Universal gateway of the A series

maxi | Mk II | PROFIBUS

Small-format performer for sophisticated building automation

Anyone who operates a large property needs a lot of space to set up the corresponding infrastructure. So it's good if individual technical elements of an automation system don't take up too much space. With the maxi | Mk II | PROFIBUS, MBS is now providing a communication interface with impressive features in the form of a new development in the proven "maxi" gateway series: With the smallest dimensions and a maximum of 40,000 data points, it is currently the most space-saving and at the same time most powerful gateway on the market.

The communication infrastructures of extensive properties present their operators with major challenges. If, for example, the fire alarm system alone comprises a six-figure number of smoke detectors with perhaps three data points each, the necessary equipment at automation level requires a lot of space. Entire batteries of control cabinets were previously required just for the installation of the gateways, which serve as the communication interface for the various communication protocols. And then there is the associated cabling and power consumption.

Fast integration

The integrated PROFIBUS adapter eliminates the need for the usual external bus coupler and reduces the amount of cabling required. This also enables faster connection to serial and network-based communication protocols.

High performance with low volume

The Gateway maxi | Mk II | PROFIBUS provides relief here. The tried-and-tested hardware component from MBS GmbH has been completely redeveloped. The result is extremely handy and powerful: it is only a third of the size of conventional devices and its smaller volume alone significantly reduces the number of control cabinets required. As if that wasn't enough, MBS has also doubled the number of data points - the basic version now has 20,000 data points and the extended version 40,000. This reduces the number of components required enormously.

Ultimately, not only are fewer hardware components and less space required in the control cabinet, but the cost of cabling and electricity is also significantly reduced. This means cost savings not only in terms of procurement, but also in terms of control cabinet installation and system operation. There is currently no other gateway on the market that can keep up with these dimensions and this number of data points.

Modular design for flexible applications

The Gateway maxi | Mk II | PROFIBUS can be easily integrated into existing building automation systems. It has a modular design so that the bus-specific add-on boards, which have already proven themselves in the other series, can be installed directly in the device. In addition to the standard bus protocols, such as KNX, CAN, LON etc., manufacturer-specific communication protocols can also be added on request. The product is also available as OEM hardware.

Users who are already familiar with the gateways from MBS GmbH will be pleased that the firmware that has been tried and tested over many years is also used for the new development - so they do not have to familiarize themselves with new software. In addition, bugs that can occur in new firmware are practically ruled out.

Familiar quality, impressive performance

All MBS products have two things in common: firstly, feedback from partners and customers is incorporated into their development. Secondly, they are put through their paces before being launched on the market. The Gateway maxi | Mk II | PROFIBUS has already been in use in an industrial environment for six months and has passed this field test with flying colors. With its hard-wearing metal housing, it stands out from the plastic boxes that are otherwise often used, especially in robust control cabinet environments. 

The new development replaces its predecessor model and the 19'' gateway. Users who want to add more devices to existing ones can easily integrate the new communication interface into their system. This is because it fits seamlessly into the product range: Nothing changes in terms of handling and firmware, while the quality of the new maxi | Mk II | PROFIBUS gateway is at the same high level as usual at MBS. At the same time, with a lower volume and a maximum of 40,000 data points, it is far ahead in terms of performance. A 19'' variant, optionally with redundant power supply units, is available if required.
