Product Description:

The VCP20.1BUN-768DN-NN-PW operator terminal belongs to the VCP IndraControl Terminals series from Bosch Rexroth Indramat. Intended as a compact human-machine interface, the unit combines an alphanumeric keypad with a graphic LCD to let users adjust parameters, monitor operating conditions, and issue commands to a PLC or drive controller. DeviceNet connectivity links the panel directly into the fieldbus layer, allowing data exchange with I/O nodes and motion controllers without additional gateways. By integrating power-supply conditioning and enclosure sealing, the terminal can be mounted on machine doors or control cabinets in general industrial automation cells.

Computation is handled by a Z84 microprocessor clocked at 10 MHz, which is sufficient for menu navigation and cyclic fieldbus polling. Program storage and user runtime files reside in 768 KByte Flash, while variable data and buffers occupy 128 KByte Static CMOS-RAM, and a backup source preserves retained values during power interruptions. The panel draws its logic power from a 24 V DC supply, and the internal regulator tolerates input swings between 19.2 V and 30.2 V without functional loss. When the backlight starts or multiple LEDs illuminate, inrush stays below the 3.0 A peak allowed for the control circuit. A membrane keyboard provides tactile feedback across 34 keys, giving direct access to numeric entry, soft functions, and system commands.

Visual feedback is delivered by an LCD module with a cold-cathode fluorescent tube backlight; the active area measures 131 × 72 mm and renders graphics at 240 x 128 pixels. Text and icons remain legible over a 90° reading angle, which supports overhead or side mounting positions without making the display difficult to view. The molded front bezel carries a sealed foil so the assembled face achieves IP54 protection against dust deposits and water splashes, while the rear side is rated IP20 for cabinet interiors.
