TELTONIKA Solutions: Industrial IoT Routers, Gateways & Connectivity Hardware

TELTONIKA builds hardware for specific deployment environments rather than adapting general-purpose networking equipment for industrial use. The core product philosophy centers on ruggedized form factors, purpose-built interfaces, and a unified management layer across the entire portfolio. The range extends beyond industrial IoT routers to include gateways like the TRB245 with digital I/O and GNSS for serial-to-cellular conversion, low-power LTE Cat M1/NB-IoT gateways like the TRM255 for sensor telemetry, and industrial managed switches such as the TSW212. The TSW212 delivers 8 Gigabit Ethernet ports with 2 SFP slots in a compact industrial form factor, addressing edge switching requirements where space and durability constraints exclude standard enterprise switches. Each device category targets a distinct connectivity problem while sharing a common operating system and remote management infrastructure. Engineering teams therefore standardize on one management plane across routers, gateways, and switches deployed across multiple sites, reducing operational complexity without compromising deployment-specific hardware requirements.

RUTOS serves as the single firmware layer running across the entire TELTONIKA router and gateway portfolio, from the TRBIoT gateway to the RUTC50 5G edge router. This unified approach means configuration logic, firewall rules, and failover policies transfer directly between device categories without relearning a separate management interface per product line. RUTOS exposes advanced load balancing and carrier failover configuration natively, allowing engineers to weight WAN interfaces by capacity rather than relying on simple primary-backup switching. The operating system integrates with TELTONIKA Remote Management System (RMS), a cloud-based controller that handles batch firmware updates, configuration templates, and monitoring across deployed fleets. RMS licensing scales in point-based increments, with prepaid packages available at 1800 points for multi-device estates. On the hardware side, RUTOS drives protocol stacks for Modbus, DLMS, DNP3, and OPC UA directly at the edge, eliminating the need for a separate protocol gateway in field deployments. The firmware also supports VPN tunneling standards including WireGuard, OpenVPN, and IPsec for encrypted backhaul over cellular links.

The TELTONIKA RUT series spans several 5G industrial router variants differentiated by modem count, Wi-Fi generation, and regional band coverage. The RUTM52 family includes the RUTM5210B000, a ruggedized dual-5G-modem router running Wi-Fi 5 across five Gigabit Ethernet ports with native support for Modbus, DLMS, DNP3, and OPC UA industrial protocols. The RUTC50 targets ultra-high-throughput fixed-site deployments with Wi-Fi 6 and 4G Cat 20 backward compatibility, while the RUTC54 positions as a global 5G edge router with integrated eSIM for multi-region carrier flexibility. Each model shares the RUTOS firmware, meaning VPN, load balancing, and failover configurations remain consistent across the RUT lineup. The RUTM5210B000 distinguishes itself from the RUTC50 through dual independent 5G modems enabling simultaneous carrier bonding rather than single-modem failover — a critical difference for sites requiring guaranteed uptime rather than best-effort redundancy.

The TELTONIKA ATRM50 is a rugged 5G transport router built with M12 connectors and certified to EN 50155 (railway electronic equipment) and EN 45545-2 (fire safety). These certifications qualify the ATRM50 for deployment in rolling stock and heavy-transport environments where vibration, shock, and fire-propagation standards are mandatory. The ATRM50 delivers 5G Sub-6 GHz connectivity in both SA and NSA architectures, with 4G LTE Cat 19 fallback and 3GPP Release 16 support. Four M12 Gigabit Ethernet ports — one WAN, three LAN — provide physical connectivity resistant to vibration-induced disconnection. Dual-SIM with eSIM supports up to seven carrier profiles with automatic failover. Wi-Fi 5 (802.11ac Wave 2) operates in dual-band MU-MIMO mode, handling up to 150 simultaneous client connections. GNSS positioning integrates GPS, GLONASS, Galileo, BeiDou, and QZSS. Serial interfaces include RS-232/485 and digital I/O, with CAN available on select ATRM50 models.

The TELTONIKA TRBTRM255 serve as compact industrial LTE gateway devices engineered for machine-to-machine telemetry where digital I/O control is a hard requirement. The TRB245 delivers LTE Cat 4 throughput with integrated digital I/O and GNSS positioning, making the gateway suitable for remote asset monitoring and serial-to-cellular bridging in industrial environments. The TRM255 targets low-power, wide-area deployments using LTE Cat M1, NB-IoT, and EGPRS connectivity, pairing dual digital input/output channels with the same RUTOS management framework as the broader TELTONIKA router portfolio. Both gateways translate physical relay or sensor states into IP-based telemetry streams without requiring a separate protocol converter. For integrators connecting PLCs, meters, or environmental sensors over Modbus or RS-232/485, the TRB245 and TRM255 provide a single enclosure that handles cellular uplink, digital I/O interfacing, and VPN tunneling back to a control center.

