Built for Reliable Remote Meter Reading
Reliable 4G Connectivity
LTE Cat.1/Cat.4 options, automatic link recovery, and built-in watchdog mechanisms help maintain reliable communication across distributed metering sites.
Multiple Metering Protocols
Supports IEC 62056-21 Mode C, DLMS/COSEM, and Modbus RTU for communication with a wide range of compatible meters.
Flexible Interfaces for Field Integration
Dual isolated RS485 ports and built-in digital I/O support diverse field connections, with Ethernet and relay outputs available as options.
Head-End System Integration
Supports MQTT/MQTTS, MASS, and TeleMetriX Head-End protocols for data communication with compatible meter data collection systems.
Event Detection & Remote Maintenance
Power failure and enclosure-opening detection help identify field issues, while remote firmware upgrades simplify ongoing maintenance.
工業グレード設計
Wide-range 55–270 VAC input, -30°C to 70°C operation, and Li-ion battery or supercapacitor options support deployment in demanding electrical environments.
