The backplane combines the node adapter and the I/O modules into a mechanically robust EMC compliant unit. Fully fitted I/O stations can thus be pretested after mounting and transferred to the application without further modification. Backplanes enable real-time communication between modules as well as with the node adapter and provide the power supply to the logic side of the modules.
Thanks to the M100’s IP40-compliant design and mounting concept, stations can be mounted directly on or in the machine, either on a DIN rail or with screw fixings. Individual modules are also screwed into place, remaining stable even under considerable vibration or impact loads.
Empty slots on backplanes are useful for optional retrofits, machine variants or for keeping reserve space in plant construction. The BPC101 backplane slot cover protects each slot from mechanical influences, electrostatic discharge and contamination.
