Product description

Remote reading. Single-phase. RS-485 port + Modbus RTU.
LE-01M is a static (electronic) indicator calibrated electricity single-phase alternating current in the system directly. It is used for readings and recordings taken of electrical energy for remote reading through a wired RS-485.

MID Directive 2004/22/EC
EN 50470-1/3



LE-01M under the influence of current flow and applied voltage makes precise measurement of the amount of consumed electricity. Energy consumption is indicated by a flashing LED (1600 pulse / kWh) and its value is determined by the LCD display. Decimals represent hundredths of kWh (0.01 kWh = 10 Wh).
Communication with the rate of working as slave devices is carried out according to the standard Modbus RTU via RS-485. Read register values after conversion kWh give a result consistent with the indications on the display indicator. Each of the indicators is identified by a unique address transmitted by the user.



The indicator has a pulse output SO+ - SO-. This allows you to connect another device pulse-reading (SO) pulses generated by the counter. For proper operation of the meter is not required to connect additional devices. 


Service program

Programs for remote reading of electricity meters
LE-01M, LE-01MP, LE-01MQ, LE-03M, LE-03MP, LE-03M CT


The MeternetPRO application allows remote reading of states and indications of counters, multimeters, measuring transducers, expansion modules of input/output and other measuring devices communicating through Modbus RTU protocol. The exchange of data between devices and the application is executed through RS-485 or local area network (LAN). The application, along with the database is installed on a special MT-CPU-1 server, which operates in a local network. Software user interface is a web application (web site). Access to the application is executed through any web browser. In a LAN with a public IP address, you can configure the application and read the data over the Internet.


Subscription billing of electricity consumption module
Module of the subscription billing of the power consumption or other recorded incremental value, for example: water, heat, etc. It allows you to calculate the increases in the value in the designated billing periods (intervals). Cycles: monthly, weekly, daily, hourly. The module allows you to create multiple individual and parallel reports.



Program allows remote reading via RS-485 network display up to 1000 indicators.
Exchange of data between the counters and the application is done via a standard RS485 <-> USB port or server on the LAN (Ethernet). For LAN connection to the router with a static IP address, you can read the data via the Internet.
