433MHz RS232 RS485 Wireless Digital Radio E610-DTU(433C30) 30dbm 10KM Auto Relay Trunking Continuous High-Speed Transmission

The E610-DTU(433C30) is a 433MHz industrial wireless modem with RS232/RS485 interfaces, engineered for long-range, reliable data links. It supports automatic relay networking in general mode with multi-level relays for extended distances and can run multiple networks simultaneously in the same area. Designed for continuous high-speed transmission and automatic trunking, it offers flexible integration for telemetry and industrial data collection. Key communications and RF features: built-in PA+LNA+SAW, transmit power 30dbm and theoretical communication range up to 10km under ideal conditions; data rates supported from 0.5k to 470kbps; provides RSSI signal-strength indication to assess link quality and assist in network tuning and ranging. Frequency stability is ensured by a temperature-compensation circuit with stability better than ±1.5PPM. Power, consumption and connections: accepts 8 to 28V input and supports power-supply setter or crimping wiring methods; the 12V supply watchdog current is only 16mA and transmit current ≤ 0.4A. Multiple protection mechanisms are included — power-reverse protection, over-connection protection and antenna surge protection — to improve resilience in field environments. Mechanical and environmental: compact all-aluminum-alloy enclosure with efficient heat dissipation and careful shielding for strong electromagnetic compatibility and anti-interference performance. Rated for industrial operation across -40℃～+85℃, making it suitable for harsh conditions. Software and security: extensive programmable parameters (power, frequency, air rate, address ID, etc.) are configurable via software. Parameters are retained on power-down so the unit resumes with prior settings after reboot. A built-in watchdog with precise timing will restart the device on fault and preserve operation according to saved parameters. The module also supports a user-set communication key that cannot be read, enhancing data confidentiality. Overall, the E610-DTU(433C30) combines industrial-grade hardware, versatile serial interfaces (RS232/RS485), robust protections and flexible software control for reliable, long-distance wireless data transmission.
