LKM616 868MHz LoRaWAN Meter Reader with MODBUS TCP to IEC62056-21 Meter Gateway for EMH LZQJ-XC Meters, Direct Connection to the Meter

- 1 x 10/100 Ethernet port
- Plug and play design for EMH LZQJ-XC meters; direct replacement for Variomod XC modules for EMH meters
- Serial interface directly connected to the meter (isolated, up to 5000 VRMS isolation rating, up to 10 kVPK surge capability, overload and short-circuit protection, thermal shutdown)
- Embedded web interface
- Reads the EMH LZQJ-XC meter with IEC 62056-21 (Mode C) or DLMS/COSEM
- Reads 1 meter; Modbus TCP function only: Serial Electricity Meter to Modbus TCP Gateway (and MQTT Publisher)
- Up to 48 OBIS codes per meter profile; only the IEC 62056-21 and Generic DLMS profiles (DLMS/COSEM meters are read with the Generic DLMS profile)
- Negative meter values keep their sign; a value too large for the 32-bit register gives a fixed limit value
- Modbus TCP server with up to 10 clients at the same time
- Function code 03 (Read Holding Registers); every value is 32 bits = 2 registers, 48 values per meter row
- MQTT publisher with two data formats (OBIS VALUES AS OBJECTS and OBIS VALUES AS MODBUS FRAME), at the same time as Modbus
- 868 MHz LoRaWAN Meter Reader: the meter data is also sent to a LoRaWAN network server through a LoRaWAN gateway
- Radio band EU 868 MHz (Europe); the send interval is set by the user
- Built-in duty cycle check and payload size check: the device splits the data by the maximum payload size and the duty cycle block times, so the meters can be read at any interval
- Activation over the air (OTAA) or by personalization (ABP); Class A or Class C
- Adaptive Data Rate, selectable uplink data rate and Tx power level (EIRP), user defined LoRaWAN port, with or without ACK
- Device and LoRaWAN status on the LoRa Status page, including the latest LoRaWAN messages
- Meter reading, Modbus communication and OBIS-to-Modbus mapping status, and the meter read-out data, on the web interface
- Device Status overview cards for the meters, Modbus, MQTT and LoRaWAN, each with a green, amber, red or grey dot
- White list or black list IP filter with up to 20 IP addresses (in the Modbus TCP function)
- DHCP server
- Firmware update over the web interface; 2 firmware banks in the device (1 active), the previous firmware can be started again
- Configuration backup and restore as a file
- No console connection for logs; the log goes to a UDP server
- Gets power directly from the meter (isolated, isolation voltage up to 1500 VDC)
- Operating temperature -40 to 85 C
- ABS housing, IP51, 105 x 45 x 27 mm (h x w x d)