ASCEND maintains TELTONIKA inventory across both hardware and software layers, allowing integrators to receive routers, gateways, switches, and management licensing in a single fulfillment cycle. ASCEND holds RMS prepaid licensing and WebTacho subscriptions alongside physical hardware, eliminating the delay where devices arrive but remote management or tachograph platforms remain unprocured. The Teltonika WebTacho license covers 20 devices for 1 year, enabling fleet operators to activate monitoring without a separate ordering cycle. ASCEND tracks TELTONIKA units by SKU and firmware revision, ensuring partners receive consistent RUTOS versions across batch shipments — a critical factor when deploying fleets of RUTM52 VDC units where mixed firmware creates configuration drift. For MSPs running multi-site rollouts, ASCEND provides allocation forecasts based on partner project pipelines rather than reactive restocking, reducing lead-time variability on high-demand SKUs.

Choose the TELTONIKA RUTM52 VDC when a fixed industrial site requires router-class throughput, multi-WAN failover, and local Ethernet switching rather than single-link gateway telemetry. Gateway-class devices such as the TRB245 and TRM255 serve narrow-band IoT endpoints where LTE Cat-4, Cat-M1, or NB-IoT data volumes are low and a single WAN interface suffices. The RUTM52 adds dual 5G/LTE modems with digital I/Os, enabling active load balancing across two cellular carriers — a capability gateway-class hardware cannot match. The RUTC50 shifts the access layer to Wi-Fi 6 and provides five Gigabit Ethernet ports, suiting sites with dense local client populations or on-premises equipment requiring wired backhaul. Both RUTM52 VDC run RUTOS, supporting industrial protocols including Modbus, DLMS, DNP3, and OPC UA, whereas gateway-class units typically bridge a single serial or Ethernet endpoint to the cellular network. For fixed installations where downtime carries operational cost — manufacturing floors, substations, water treatment plants — the dual-modem RUTM52 or the Wi-Fi 6 RUTC50 eliminates the single-link failure mode inherent to gateway-class deployments.

The TELTONIKA ATRM50 is purpose-built for rail deployments requiring EN 50155-certified networking hardware with vibration-resistant M12 connectors. The EN 50155 standard governs electronic equipment used in railway rolling stock, covering shock, vibration, temperature, and electromagnetic compatibility. The ATRM50 meets this standard alongside EN 45545-2 fire safety compliance, making the router valid for installation in passenger carriages, locomotives, and track-side vehicles. The four M12 Gigabit Ethernet ports (1 WAN, 3 LAN) provide threaded-locking connectivity that resists disconnection from mechanical vibration — a failure mode common with RJ45 connectors in rail environments. For carrier redundancy across cross-border rail routes, the ATRM50 supports Dual-SIM plus eSIM with up to 7 carrier profiles and automatic failover, eliminating manual SIM swaps when trains traverse national borders. The router also integrates RS-232/485 serial interfaces and CAN bus support (model-dependent), enabling direct communication with legacy train control systems and telemetry sensors without external protocol gateways. GNSS positioning draws on GPS, GLONASS, Galileo, BeiDou, and QZSS constellations for continuous location tracking in tunnel and urban canyon scenarios.

The TELTONIKA TRM255 operates as an NB-IoT gateway combining LTE Cat M1, NB-IoT, and EGPRS in a single industrial enclosure, targeting sensor networks where devices transmit small payloads at long intervals and broadband throughput is unnecessary. LTE Cat M1 supports mobile IoT endpoints with moderate data requirements. NB-IoT optimizes for stationary, deep-indoor sensors prioritizing battery life over bandwidth. EGPRS provides 2G fallback where LPWAN infrastructure is absent, extending deployment viability in rural or legacy-network regions.

The TRM255 integrates digital I/O directly, allowing discrete sensors and actuators to connect without an external PLC or controller. A single TRM255 aggregates telemetry from connected inputs and forwards data over the most available narrow-band bearer — reducing hardware count at remote monitoring sites. TELTONIKA RMS Prepaid licenses (1800 points) enable remote configuration and monitoring of TRM255 fleets across geographically dispersed sensor installations.
