando con i dati di fabrica. Abbiamo chiesto assistenza al costruttore ma le sue info non funzionano. inoltre il firmware nuovo non è accettato dal dispositivo. NON FATEVI FREGARE:
