Product Description:
The APCBB33 is an industrial PC unit produced by B & R Automation as part of the APC Industrial Automation PC Units series. Intended to function as the primary controller in automated machinery, it executes real-time control algorithms, coordinates field devices, and generates operator interface data. By placing high-performance computing capabilities directly on the machine, the product reduces latency between program logic and drive, I/O, or safety hardware, supporting predictable cycle times required in modern production lines.
Its electrical interfaces are extensive. The controller offers 5 USB ports for service panels or data-logging devices and two standard RS232/RS485 COM ports for serial protocols. Network traffic is handled by 2 Ethernet ports that negotiate at 10/100/1000 Mbit/s, enabling simultaneous machine and enterprise communication. Visual output is routed through a female DVI-I connector, and storage media can be inserted in the two CompactFlash slots that accept Type I cards for recipe data or archived application files. A single add-on interface slot allows fieldbus expansion while keeping the housing compact. All signal lines benefit from galvanic isolation to break ground loops. The unit draws a nominal 24 VDC ±25% supply and requires 6 A during steady-state operation.
Internally, the APCBB33 carries 512 kB of fast SRAM for cyclic variables and an additional bank that preserves 192 kB of remanent data so machine counters or quality metrics remain valid after a restart. A battery-backed real-time clock keeps timestamps accurate during power removal, and the integrated buffer sustains logic operation for 10 ms to finish the current cycle before shutdown. Surge protection adheres to overvoltage category II, matching distribution networks inside control cabinets. The remanent memory and buffered shutdown function help preserve operating data during short supply interruptions and reduce the risk of incomplete cycle processing.
