Dragino PS-NB-NA NB-IoT Analog Sensor Node (0–20 mA / 0–30 V, IP66)

The Dragino PS-NB-NA is an NB-IoT analog sensor node that connects traditional analog instrumentation to modern IoT systems—ideal when you want to keep proven sensors in the field and simply add connectivity. It reads common signals like 0–20 mA (widely used in industrial transmitters) and 0–30 V (typical for many analog outputs), converts them into digital data, and uploads measurements over NB-IoT to your platform.

A practical advantage is built-in sensor power: the PS-NB-NA provides 5 V and 12 V outputs, which can eliminate the need for separate power supplies in many deployments. It also supports multiple sampling with a single uplink, helping smooth readings and optimize transmission behavior. For integration, it supports several uplink methods—MQTT, MQTTS, TCP, and UDP—so you can match your backend and security requirements.

Deployment is field-friendly with BLE configuration, OTA firmware updates, and AT commands for parameter changes. The IP66 housing protects against dust and water jets, making it suitable for harsh environments. Some variants also offer an optional built-in SIM/default server connection option for simpler provisioning.
