The M1 automation system is based on an ingenious and field-tested modular concept. Precisely matched to the respective requirements, automation engineers can assemble the technically and economically optimized configuration from a broad selection of modules. Extremely space-saving standardized module sizes, robust and absolutely maintenance-free mechanical design as well as immunity to external influences particularly characterise the M1 system concept from Bachmann electronic.

Power Supply Module NT255

With the NT255, Bachmann electronic sets new standards for the power supplies of CPUs and backplane-supplied modules. As a result of intensive development work and in consideration of field experiences with several thousand supply modules, the NT255 combines long term knowledge with the latest technologies.

Best possible, selected components and lifetime optimized design form the reliable base for the module. Recent planar transformer technologies ensure a significantly increased efficiency, the integrated heat dissipation in the circuit board (»coolPCB technology«) prevents even minimal local warming and thus the early ageing of components. Moreover, because of the extremely reduced weight of the parts, the module is even more robust against shock and vibrations.

In spite of the primary design focus on a long service life and robust design, the NT255 also offers outstanding technical features: up to 80 % longer buffer time at short voltage drops and generous power reserves (55 W peak power) for temporary overload ensure safety and reliability in every respect.

  • Input voltage range 18 to 34 VDC
  • Provides all the necessary CPU voltages as well as supply for modules on backplanes
  • 45 W output power (55 W peak power)
  • Galvanic isolation input /ground
  • Galvanic isolation input / system
  • Electronic reverse polarity protection
  • 2 state indicators allow differentiation between supply failures and internal errors
  • Monitored supply voltage
  • Monitored output voltages
  • Power-fail signal and state information for CPU module (processable from application)

Available accessories for NT255:

Dummy Module LM201

The dummy module LM201 is used as fill-in for later extensions and does not contain any electronic components. Used to protect the backplane.

  • Placeholder for one module slot
  • No electronics
  • Used to protect the backplane 

 

See specifications for item:

Backplanes BS200 Series

The backplanes BS201 to BS216 interconnect the M1 controller hardware modules, such as power supplies, CPU modules and input /output modules, mechanically and electrically. They are the backbone of the controller. The DIN rail adapters S201 and S202 are identical in construction, without electrical function and they are used for solitary modules.

  • 1 to 16 module slots
  • Seamless connection/ possible
  • Stabile mechanics / compact design
  • Vibration proof fixing of modules
  • Can be snapped on EN 60715 DIN rail

 

See specifications for item:

Backplanes BS200 CC Series

The backplanes for BS200/W CC for cold weather and protection class 1 interconnect the M1 controller hardware modules, such as power supplies, CPU modules and I/O modules, mechanically and electrically. They are the backbone of the controller.

  • 1 to 16 module slots
  • Seamless connection/ possible
  • Stabile mechanics / compact design
  • Vibration proof fixing of modules
  • Can be snapped on EN 60715 DIN rail
  • ColdClimate design (protected against temporary condensation)

 

See specifications for item:

Backplanes BS200/S Series

The backplanes of the series BS200/S for protection class 1 interconnect the M1 controller hardware modules, such as power supplies, CPU modules and input /output modules, mechanically and electrically. They are the backbone of the controller.

  • 3 to 16 module slots
  • Seamless connection/ possible
  • Stabile mechanics / compact design
  • Vibration proof fixing of modules
  • Can be snapped on EN 60715 DIN rail
  • For protection class 1
  • Grounding tab (item no. 00016115-00) for protective conductor connection, necessary for use of voltages other than SELV

 

See specifications for item:

Backplanes BS200/E Series

The backplanes BS200/E interconnect − as the BS200 series − the M1 controller hardware modules, such as power supplies, CPU modules and input / output modules, mechanically and electrically.

With its robust design, the E series ensures direct mounting on the control cabinet back panel without a DIN rail to optimize thermal and mechanical connection. Through this coupling, the heat can be transported through the rear panel of the cabinet housing, in which the cooling of the interior becomes much easier. Frequently, a maintenance-intensive active cooling of the components in the interior can therefore be avoided. A functional earth connection is prepared.

  • 3 to 10 module slots
  • Seamless connection / expandable
  • Stabile mechanics / compact design
  • Vibration proof fixing of modules
  • Directly mounting
