Tbox LT2 RTU | Remote Telemetry Unit

Benefits

The all-in-one Internet-ready remote telemetry unit for automation and monitoring applications offers outstanding functionality from a single compact, rugged unit.

Reduce installation costs compared with a SCADA or PLC network
Save engineering time without the need for complex programming
Real-time access to your data on the move through a standard web browser
Machine-to-Machine cellular connections
Reduce asset downtime through speedier response
Lower maintenance costs

Web server technology

The all-in-one TBox LT2 remote telemetry unit with 3G, 4G or LTE modem options provides real-time remote access and control of your assets, using the latest web server technology. On-board web server technology eliminates the need for complex SCADA software and costly HMI displays.

Programming

Servelec’s programming and dynamic analytical tools and libraries significantly reduce development time even for complex multitasking automation requirements. With TWinSoft, an easy-to-use and intuitive configuration tool users can quickly complete their applications and dynamically control communication, alarms, data logging and logic, locally or remotely, in complete security. TWinSoft also includes WebForm Studio which allows users to create dynamic embedded web pages without any coding knowledge.

Alarm management

TBox RTUs use push communications to send multimedia messages to defined groups and devices using escalation and shift management protocols and actions taken are recorded on the TBox’s local memory. At a specific time or following a change of state, a TBox RTU can automatically send messages to multiple recipients with attachments such as complete mobile-friendly reports with live and historical information, alarms and event notifications. Like email, SMS messages can be transmitted to multiple recipients at a scheduled time or following an event.

Security

All TBox devices and connected assets are protected by a state-of-the-art cyber security suite with authentication, encryption, firewall, SSL/TLS, HTTPS, SMTPS SFTP/FTPS and VPN.

Applications

Thousands of TBox LT2 units are in operation across the globe controlling building systems at world-renowned landmarks, monitoring broadcast transmissions to millions of people and monitoring supply levels of essential commodities such as oil, gas and water.
