TRB246 LTE Cat 4 Gateway

With the Teltonika TRB246—a protected 4G LTE Cat‑4 IoT gateway for machine-to-machine (M2M) communication in challenging environmental conditions—you may engage in safe industrial networking.

Key Specifications

• Connectivity: 4G LTE Cat‑4 (up to 150 Mbps DL / 50 Mbps UL), fallback to 3G and 2G networks.
• Dual‑SIM support: Automatic SIM failover to guarantee uptime under poor signal or limit conditions.
• Interfaces: 1 × 10/100 Mbps RJ45 Ethernet; RS‑232 and RS‑485 serial interfaces; 3 configurable digital I/O (logic input or open‑collector output) via 16‑pin terminal block.
• Protocol support: DNP3, Modbus (TCP & RTU), DLMS and others – essential for SCADA, energy, utility, and automation markets.
• Remote management: RutOS OS with secure WEB UI, FOTA updates, SNMP, MQTT, JSON‑RPC, TR‑069, VPN options (WireGuard, OpenVPN, ZeroTier, etc.) via Teltonika RMS.

Features & Benefits

• Rob.-des connectivity anywhere: Dual‑SIM with auto‑switch keeps devices connected even in case of mobile network failure.
• Small but strong: Rugged aluminium housing resists use between. –40 °C and 75 °C, with IP30 ingress protection—suitable for factory, field, or construction environments.
• Legacy + new: A combination of Ethernet, serial, and I/O. It allows for compatibility with both modern sensors and legacy devices.
• Built-in data protocols: It can easily get connected to established industrial data standards (BACnet, MQTT, Modbus, etc.).
• Scalable control: Teltonika RMS makes it simple to configure and remotely manage gateway fleets. It perfect for large-scale IoT rollouts.

Applications
Ideal for:

• Industrial automation and smart factories
• Pump, generator, meter, transport asset remote monitoring
• Construction site connectivity in high-vibration environments
• Environmental monitoring and agricultural telemetry
• Energy & utility SCADA integrations (DNP3 / DLMS / Modbus)

Technical Specifications

• Size: 83 mm × 25 mm × 74.2 mm (W×H×D) — tiny and DIN‑rail or wall mountable
• Weight: 165 g
• Power input: 9–30 V DC with back‑polarity and surge protection
• Power consumption: ~1.5 W idle, up to 3.5 W peak

Why it matters

As remote connectivity demand grows, the TRB246 offers industrial-grade performance without compromise or complexity. Its ability to bridge field devices, industrial conformance, and resistance to hostile environments makes the device a trusted solution for IoT specialists deploying real-world M2M applications.
