One Device. Every Remote Site. Complete Control.

---

Managing remote assets across a distributed operation means dealing with a familiar set of problems: sites that are hard to reach, systems that don't talk to each other, aging hardware that's becoming impossible to support, and security vulnerabilities that keep your IT team up at night.

The Ovarro TBox was purpose-built to solve all of it — in a single, ruggedized package.

With over 350,000 installations worldwide across water and wastewater, oil and gas, and other critical infrastructure applications, TBox combines RTU automation, alarm management, data logging, built-in web server, and industrial-grade cybersecurity in one device. No additional gateways. No OPC servers to license. No separate alarming system to maintain. Just one platform that does the work of several — at a fraction of the total cost.

Operators who switch to TBox typically see cost savings of up to 50% compared to traditional PLC-plus-SCADA-plus-communications architectures.

Built for the Demands of Critical Infrastructure

Whether you're monitoring an elevated storage tank with 8 I/O points or managing a complex facility with hundreds, TBox scales to fit — and it arrives with the functionality you need already built in:

• Cybersecurity by default — every TBox ships with a full security suite including authentication, encryption, SSL/TLS, HTTPS, VPN, and firewall. Your assets are protected out of the box, not as an afterthought.
• Data logging on the device — log up to 32 GB of historical, event, and alarm data directly on the RTU. Schedule automated reports or push them to historians, databases, CSV/XLS files, or FTP destinations — no cloud dependency required.
• Alarm management and notification — define alarm groups, severities, and audit trails on the device. Push real-time notifications via email or SMS the moment something goes wrong, even at your most remote sites.
• Built-in HMI and web server — don't have a full SCADA system at every site? TBox includes a built-in web server that gives operators and technicians browser-based access to a "mini-SCADA" interface from any device, anywhere.
• Open protocol connectivity — native OPC-UA and MQTT support means TBox connects directly to your existing SCADA, cloud platforms, and MES systems. Modbus, DNP3, EtherNet/IP, IEC 60870-5, Fisher ROC, and more are included — no extra gateway hardware needed.
• IEC 61131-3 programming — configure automation logic using familiar Ladder Diagram, Structured Text, or Function Blocks. Rapid configuration means faster deployment and lower engineering costs on every project.

The Right Size for Every Application

TBox isn't one product — it's a family of solutions sized for the full range of remote site applications:

TBox MS — Modular System The scalable workhorse for larger or more complex installations. Configurable I/O and communications cards let it grow from small 5-point systems to hundreds of I/O per rack. The right choice when your remote sites vary significantly in size and complexity.

TBox LT2 — All-in-One The self-contained solution for standard remote site deployments. Up to 24 I/O points, integrated Ethernet and wireless communications, alarm notification, data logging, and web server — in a single compact unit ready for DIN-rail mounting.

TBox TG2 — Gateway / Edge Device All the power of the LT2, without physical I/O. The ideal solution for protocol translation, data concentration, IoT edge processing, or as a bolt-on alarming and logging layer for your existing control system.

TBox RM2 — Remote I/O Expansion Compact I/O expansion for TBox MS or LT2 systems — or any controller speaking Modbus. Connect additional field devices without replacing your existing architecture.

TConnect — Secure Remote Access Simplifies remote access to any TBox device over cellular without requiring a fixed IP address or managing a VPN network. Essential for operations teams managing assets across large geographic territories.

TWinSoft — Configuration Software An intuitive Windows-style configuration environment with wizards, predefined variables, and WebForm Studio for building embedded web interfaces — no coding required. And NO ANNUAL FEES!
