RS485-NB - RS485-Modbus/UART to NB-IoT Converter with SIM Card

The Dragino RS485-NB is a RS485 / UART to NB-IoT Converter for Internet of Things solutions. User can connect RS485 or UART sensor to RS485-NB converter, and configure RS485-NB to periodically read sensor data and upload via NB-IoT network to IoT server.

RS485-NB can interface to RS485-Modbus sensors, 3.3v/5v UART sensor or interrupt sensor. RS485-NB provides a 3.3v output and a 5v output to power external sensors. Both output voltages are controllable to minimize the total system power consumption.

This version has 1NCE SIM card pre-installed and is configured to send data to DataCake. You Just need to select the sensor type in DataCake and switch it on. Then you will see the measured values in DataCake on your computer or smartphone.

The SIM card has 500MB data volume and is valid for 10 years. The 1NCE NB-IoT service has coverage in most European countries. The current coverage can be checked on the website of 1NCE.

RS485-NB is powered by 8500mAh Li-SOCI2 battery for many years of use. It has an external antenna and an IP66 enclosure with a waterproof M12 cable hole for an external sensor.
