Industrial LTE-M / NB-IoT Serial Modem – RS232/RS485 for Low-Power IoT
Industrial LTE-M/NB-IoT modem designed for low-power, long-range IoT applications. Supports RS232, RS485, Modbus RTU, transparent TCP/UDP, and up to 5 simultaneous data servers. Australian stock, local support, and compatible with ProSight or any third-party platform.
This Industrial LTE-M / NB-IoT Serial Modem is engineered for applications requiring strong signal penetration, low power consumption, and dependable long-range connectivity. Designed as a modern replacement for legacy GSM/GPRS modems, it delivers reliable serial-to-cloud communication using LTE Cat-M1 and NB-IoT networks — ideal for indoor, underground, rural and low-signal environments.
With RS232 and RS485 interfaces, the modem integrates easily with serial devices such as PLCs, meters, sensors, controllers, HVAC systems, building automation equipment, and environmental monitoring stations. Its industrial MCU and hardware protection ensure stable operation in harsh or remote conditions.
The modem supports transparent data transmission, Modbus RTU passthrough, TCP/UDP, and optional MQTT/COAP for modern IoT platforms. It can also upload data to up to 5 servers simultaneously, providing redundancy and multi-system integration.
Perfect for:
✔ Smart buildings & HVAC
✔ Underground or low-coverage assets
✔ Environmental monitoring
✔ Smart metering & utilities
✔ Industrial automation
✔ Low-power IoT deployments
✔ Migration from legacy GPRS/GSM systems
We keep stock in Australia, offer local tech support, and help integrate this modem with ProSight or any third-party IoT/cloud software.
