Lora 4-20mA Reader

General Features:
1. It has 2-Channel 4-20 mA input
2. With the internal battery, it can perform readings every 5 minutes at specific intervals externally and continuously with a solar panel
3. It has a 12-24V 250mA external supply input.
4. It takes a reading once every 5 minutes and transmits the information to the center.
5. There is no data loss in case of power off and on.
6. The device has Lora modulation and LoraWan protocol with EU-868 Mhz frequency band and 14db output power.
7. It has an external antenna connection.
8. Configuration processes can be performed via the system.
9. Energy status, operating status, and alarm status can be monitored with the LEDs on it.
10. When the device is not sending data, it operates in Ultra Low Power and does not consume unnecessary energy.
