Compact RS485 To WiFi Modbus Gateway

DIN rail mountable gateway in a compact lipstick-shaped enclosure (95 × 28 × 28 mm, ~120 g), supporting IEEE 802.11 a/b/g/n dual-band WiFi (2.4 GHz and 5.8 GHz). Integrates RS485 serial interface for Modbus RTU communication and delivers native Modbus TCP over wireless IP networks. Built for industrial environments with stable performance under variable RF conditions and thermal loads. Requires no external power adapters — powered directly via DIN rail (24 V DC typical). Enables transparent bridging between Modbus RTU slave devices (e.g., temperature sensors, energy meters, motor controllers) and Modbus TCP master systems (e.g., SCADA servers, HMIs, cloud gateways). Supports standard function codes (01, 02, 03, 04, 15, 16) and configurable polling intervals. All configuration performed via web interface or Modbus register writes — no CLI or software install needed. Deployed in factory floors for PLC-to-cloud telemetry, HVAC subsystems for wireless BMS integration, and remote substations for asset health reporting. Its small form factor allows mounting directly beside existing RTU devices — minimising cable runs and electromagnetic interference risks.
