Product Description:
The 5C2001.21 compact processor is produced by B&R Automation within the 5C2 Compact Processors series. Designed as the central PLC-class computer for industrial automation cells, it executes user programs, delivers visualization data, and mediates fieldbus traffic from inside a control cabinet. A built-in coprocessor offloads peripheral tasks so deterministic cycle times remain stable during complex machine sequences.
Its computational base is a 486DX5-133 MHz CPU that handles time-critical logic, while an onboard 32 MB DRAM array stores the operating system, motion libraries, and process variables. Nonvolatile data and application files reside on a 2.1 GB IDE hard disk, giving sufficient space for recipes and historical logs. The controller is powered by a 24 V DC supply and typically draws only 18.8 W, which minimizes cabinet heat. A 1 MB graphics memory block driven by the C&T 65550 controller produces VGA signals for local HMI panels, while the Award Elite BIOS manages boot functions and peripheral identification. Continuous airflow from the integrated 40 mm ball-bearing fan keeps component temperatures within acceptable limits.
External communication is handled through an isolated CAN interface located on the COM3 plug, a BNC-based Ethernet interface that is NE2000 compatible, and four serial interfaces that support legacy devices such as barcode scanners or weight transmitters. Two Type II or one Type III PC Card slots accept flash disks or fieldbus adapters, and the bidirectional LPT1 port supports printer or parallel I/O modules. Mechanical integration is simplified by the unit’s 182 × 182 × 50 mm enclosure, allowing dense mounting on DIN rails or backplates. This layout lets the processor support local visualization and multiple communication links from one cabinet-mounted unit.
