LKM114: MODBUS RTU to IEC62056-21 Meter Gateway (RS485 MODBUS side, RS232 Meter side)

LKM series Modbus RTU to IEC62056-21 gateways are designed to be used with electricity meters communicating according to the IEC62056-21 standard. Meters supporting the IEC62056-21 standard have reading tables that contain various data such as import energy, export energy, phase voltages, and currents. The LKM series Modbus RTU to IEC62056-21 gateway automatically reads these values and maps them into Modbus registers. Field devices or software systems can easily read data via the Modbus RTU protocol, so that electricity meter reading can be easily integrated into field automation systems without the need to implement the IEC6056-21 protocol.

## Technical Features

- 2-wire RS485 connection on the modem side and Rx-Tx-GND RS232 connections on the meter side.
- Automatic reading of electricity meters communicating according to the IEC62056-21 standard and mapped into a predefined MODBUS register table.
- Modbus address configurable via Modbus commands
- Configurable reading period on the IEC6056-21 side via Modbus commands
- Configurable reading table number on the IEC6056-21 side via Modbus commands
- Wide range power input: 5V - 24V DC
- Wide operating temperature range from -40 to 85 °C
- Very small form factor, only 2.1 x 4.2 x 4.4 cm
- Customization of the reading process and register tables according to customer requirements
- Firmware upgradeable via serial line
