Robust Industrial 4G LTE Gateway for Critical M2M Communication
The Teltonika TRB246 is a versatile and rugged industrial 4G LTE gateway engineered for mission-critical machine-to-machine (M2M) and Internet of Things (IoT) applications. Encased in a durable aluminum housing, the TRB246 is built to withstand extreme environmental conditions, making it the ideal connectivity solution for manufacturing, agriculture, smart city, and industrial automation sectors. It provides reliable, secure, and seamless cellular connectivity for legacy and modern industrial equipment through its rich set of interfaces, including RS232, RS485, Ethernet, and a wide range of digital and analog I/Os.
Key Features for Uninterrupted Connectivity
- 4G LTE Cat 4 Connectivity: Delivers high-speed cellular communication with speeds up to 150 Mbps download and 50 Mbps upload, ensuring efficient data transmission.
- Dual SIM with Auto-Failover: Features two SIM card slots to provide redundant connectivity. It can automatically switch between operators in cases of weak signal, data limits, or network failure, guaranteeing continuous operation.
- Legacy Protocol Support: Equipped with essential serial interfaces (RS232 & RS485) and support for industrial protocols like Modbus, DNP3, and DLMS, allowing for seamless integration with a wide array of industrial machinery.
- Versatile I/O & Ethernet: A 16-pin terminal block offers configurable digital and analog inputs/outputs, while a 10/100 Mbps Ethernet port provides reliable wired connectivity.
- GNSS Positioning: Integrated GPS, GLONASS, BeiDou, Galileo, and QZSS capabilities allow for precise location tracking and geofencing applications.
- RutOS & Remote Management: Powered by RutOS, a secure and feature-rich operating system based on OpenWrt. The gateway is fully compatible with the Teltonika Remote Management System (RMS) for convenient monitoring and control of your entire device fleet.
- Industrial-Grade Durability: Designed with a rugged aluminum housing and an IP30 ingress protection rating, it operates reliably in a wide temperature range from -40 °C to 75 °C.
