MODBUS Gateway for EMH LZQJ-XC meters with two-wire MODBUS RTU RS485 connection

LKM series from IEC62056-21 to Modbus RTU. Protocol gateways are designed for use with electricity meters that communicate in the IEC62056-21 standard. Meters that support the IEC62056-21 standard have read tables that contain various data such as import energy, export energy, phase voltages and
currents. The LKM series Modbus RTU to IEC62056-21 protocol gateway automatically reads these values and maps them to Modbus registers. Field devices or software systems can easily read data over the Modbus RTU protocol so that energy meter readings can be easily integrated into field automation or monitoring systems without the need to implement the IEC62056-21 protocol.
LKM614 is specially designed for EMH LZQJ-XC and is a direct replacement for Variomod XC modules

## Technical features

- Plug and play designed for EMH LXQJ-XC meters
- Direct replacement for Variomod XC modules for EMH meters
- Automatically reads values in EMH meters and converts them into a predefined MODBUS register table
- Modbus address configurable via Modbus commands
- Reading period configurable on the IEC6056-21 side via Modbus commands
- Reading table number configurable on the IEC6056-21 side via Modbus commands
- Receives power directly from the meter
- Serial interface directly connected to the meter (with 15kV ESD protection)
- Wide operating temperature range from -40 to 85 °C
- Customization of the reading process and register tables based on customer request
- Firmware updatable over serial line
