Supplied power is for the electronics only. You will need additional power source(s) - in addition to the power for the electronics -for the devices you are controlling via the relays/switches. **Q: What are the differences between 4ch, 4ch pro, 4ch r2 and 4ch r2 pro?** A: Just by looking at the pics and specs displayed it appears that the two 4CH units (WITHOUT PRO) use the same power source (90-220 AC) for the electronics AND the connected devices). Both the models with PRO use the supplied power ONLY for the electronics and you would supply power separately to the external devices controlled by the switches. **Q: What is the amperage limit / ampacity of this unit?** A: This is 10 amp /loaf with a wifi. & 433 MHz **Q: How do you change modes between interlocking, self locking and inching?** A: Hello that is done with the DIP switches. I don't have the manual in front of me but if you go to the webpage for the device you can get a PDF version. If I remember correctly it was better than the one on the box and clearly showed how to set them. ## Customer Reviews ### ⭐⭐⭐⭐⭐ As describe *by D***U on 7 February 2026* Working good ### ⭐⭐⭐⭐⭐ Review *by U***A on 12 September 2025* Exelente producto para automatizar el límite es tu imaginación tengo un año usando y funciona al 100 ### ⭐⭐⭐⭐⭐ Review *by C***S on 24 November 2022* Recebido no prazo e funcionando corretamente. ## Frequently Bought Together - SONOFF 4CH Pro R3 Wi-Fi Smart Switch 4-Channel Din Rail Mounting Home Automation,Self-Locking/Interlock Control Home Appliances, RF/APP/Voice/LAN Control, Works with Alexa(1 Pack) - SONOFF BASICR2 WiFi Switch 3-Pack Wireless Remote Control Electrical for Household Appliances,Compatible with Alexa DIY Your Home Via iPhone Android App --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.id/products/402194015-4ch-pro-r3-wi-fi-smart-switch-4-channel-din](https://www.desertcart.id/products/402194015-4ch-pro-r3-wi-fi-smart-switch-4-channel-din) --- *Product available on Desertcart Indonesia* *Store origin: ID* *Last updated: 2026-05-14*
