Product Description:

The 2BP200.4 base plate is produced by B & R Automation for the System 2010 Controllers series. Within an industrial control cabinet, this carrier provides the mechanical and electrical interface required to attach a single I/O module, directing field wiring toward the controller’s internal buses without adding active circuitry. By fixing the relative position of adjacent modules and reserving clearance for service loops, the plate supports orderly installation, minimizes crosstalk between channels, and maintains the standardized footprint expected across the series.

The model is classified as a Main Base Plate, indicating that it occupies the primary position on the rail and anchors any expansion elements that follow. Signal transfer to the attached electronics occurs over the embedded I/O Bus, and no separate system bus runs across this plate. Dimensional constraints are tight, with a depth of 20 mm, a height of 285 mm, and a width of 40 mm, so panel space is conserved while still leaving room for field connectors, wire ducts, and ventilation gaps. These physical limits also support enclosure sizing and predictable airflow paths when plates are stacked in high-density control enclosures.

The plate is identified as a Base Plate Module and offers exactly 1 slot, so only one functional card can be mounted at this location. That slot accepts a single 1 I/O Module, simplifying small-system layouts because additional carriers are unnecessary. There is no bus termination on the plate, so an external terminator must be placed at the end of the rail whenever the I/O bus chain concludes with this unit. A separate system-level backplane is not present, preventing inadvertent connections to incompatible high-speed buses and keeping the wiring scheme limited to the local I/O segment.
