SCB211DL is a smart DLMS COSEM Meter Cellular Gateway with LTE or NBIoT network. The IP54 Fire Resistance ABS Enclosure can protect from dust, moisture, and rain from the outdoor environment. The RJ45 connector from Cable Gland connector includes one two-wire RS485 for DLMS Power Meter to read OBIS codes and 12V power input from the Power Meter. No extra power supply is required. To safeguard cybersecurity, security features such as Firewall, OpenVPN, GRE tunnel are supported. The embedded COAP protocol enables HES integration for Smart Meter System. The ThingsMaster OTA safeguards the device from the remote control center to detect and fix abnormalities at local sites.
