Product Description:
The VCP20.1BUN-768IB-NN-PW is an operator terminal built by Bosch Rexroth Indramat for the VCP IndraControl Terminals series. As a compact HMI panel, it provides local visualization and keypad entry so that PLC-controlled machines can be adjusted and monitored directly on the production floor. The unit integrates processor, memory, networking, and display components to serve as a decentralized control interface in industrial automation systems. Its integrated layout also allows the display and input functions to remain close to the process without requiring a separate external interface device.
The terminal’s processing core is a Z84 microcontroller that runs at 10 MHz, which is adequate for deterministic menu navigation and field data refresh. User logic, text, and graphic objects are stored in 768 kB of application memory, while volatile buffers are held in 128 kB of RAM to support temporary edits and screen updates during operation. Data exchange with the higher-level controller occurs over the INTERBUS fieldbus, so status bits and numeric values are transferred in a fixed-length telegram. Peak current during backlight start-up can reach 3.0 A, yet in steady state the electronics draw 0.4 A. The input accepts 19.2 V to 30.2 V around the nominal 24 V DC rail, which helps the terminal stay active during normal supply variation. This arrangement supports consistent transfer of operating states, alarms, and entered values between the panel and the connected controller.
The visualization surface measures 131 × 72 mm and is rendered at 240 × 128 px, giving sufficient pixel density for alarm banners, text pages, and simple bar graphs. The screen is an LCD with a CCFL backlight, which helps maintain readability in dim factory aisles and enclosed machine areas. Operators interact through 34 tactile membrane keys that include function, numeric, and navigation rows, allowing direct entry without an external pointing device. The front bezel carries an IP54 rating against dust and splash, whereas the rear housing meets IP20 for cabinet installation. This front-to-rear protection split suits door-mounted use, where the display faces the work area and the rear remains inside an enclosure.
