MR006 supports up to 20 M-Bus meters and simplifies the integration of small metering installations.
MR006 is a compact M-Bus master, also referred to as an M-Bus level converter, designed for the remote powering and reading of up to 20 M-Bus devices. This model was created as an economical and practical solution for small and medium-sized metering installations where stable communication, simple integration and low implementation cost are important. MR006 works very well for reading water meters, heat meters, electricity meters, gas meters, pulse meters, as well as analog and digital input modules.
Thanks to its compact design and straightforward architecture, MR006 is a very good choice wherever you need a reliable access point to the M-Bus line without using an oversized and expensive solution. This device is particularly suitable for billing installations, technical metering points, small utility monitoring systems and applications where meter data must be transferred to a PC or a supervisory system.
MR006 for small and medium-sized M-Bus installations
The biggest advantage of MR006 is its simplicity combined with functionality that is sufficient for many real-world projects. The device supports up to 20 standard M-Bus loads, which makes it very suitable for residential buildings, small commercial facilities, service premises and technical installations where the number of meters is not very high, but stable and centralized communication is still required.
In practice, MR006 allows you to build a simple remote utility reading system without unnecessarily complicating the entire infrastructure. This is especially important in applications where fast commissioning, easy service and predictable long-term operation are essential.
Integration with water, heat, electricity and gas meters
MR006 can work with many types of M-Bus devices used in utility metering systems. This includes water meters, heat meters, electricity meters, gas meters, pulse meters and analog or digital input modules. As a result, one compact master can become the central element of a small metering infrastructure.
For the integrator, this means easier deployment and simpler connection of the system to software used for billing, consumption analysis and technical monitoring of the facility. MR006 fits well into projects where meter data must be sent to PC software or to a higher-level building automation system.
RS232 interface and optional ZVEI optical reading
As standard, MR006 is equipped with an RS232 interface that enables communication with a PC or another supervisory system. This is a classic and proven solution for small M-Bus systems where ease of connection and smooth cooperation with meter reading software are important.
In addition, the MR006 IR version is available with an optical interface compliant with ZVEI. This option increases service convenience because it enables data reading using a handheld terminal or optical head without the need to maintain a permanent wired connection to a computer. It is particularly useful in installations where service is mobile or readouts are performed periodically.
Stable bus operation and overload protection
MR006 was designed as a reliable master for everyday operation in small and medium-sized M-Bus networks. The device is resistant to overloads and bus short circuits, which improves the safety of the whole installation and reduces the risk of downtime in the event of wiring faults or problems on the connected devices.
Operating status is indicated by LED indicators that show power, data transmission and alarm conditions. In practice, this type of diagnostics makes service work much easier because it allows the user to quickly assess whether the issue concerns communication, bus overload or device power supply.
DIN rail or wall mounting and flexible power supply
MR006 is designed for DIN rail TS35 mounting or wall mounting, which gives strong flexibility when designing a meter reading point. Thanks to its compact housing, the device can be easily installed in control cabinets, distribution boards, technical enclosures and local metering points.
Another important advantage is the wide AC and DC power supply range, which makes it easier to use existing power supplies already available in the facility. The ABS housing provides an IP20 protection rating, making this model well suited to standard indoor technical applications.
