Products Description
A metering terminal block with the cellular module built in - it reads your meters over the mobile network and reports to the cloud, with no fixed-line broadband and no on-site meter reading.
It terminates CT/PT secondary wiring and meter circuits as any metering block does, while an integrated multi-band 2G/3G/4G module uploads interval data to your platform. The wireless data path suits sites where a communication cable is impractical: remote transformer districts, overseas AMI rollouts, solar plants and unmanned substations. A 30-day buffer protects the readings, and a built-in bypass allows meter testing or replacement without cutting the supply.
Technical Specifications
Values describe the configurable platform rather than a single fixed part. Confirm the communication bands for your market against the final datasheet before ordering.

Product Advantages
No fixed-line network needed. Multi-band cellular works wherever mobile coverage exists - no cable trench, no fibre lease.
Near real-time reporting. Upload intervals configurable down to 15 minutes, with a delivery rate above 99%.
No data loss when the network drops. Readings buffer locally for 30 days and forward automatically.
Remote switching control. Trip and close commands for load shedding and prepaid disconnect/reconnect.
Meter exchange without an outage. The built-in bypass lets a meter be swapped under load.
Protects the meter itself. ≤0.35 mΩ contact resistance limits thermal rise; ≥2.5 kV dielectric strength; IP65, -40 °C to +85 °C.
Speaks your platform's protocol. DL/T645, Modbus RTU and IEC 60870-5-104 integrate into SCADA and billing systems.
