The Teltonika TRB series are industrial cellular gateways – smaller and more focused than full routers, designed for specific industrial connectivity tasks including serial-to-cellular bridging, Ethernet-to-cellular conversion, and cellular WAN with I/O. All TRB devices include an RMS credit and are fully RMS-compatible.
Industrial 4G LTE gateway with single Ethernet port and RS232/RS485 serial. Compact form factor for DIN rail or panel mounting in industrial enclosures.
TRB140 with added digital I/O for monitoring and control applications. Can trigger alerts or actions based on digital input state changes.
Dual-SIM 4G LTE gateway with voice module support. Used for cellular PSTN replacement applications – connects analogue telephone equipment to the cellular VoLTE network.
5G Sub-6 GHz industrial gateway. For applications requiring higher data throughput than 4G – edge computing, video surveillance, high-density IoT aggregation.
