Great product does what it says
Does what it should, but the online documentation lacks clarity, and not just the normal start address of 0 or 1 (JBus/Modbus), but with a bit of playing its soon sorted. A nice touch is the LED indicators for the relays and DI's.

Un nome una garanzia
Il Modulo Relay Modbus RTU Waveshare 8 Canali è una soluzione eccellente per chi necessita di un controllo remoto affidabile di carichi elettrici tramite il protocollo Modbus RTU. Questo dispositivo offre versatilità e robustezza, rendendolo adatto per applicazioni in ambito industriale, automazione domestica e altri scenari che richiedono un controllo preciso e centralizzato. La qualità costruttiva del modulo è solida, con un design compatto che facilita l'integrazione in quadri elettrici o in sistemi esistenti. I relè offrono una capacità di commutazione di 10A a 250V AC o 30V DC, il che li rende sufficientemente potenti per controllare una vasta gamma di dispositivi, dalle luci ai motori, passando per le valvole. Durante l'uso, il modulo ha dimostrato una grande affidabilità. La comunicazione tramite RS485 è stabile, e i comandi vengono eseguiti con precisione. L'isolamento optoelettronico integrato protegge il modulo da interferenze elettromagnetiche e sovratensioni, garantendo un funzionamento sicuro e continuo anche in ambienti difficili. L'unico possibile svantaggio è che richiede una conoscenza di base del protocollo Modbus RTU e delle reti RS485 per essere configurato e utilizzato correttamente. Tuttavia, per gli utenti con un minimo di esperienza in questi campi, il modulo risulta abbastanza intuitivo. Il Modulo Relay Modbus RTU Waveshare 8 Canali è un dispositivo versatile, affidabile e ben progettato, ideale per chi cerca una soluzione robusta per il controllo remoto di carichi elettrici. Grazie alla sua facilità di configurazione e alla compatibilità con il protocollo Modbus, rappresenta una scelta eccellente per una vasta gamma di applicazioni di automazione.

Fonctionne correctement
Ce module relay contrôlable via des ports série RS-232 / RS-485 est de bonne qualité de fabrication et fonctionne. Ce n'est certes pas le genre de modules le plus facile à utiliser mais la documentation est fournie sur le wiki et c'est un trait inhérent à ce genre d'appareils inspiré du domaine industriel.

Relaismodul war am Anfang etwas schwierig zu konfiguieren, da sollte man echt Ahnung haben! Ansonsten Modbus läuft stabil. Beleuchtung der Raumbediengeräte kann damit 1a gesteuert werden + Jalousien.

Great gadget.
We added the Waveshare Industrial Modbus RTU 8-Ch Relay Module to our setup, and it's been performing well. It’s built solidly and doesn’t feel flimsy like some other modules we’ve tried. With 8 channels, it's handling everything we throw at it, which is a lot when you’re running multiple systems. The RS485 interface is straightforward, making integration with our setup pretty painless. The multi-isolation protection circuits are a nice safety net, especially when you’re working with varied loads and power supplies. Speaking of power, the 7~36V range gives you some flexibility, which is helpful in our slightly chaotic environment. The digital inputs are responsive, and the module has been reliable so far. We haven’t had any hiccups, which, trust me, is a relief. If only everything else we worked with was this dependable! It's a solid choice if you need something reliable and not too fussy. It’s been quietly doing its job in the background—just the way I like it.
