Peripheral remote terminal unit
Tesmec new RTU solution is specifically designed for remote control of secondary MV/LV substations.
The device TC-UPL20, is based on a modular architecture and it is fully configurable t meet the automation and control requirements, such as protocol handling for communication with the Control Center, field data acquisition and storage, FPI and fault detectors management, switch disconnectors’ and CBs’ control, and more.
TC-UPL20 implements the several protocols: IEC 61850, TCP/IP Modbus, IEC 60870-5-101 and IEC 60870-5-104, MQTT, DBR-DSR automation.
The device provides all the latest cybersecurity features, including HTTPS web server, encrypted communications, centralized secure authentication through RADIUS protocol, role-based access control.
- Communication to control center via IEC-60870-5-101 or IEC 60870-5-104 protocol
- IEC 61850 Client
- IoT sensors interface via MQTT protocol
- Local I/O acquisition and automation
- Cyber Security
