Description

The Teltonika TRB256 Industrial LTE Gateway is engineered for large-scale, mission-critical IoT and M2M deployments where reliability and protocol compatibility are paramount. Its multi-mode cellular radio supports LTE Cat-M1 and NB-IoT for low-power wide-area connectivity, alongside legacy EGPRS fallback, with specialized 450 MHz band support for enhanced building penetration and extended coverage in remote or dense urban areas.

Built around an industrial-grade architecture, the gateway provides dual SIM auto-failover for carrier redundancy, a 10/100 Mbps Ethernet port for local network backbone, and serial interfaces (RS232/RS485) for connecting legacy industrial equipment. Integrated support for Modbus, DNP3, BACnet, and MQTT allows seamless data aggregation and transmission to cloud platforms or on-premise SCADA systems without additional protocol converters.

Housed in a compact, ruggedized aluminum enclosure rated IP30, the TRB256 is designed for continuous operation in extreme temperatures from -40°C to +75°C. Advanced security features including VPN and firewall protection ensure data integrity for smart metering, utility monitoring, and critical infrastructure applications.

Key Features

  • Multi-mode cellular connectivity with LTE Cat-M1, NB-IoT (NB1/NB2), and EGPRS for flexible network deployment.
  • 450 MHz band support provides deeper signal penetration and extended coverage in challenging environments.
  • Dual Mini-SIM slots with automatic switching and backup WAN for uninterrupted network service.
  • Comprehensive industrial I/O: 10/100 Mbps Ethernet, RS232, RS485, and configurable digital/analog inputs/outputs.
  • Native industrial protocol stack including Modbus (RTU/TCP), MQTT, DNP3, BACnet, and DLMS/COSEM.
  • Advanced network security with integrated VPN (OpenVPN, IPsec), firewall, and access control lists.
  • Rugged, compact aluminum housing with IP30 rating for dust and splash protection.
  • Wide operating temperature range (-40°C to +75°C) and 9-30V DC input for harsh industrial settings.

Applications

  • Smart Metering (AMR/AMI) and utility remote reading systems.
  • Industrial IoT (IIoT) telemetry and remote monitoring of critical infrastructure.
  • SCADA and process automation with Modbus RTU/TCP or DNP3 protocol conversion.
  • Environmental monitoring and smart agriculture in areas with limited cellular coverage.
  • Fleet and asset tracking with reliable connectivity in harsh outdoor conditions.

Frequently Asked Questions

How do I configure the dual SIM failover on the TRB256?

Dual SIM auto-failover is configured via the built-in web interface or Teltonika's RMS platform. Navigate to the 'Mobile' settings, define the primary and backup SIM profiles, and set the failover trigger conditions (e.g., signal loss, data limit). The gateway automatically switches to the backup SIM, ensuring continuous connectivity for critical M2M applications without manual intervention.

What is the procedure for connecting Modbus RTU devices via the RS485 port?

Connect your Modbus RTU slave devices (meters, sensors) to the gateway's RS485 terminals (A+, B-). Using the web interface, configure the serial port parameters (baud rate, parity, stop bits) to match your device. Then, set up a Modbus RTU master instance within the gateway's protocol stack, define polling registers, and map the data to be forwarded via MQTT or stored locally for SCADA integration.

Can the TRB256 operate on both 12V and 24V DC industrial power supplies?

Yes, the TRB256 accepts a wide input range of 9-30V DC via its 2-pin terminal block, making it compatible with standard 12V and 24V DC industrial power systems commonly used in control panels, vehicles, and solar-powered installations. Ensure proper polarity and use a stable power source within this range to guarantee reliable operation in harsh environmental conditions.

How do I update the firmware and configure VPN settings on this gateway?

Firmware updates are performed by uploading a .bin file via the web interface under the 'System' > 'Firmware' section. For VPN setup (OpenVPN/IPsec), navigate to 'Services' > 'VPN', create a new tunnel profile by importing client certificates or configuring pre-shared keys, and assign the VPN interface to your desired data routing rules for secure remote access to your industrial network.
