The LM201 (Part Number: 00012220-00) is a blank filler module for the Bachmann M1 backplane, providing mechanical slot protection for unpopulated positions. While containing no electronics, it maintains structural integrity, dust protection, and optimal airflow, ensuring reliable operation of the PLC rack.
The LM201 allows for future expansion, enabling empty slots to later accept active I/O or communication modules without altering the physical layout of the backplane or DIN rail.

Used in Bachmann M1 backplanes (e.g., BS206, BS210) to fill unused slots, maintaining vibration stability, IP-rating compliance, and thermal management. Common in wind turbine control cabinets, maritime automation, and other industrial PLC racks.
Does the LM201 require a bus connection?
No. The LM201 is purely mechanical and does not connect to the system bus. It securely locks into the backplane using standard module fixing mechanisms.
