MR006DL M-Bus data logger for 20 devices with keypad and 2×16 LCD, RS232C

MR006DL – M-Bus data logger for 20 meters with keypad, 2×16 LCD and RS232C.

MR006DL is an independent M-Bus data logger with an integrated keypad and backlit 2×16 LCD, designed for central readout of up to 20 M-Bus devices (20 unit loads). It combines convenient on-site operation with a RS232C - M-Bus level converter function and automatic storage of readings, making it a practical choice for utility billing and consumption monitoring where you need data archiving without a permanently connected PC.

Local readout and on-site data view (keypad + LCD)

MR006DL supports local readout and quick value checks directly on the device, without a laptop. Using the keypad you can select a meter from the list, while key data is shown on the clear 2×16 LCD. This streamlines commissioning, routine inspections and fast on-site verification of the installation.

Automatic logging for 20 M-Bus devices

The core function of MR006DL is periodic M-Bus readout and storage in the unit’s internal memory. This allows you to build a consumption history for a larger number of meters without continuous PC connectivity. Logging and readout schedules can be managed via the device settings and supported through RS232C access when needed.

RS232C: PC / MODEM ports (DB9) and system integration

MR006DL provides an RS232C interface via two DB9 connectors: one for PC and one for MODEM. Only one connector can be active at a time. When inactive, the unit can operate as a transparent level converter, allowing an external system to use it as the physical M-Bus layer for communication with meters.

Stable M-Bus operation and protections

MR006DL is designed for networks up to 20 unit loads, providing stable communication and M-Bus line protection. Local diagnostics and on-device operation help service teams react quickly in sites where continuity of logging and fast fault isolation are important.

DIN rail mounting and power supply

MR006DL is intended for DIN rail mounting in control cabinets or meter rooms. Power input supports a wide range: 10..28 VDC or 13..28 VAC. The housing is rated IP20, which fits typical indoor installation environments.

MR006DL is a compact M-Bus data logger for up to 20 meters that combines local readout (keypad + 2×16 LCD), automatic logging and RS232C connectivity for PC/modem access. It is a practical solution for installations that require archiving, central readout and convenient service access.
