Externally-powered RTU EVO datalogger for M-Bus and wM-Bus 868 MHz meters. For automatic, periodical reading of devices connected by cable (without dedicated M-Bus level converter, up to a maximum of 20 devices). wM-Bus connection requires a radio level converter. The data can be read locally or transmitted remotely.
RTUEVO1T (1.ETRSEQ.0051) is a datalogger for the acquisition of data from 1.ETRSEQ.0012 repeaters that collect information from wired and wireless MBus compliant devices, such as meters, cost allocators and sensors, via a MESH network. The device can handle up to 3000 meters (2500 wireless + 500 wired) and can store daily readings for 10 years. Its web interface allows you to display data, generate reports, and setup M-Bus and MESH networks.
It is also equipped with a graphic display panel for setup, viewing real-time data, and checking the status of onboard I/Os without requiring a PC. Up to 20 M-Bus* meters can be connected to the datalogger directly. It can be extended using up to 23 smart repeaters, each connected to up to 500 wireless devices. The M-Bus network can be extended with up to 6 level converters (1.ETRSEQ.0006, 1.ETRSEQ.0003). For easier installation, the package includes a remote antenna with 1.5 metres of cable.
Supports up to 3 user profiles: User, Maintainer, Administrator. Check the power supply based on the required type of installation.
The graphic display helps you to commission the measurement system in just a few steps. The main settings can be configured locally using the device display or using the web interface.
Using Internet, the device checks for updates and prompts the user to install them by a single click on the web interface.
The user can start scanning the M-Bus network to acquire the wired or wireless connected devices by pressing a single button. With automatic recognition of detected devices, you can start capturing data immediately, and generate automatic reports based on customisable preconfigured data sets, including unit of measurement, value type, description (language), thus eliminating the need of further user activity.
The device authenticates to the web site and the associated web server using the secure HTTPS protocol for additional protection against man-in-the-middle attacks. It also uses two-way client/server communication encryption for protection against contents interception, tampering and spoofing.
