Ebyte E90-DTU(230SL30) 230MHz 30dBm Industrial Grade Wireless LoRa Wireless Data Transceiver Modem - RS232/RS485 Intreface - 10km Communication Range

Ebyte E90-DTU(230SL30) 230MHz 30dBm Industrial Grade Wireless LoRa Wireless Data Transceiver Modem - RS232/RS485 Intreface - 10km Communication Range

E90-DTU (230SL30) is a data transceiver with military-grade LoRa modulation technology.The shell adopts three-proof coating, which is Anti-Fungal, Anti-Humidity, and Anti-Salt Spray. With multiple transmission modes, it works in the (220.125~236.125MHz) frequency band (Default 230.125MHz). The transceiver provides transparent RS232/RS485 interface and supports 8~28V voltage input.

Datasheet

Features

• All core components are imported, featuring the most advanced functions, the smallest volume and the best price.
• Using military-grade LoRa modulation technology, with data encryption, the packet length is available for configuration.
• Large single package, single package is up to 240 bytes, adapt to Modbus.
• Simple and efficient power supply design, support power adapter or crimping mode, support 8~28V power supply.
• Transmit power is up to 1W, multi-level adjustable, with all technical indicators meeting European industrial standards.
• Support LBT function, the transceiver automatically waits to send data according to the current ambient noise intensity. Thecommunication success rate of the module in harsh environments is greatly improved.
• Remotely configure or read wireless module parameters by sending command packets wirelessly.
• Multi-level relay networking can be realized, which effectively extends communication distance for ultra-long-distancecommunication. 
• With temperature compensation circuit, the frequency stability is better than ±1.5PPM.
• Operating temperature range: -40°C ~ +85°C, to adapt to a variety of harsh working environment.
• All-aluminum alloy casing, compact size, easy installation and good heat dissipation; perfect shielding design, withgoodelectromagnetic compatibility and strong anti-interference ability.
• Multiple protection functions such as power reverse connection protection, over-current protection, and antenna surge protectiongreatly increase the reliability of the device.
• Powerful software functions, all parameters can be programmed: such as power, frequency, air data rate, address ID, etc.
• Ultra-low power consumption, the standby current is only 10mA (lower than power consumption in power-saving mode andsleepmode), and the transmitting current is ≤0.1A.
• with built-in watchdog and precise time layout, once an exception occurs, the transceiver will automatically restart, and continuetowork according to the previous parameters.
