Long range Data Transmission Radio Micro DIN-rail DTU
The EWD95M-2G4H27(485) is a compact, industrial-grade wireless digital transmission unit (DTU) designed for reliable, long-range serial data communication over the 2.4 GHz band. Built on a high-performance E34-T series module, it combines strong anti-interference capabilities, automatic frequency hopping, and wide-voltage support for versatile IoT and automation applications.
Wireless Communication
- Operating Frequency: 2.4 – 2.518 GHz (default 2.4 GHz)
- Transmit Power: 27 dBm
- Typical Communication Distance: up to 5 km in open environments
- Automatic Frequency Hopping: enhances anti-interference performance and link reliability
- Transparent Data Transmission: supports raw data pass-through serial communication without protocol overhead
Robust and Reliable Design
- Interfaces Supported: RS485
- Packet Retransmission: automatically handles packet loss to boost data integrity
- Anti-Interference Capability: advanced modulation and frequency hopping improve noise resilience
- Delay-Optimized: minimal communication latency suitable for real-time monitoring systems
Industrial-Ready Build
- DIN-rail Mountable: easy installation in control cabinets and industrial racks
- Wide Voltage Input: 8–28 VDC (ideal for automotive, industrial, and PLC systems)
- Rugged Shell: three-proof coating provides resistance to fungus, humidity and salt spray — perfect for harsh environments
- Compact & Lightweight: 80 × 28 × 28.5 mm at only ~32 g enables flexible placement
Typical Use Cases
✔ Industrial IoT gateways and sensors
✔ Remote data acquisition systems (SCADA / telemetry)
✔ PLC communication and automation networks
✔ Environmental monitoring (weather, water, gas)
✔ Building automation and energy management
This module fits seamlessly into systems where wired infrastructure is costly or impractical — providing a resilient wireless link for serial-based data streams.
