Product Description:
The 5C2000.03 processor unit is manufactured by B&R Automation as part of the 5C2 Compact Processors series. The module serves as the central CPU slice in machine-level controllers, providing deterministic cycle execution for sequencing, data handling, and field communication in industrial automation. Its compact design allows direct mounting in control cabinets and easy integration with I/O stacks, so it provides centralized control while remaining small enough for decentralized architectures.
Its computing core is the 80486SXLC2-50 microprocessor, paired with 4 MB of dynamic RAM that stores user programs and real-time variables. Nonvolatile data and operating system components reside on a 504 MB hard disk, giving adequate space for recipe files and event logs. The board draws logic power from a 24 VDC supply fed through the backplane, eliminating separate AC wiring. Field networking is possible through an electrically isolated CAN interface, which protects the CPU from ground shifts between distributed nodes. Two isolated serial ports provide electrical separation for service tools, and four serial interfaces with 16-byte FIFOs handle continuous data exchange without blocking the processor.
Removable media support includes a 3.5-inch, 1.44 MB diskette drive for system updates and log retrieval. Card expansion is available through 2 Type II PC-card slots that comply with PCMCIA 2.0 / JEIDA 4.1, allowing added flash storage or fieldbus adapters. Standard communication lines include one parallel port, a PS/2 AT keyboard interface, and serial formats selectable as RS232, RS232/TTY, RS485/TTY, or RS232/RS422. Two additional non-isolated serial channels share the same connector group. Cooling is provided by a temperature-controlled fan that engages only when internal sensors detect rising heat, and a battery-backed real-time clock keeps timestamps accurate during power loss.
