Authentic User Feedback

🔧 Industrial Automation Engineer Reviews

⭐⭐⭐⭐⭐ James Carter - Automation Engineer, Midwest Manufacturing
"The Rievtech PR-26DC-DAI-RA-N has been a game-changer for our production line retrofit. The Modbus TCP integration allowed seamless communication with our legacy SCADA system, and the 10A relay outputs (Q7-QA) handle our conveyor motors without any external relays. Setup was surprisingly intuitive thanks to the LCD and rotary dial—my team had it programmed in under two hours. No more protocol converters or third-party gateways."

🏭 Small Factory Owner Reviews

⭐⭐⭐⭐⭐ Linda Patel - Plant Supervisor, Precision Components Inc.
"We needed a compact PLC that could manage both analog signals for temperature control and high-power switching for our presses. The dual analog and relay outputs on this unit are perfect. I especially appreciate the rugged front panel—we’ve had no issues with dust or accidental button presses in our车间 environment. It's been rock-solid for over six months now."

🛠️ DIY Industrial Hobbyist Reviews

⭐⭐⭐⭐☆ David Kim - Home Automation Enthusiast
"I bought the Base Model for my garage-based smart HVAC project. While I had to refer to the quick-start guide a few times, the F1-F4 buttons and central dial made navigation much easier than expected. The 0–10V analog output lets me precisely modulate my fan speeds, and the relay handles the compressor just fine. Only reason I didn’t give 5 stars is the lack of built-in Wi-Fi—but honestly, that’s not what this device is for."

🏆 Industry Expert Recommendations

Industrial Control Systems Expert Recommendation

Dr. Alan Zhou - Senior Automation Consultant, IEEE Member
"In my assessment of mid-tier PLCs for Industry 4.0 readiness, the Rievtech PR-26DC-DAI-RA-N stands out for its modular expandability and dual AC/DC relay support. Its Modbus over Ethernet implementation is robust and well-documented, making it ideal for facilities transitioning from legacy systems. For small to mid-scale automation, this is a smarter investment than over-spec’d high-end models."

Manufacturing IoT Specialist Recommendation

Maria Gonzalez - IoT Integration Lead, SmartFactory Solutions
"What impresses me most is the expansion slot compatibility—we’ve already added a digital I/O module for predictive maintenance sensors. Combined with the 10A relay capacity, this PLC delivers industrial-grade performance in a compact form. It’s become our go-to recommendation for clients implementing edge-level control in retrofit scenarios."
