Product Description:
The VCP20.1BUN-256RS-NN-PW is an operator terminal produced by Bosch Rexroth Indramat within the VCP IndraControl Terminals series. Deployed on machine fronts or control cabinets, the unit serves as a compact human-machine interface that lets operators issue commands and monitor process status through its membrane keypad and graphic display. In an automation line, it passes field data to the PLC and presents diagnostic feedback directly at the machine, reducing reliance on centrally located workstations.
The terminal is energized from a regulated 24 V DC source and draws 0.4 A during steady operation, which helps keep panel power supplies compact. A Z84 CPU running at 10 MHz executes the visualization firmware, while 128 kB of static CMOS RAM holds variables that must be updated on every scan. Application programs reside in 256 kB of Flash so configuration files are retained when the unit is powered down. Operator feedback appears on an LCD module with a cold-cathode fluorescent backlight, and its graphics engine addresses a raster of 240 × 128 pixels to show alarms, trends, or bitmaps with moderate detail. The tactile keypad provides 34 keys that can be assigned to machine functions, numeric entry, or navigation.
The enclosure has a rating of IP54 Front / IP20 Rear, allowing installation in areas exposed to dust or occasional splashes while still permitting convection cooling inside the cabinet. Screen legibility is supported by a 131 × 72 mm viewing area and a 90° reading angle so operators can read status information while standing close to the machine. Serial data exchange occurs over RS232/485, TTY 20 mA links, letting the terminal communicate with legacy drives or modern PLC ports without protocol converters. During startup, the inrush current reaches a peak of 3.0 A, which is useful for fuse sizing. Mechanical integration is straightforward because the aluminum bezel measures 160 × 300 × 3 mm and fits into a 152 × 196 mm cutout in the enclosure door.
