Product Description:
The 3BP152.41 controller base unit is produced by B & R Automation as part of the System 2005 Controllers series. In an automation cell, this hardware forms the physical backbone that joins the CPU, power supply, and I/O slices into a single rail, supplying internal bus power and communication paths between modules. By providing a rigid mounting frame and integrated signal routing, the product streamlines cabinet wiring and supports deterministic control cycles in factory machines. The base unit also keeps adjoining modules aligned so the control stack remains mechanically stable during operation.
The unit ships with an onboard backup battery that preserves configuration parameters during power loss. This support helps the controller retain essential operating data after an outage and keeps the real-time clock active while main power is absent. Its storage element is a button-cell rated at 950 mAh and delivers a nominal 3 V, giving several years of real-time clock support before replacement is required. Overall chassis depth is 23 mm, so the assembly fits shallow enclosures and allows dense horizontal mounting. Internally, the controller rail offers 9 logical slots, including a CPU position, integrated power distribution, and additional bays for field wiring adapters. Total front width reaches 360 mm, providing room for status indicators and keyed connectors without crowding adjacent hardware.
To extend process connections, the System 2005 design supports up to 7 I/O Modules on the expansion backplane; the same limit applies to the primary system backplane, which helps keep signal propagation times predictable. This arrangement provides room for local signal expansion without requiring a separate rack segment. Cabinet planning is further supported by the profile height of 165 mm, which aligns with standard DIN-rail clearances and still leaves the recommended side gap of 20 mm for airflow and service access. The plastic housing meets the IP20 protection class, so it is intended for clean, dry control cabinets where accidental contact with live parts is limited by the enclosure rather than by a sealed housing. Because the housing is open to the cabinet environment, installation areas should remain free of excessive dust and moisture.
