Wireless M-Bus modem
Wireless M-Bus AMR (Automatic Meter Reading) plug-and-play modems automatically collect energy data from water and gas meters.
100% compatible with the Wireless M-Bus standard (EN13757-3 and EN13757-4), device open protocols ensure full interoperability with other Wireless M-Bus products on the market.
ARF868 radio modem
ARF868 radio modems convert data from a serial link into a radio frame to send to a similar device in the frequency range 863- 870 MHz. The power and sensitivity allow the data to be transmitted over distances of up to 20 km.

Several types of communication

• RS232, RS485 or USB serial port.

With DIRIS G communication gateways, all information from metering and measurement devices communicating wirelessly or via the RS485 bus are centralised in a single device and then made available on the Ethernet network via Modbus TCP.
The gateway has an embedded WEBVIEW web server, allowing real time monitoring of electrical values and analysis of consumption data.The user can be alerted of any alarms via email.

Advantages WEBVIEW embedded web server

DIRIS G gateways include an embedded web server. Two versions are available:
• Power Monitoring:
- real time measurements and alarms
• Power & Energy Monitoring:
- real time measurements and alarms,
- Historical of measurements and analysis of consumptions.
• DIRIS D-90 touch-screen tablet can be fitted on the panel door to display WEBVIEW data.

Plug & Play

Connected metering and measurement devices are automatically addressed and detected by the DIRIS G gateway. DIRIS G gateways provide:
• Automatic clock synchronisation (SNTP).
• Synchronisation of connected devices.
• Warning messages in case of alarms (e-mail SMTP).
• Automatic recording and storage of measurements and consumption data.

Scalable

Several optional modules are available:
• Digital inputs/outputs
• Analogue inputs/outputs
• Temperature inputs
