Seamlessly Connect Industrial Sensors to LoRaWAN® with Manthink’s KC21 DTU

Struggling to modernize legacy industrial equipment without costly reengineering? Meet Manthink’s KC21, a battery-powered, waterproof LoRaWAN DTU that simplifies IoT integration for industrial environments.
With an optional DN20 mechanical interface, the KC21 can be directly mounted onto field devices like flow meters, enabling robust, weatherproof deployments in harsh conditions — from water treatment plants to remote energy sites.
🔌 Supports multiple analog & digital interfaces:
• 4–20mA / 0–10V signals
• RS-485 (Modbus, DL/T645, CJ/T188)
• M-Bus compatible
💧 Ideal for monitoring:
• Flow meters
• Temperature & humidity sensors
• Vibration detectors
• Pressure and level sensors
⚡️ Built-in Edge Intelligence via Edge-Bus (EB):
The KC21 runs business logic locally using JavaScript-like scripting, supports FUOTA updates, and enables COV reporting, alarm triggering, and data preprocessing — all without additional software development.
🔋 Power-constrained? No problem.
KC21 includes external power output (15V), allowing it to power connected sensors — eliminating the need for separate power cabling in hard-to-reach locations.
All data seamlessly integrates into ThinkLink, Manthink’s open LoRaWAN Network Server (NS), which supports global standards and offers powerful edge/cloud deployment flexibility.
