Mission-Critical Connectivity for Industrial IoT

In the world of industrial IoT, unwavering connectivity is not a luxury—it's a necessity. The Teltonika TRB256 is a robust industrial cellular gateway engineered to provide reliable, high-performance networking for your most critical applications. Designed specifically for smart metering, industrial automation, remote monitoring, and telemetry, this gateway ensures secure and uninterrupted data transmission. Its rugged aluminum housing and wide operating temperature range make it the ideal solution for harsh industrial environments.

Unparalleled Reliability & Versatility

The TRB256 is equipped with 4G LTE Cat M1 and NB-IoT connectivity, with a fallback to EGPRS (2G), ensuring stable, long-range communication. A key feature is its Dual SIM functionality with auto-failover, which provides essential redundancy and backup WAN capabilities to keep your systems online and minimize downtime. This gateway also supports the 450 MHz frequency band, offering superior signal penetration through obstacles, making it perfect for rural areas and challenging industrial sites. With a wide array of interfaces including Ethernet, RS232, RS485, and multiple configurable I/Os, the TRB256 offers versatile integration with both modern and legacy industrial equipment.

Advanced Security & Management

Security is paramount in industrial applications. The TRB256 comes loaded with advanced security features, including a pre-configured firewall, numerous VPN services (OpenVPN, IPsec, WireGuard, ZeroTier), and attack prevention mechanisms like DDOS and port scan prevention. Running on the RutOS (an OpenWrt based Linux OS), it offers extensive customization and is fully compatible with the Teltonika Remote Management System (RMS), allowing for easy monitoring and management of your entire fleet of devices.

A little smaller than expected, but my puppy loves it! We've only had it for a few days, but it seems like it will hold up well.

Not for Destructive Dogs
Color: Blue
It might be okay for a little dog, but my heeler had it dismantled in short order and I threw it away. Cute toy, but not for a destructive dog.

So cute!
Good size toy, but my 1yr old Jack Russell is NB match for it. It’s good quality and I’m sure it would last longer with a less aggressive chewer.

Dog loves it! Squeaky on both ends!
Bungee rope is not as resistant as I wished, but its fun nonetheless! Squeaks in head and tail. Misssteped the tail and broke one squeaker, still fun though! Toy can handle a beating. Really happy with it!
