## Summary description

Single-phase electricity meter electro base ProBase™ MODBUS RTU 1F-1DIN-LCD is a DIN-rail mounted meter with an LCD for local reading and MODBUS RTU communication for remote data collection. Designed to measure single-phase consumption in residential or commercial installations, it supports integration into building automation and energy monitoring systems, enabling accurate billing, usage tracking and remote monitoring.

## Long description

Single-phase Electricity Meter electro base ProBase™ MODBUS RTU 1F-1DIN-LCD for DIN-rail with LCD display is a compact DIN-rail mounted meter for measuring single-phase electrical energy consumption. It combines a clear local LCD readout with MODBUS RTU communication for integration into building automation and energy monitoring systems. The meter records active energy and provides real-time voltage, current and power readings suitable for residential and small commercial installations where precise consumption tracking and remote data collection are required.
Advantages
The meter offers local visualization via a multi-segment LCD and reliable MODBUS RTU over RS-485 for remote polling. Its DIN-rail form factor allows straightforward installation in standard distribution boards. Designed for single-phase circuits, the device delivers accurate active energy measurement with stable performance under typical household and light commercial electrical conditions, supporting long-term monitoring and simplified billing workflows.
Suitable for
Monitoring single-phase household electricity consumption
Energy monitoring in small offices or retail premises
Integration into building management systems using MODBUS RTU
Sub-metering for tenant billing and cost allocation
Key specifications
Measurement type: single-phase active energy (kWh)
Display: built-in LCD for local readings of energy, voltage, current and power
Communication: MODBUS RTU over RS-485 for remote data collection
Mounting: DIN-rail (1 DIN module width)
Typical accuracy class: suitable for billing-grade or class-consistent metering (refer to official datasheet for exact class)
Operating environment: intended for indoor installation within electrical distribution panels
How to use
Install the meter on a standard DIN-rail inside the distribution board and connect line and neutral conductors according to the wiring diagram. Connect the RS-485 MODBUS RTU pair and set the device address, baud rate and parity to match the collecting system. Use the front LCD to verify voltage, current and accumulated energy readings during commissioning. For billing or monitoring, configure the SCADA, BMS or energy gateway to poll the meter periodically and store or visualise recorded values.
Usage recommendations
Ensure correct wiring and protective devices are in place before powering the meter; verify communication parameters and secure RS-485 terminations for stable MODBUS RTU operation. For accurate billing and long-term reliability, follow installation torque specifications and environmental limits from the manufacturer’s technical documentation.
