Description

The Teltonika TRB256 is an industrial-grade M2M gateway designed to provide reliable data transmission for utility and industrial applications. This compact device excels in challenging environments by supporting LPWA technologies, including NB-IoT and LTE Cat M1, with the addition of 450MHz frequency band support for enhanced signal penetration. By bridging RS232 and RS485 interfaces into a single cellular link, the TRB256 enables the modernization of legacy infrastructure in smart metering and grid management.

Industrial Connectivity Suite

Dual Serial Interfaces Equipped with both RS232 and RS485 ports to communicate with industrial PLCs, meters, and sensors.
Global LPWA Reach Supports a wide set of LTE Cat M1 and NB-IoT bands, including 450 MHz, for coverage at remote sites.
Flexible Digital I/O Features 3 pins that can be configured as either digital inputs or open-collector outputs for local automation.
RutOS & RMS Management Powered by Teltonika’s Linux-based RutOS, enabling secure remote monitoring through RMS.

Primary Industrial Uses

• Smart Grids & Metering: Connect and remotely read electrical or water meters via low-power cellular networks.
• Industrial Automation: Provide secure M2M connectivity for PLC systems in remote or underground sites using 450MHz.
• Environmental Monitoring: Aggregate serial data from weather stations or pollution sensors in off-grid locations.

Technical Integration

The TRB256 is housed in a durable aluminum shell and supports a wide power supply range of 9V to 30V DC. It features an integrated GNSS module for location tracking and timing synchronization. For security, the gateway supports multiple VPN protocols (OpenVPN, IPsec, WireGuard) and firewall functionalities.
