Featuring 16 relay channels capable of switching up to 10A loads, it supports multiple relay modes and MODBUS RTU serial communication for seamless integration. With low standby power and scalability up to 64 devices, it’s ideal for industrial control cabinets, test benches, and complex DIY projects requiring reliable, flexible switching of AC/DC equipment. ## Description DC 12V 16 Channel MODBUS RTU RS485 Relay Module Board PLC Controller Serial Port Switch: desertcart.com: Industrial & Scientific Review: No documentation - The product seems very good very well packaged. The only problem it has no documentation neither information where to download the command instructions. Review: Good board - Great board for the price. Used it as an introductory into the modbus world. In case anyone was wondering (as I was) how to actually utilize all of the relay modes, this is what you send in hex (decimal) to the corresponding address (register 1 being relay 1 and so on): Open - 100 (256) Close - 200 (512) Momentary/Toggle - 300 (768) Self-locking - 400 (1024) Interlock - 500 (1280) Delay - 600 (1536) When using a program like modpoll, make sure to send the command in (hex). And for some reason on modpoll, it does not like writing multiple relays at a time. If you write a program in visual studio, it has no problems though. ## Features - [10A CONTACT RATING] Built to switch demanding loads with confidence. Each relay supports up to 10A at 250VAC 125VAC 30VDC 28VDC or 12VDC making it suitable for lights fans motors cameras and other equipment. - [MODBUS RTU CONTROL] Supports MODBUS RTU command control through RS485 serial communication. Commands can be sent by HyperTerminal serial assistant Modbus Poll PLC or MCU giving flexible integration in automation tasks. - [16 CHANNEL SWITCHING] This 16 channel relay module supports open close momentary self locking interlock and delay modes. Delay time can 255 seconds to match timing control needs in many projects and systems. - [12V DC POWER INPUT] Designed for DC 12V operation with low 11mA standby current. In MODBUS command mode the board can support up to 64 devices in parallel which is practical for scalable control networks. - [WIDE APPLICATION USE] Ideal for PLC automation control cabinets test benches and DIY industrial projects. It can control DC 12V loads directly and also switch DC 1 to 100V or AC 85 to 265V loads with extra 12V supply. ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B07YXV9Z16 | | Best Sellers Rank | #302,470 in Industrial & Scientific ( See Top 100 in Industrial & Scientific ) #68 in Programmable Logic Circuits | | Brand | FTVOGUE | | Brand Name | FTVOGUE | | Coil Voltage | 12 volts | | Connector Type | Screw, Pins | | Contact Current Rating | 10 A | | Current Rating | 10 A | | Customer Reviews | 4.0 out of 5 stars 5 Reviews | | Item Weight | 0.22 kg | | Manufacturer | FTVOGUE | | Maximum Switching Current | 10 A | | Maximum Switching Voltage | 12 volts | | Minimum Switching Voltage | 12 volts_of_direct_current | | Mounting Type | Surface Mount | | Operation Mode | Automatic | | Part Number | FTVOGUEta0m8cf93h | | Specification Met | Ma | | UPC | 705989626523 | | Unit Count | 1 Count | | Wattage | 120 watts | ## Images ![DC 12V 16 Channel MODBUS RTU RS485 Relay Module Board PLC Controller Serial Port Switch - Image 1](https://m.media-amazon.com/images/I/614IXEZasXL.jpg) ## Customer Reviews ### ⭐⭐⭐ No documentation *by M***S on February 21, 2025* The product seems very good very well packaged. The only problem it has no documentation neither information where to download the command instructions. ### ⭐⭐⭐⭐⭐ Good board *by C***1 on February 16, 2024* Great board for the price. Used it as an introductory into the modbus world. In case anyone was wondering (as I was) how to actually utilize all of the relay modes, this is what you send in hex (decimal) to the corresponding address (register 1 being relay 1 and so on): Open - 100 (256) Close - 200 (512) Momentary/Toggle - 300 (768) Self-locking - 400 (1024) Interlock - 500 (1280) Delay - 600 (1536) When using a program like modpoll, make sure to send the command in (hex). And for some reason on modpoll, it does not like writing multiple relays at a time. If you write a program in visual studio, it has no problems though. ### ⭐⭐⭐ Works, but tricky to make it work. *by D***Y on October 16, 2025* Decent PCB design and quality, however documentation for the RS485 is very limited and support from manufacturer would be highly appreciated. I had to spend a lot of time trying to figure things out. On the other hand, this was my first experience with Modbus, so that can be a problem as well. However documentation you can find is not very clear. In the end, board works fine. --- ## Why Shop on Desertcart? - πŸ›’ **Trusted by 1.3+ Million Shoppers** β€” Serving international shoppers since 2016 - 🌍 **Shop Globally** β€” Access 737+ million products across 21 categories - πŸ’° **No Hidden Fees** β€” All customs, duties, and taxes included in the price - πŸ”„ **15-Day Free Returns** β€” Hassle-free returns (30 days for PRO members) - πŸ”’ **Secure Payments** β€” Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** β€” Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.be/products/180576087-dc-12v-16-channel-modbus-rtu-rs485-relay-module-board](https://www.desertcart.be/products/180576087-dc-12v-16-channel-modbus-rtu-rs485-relay-module-board) --- *Product available on Desertcart Belgium* *Store origin: BE* *Last updated: 2026-08-24*
