Product Description:

The VCP20.2DUN-003-SR-NN-PW operator terminal is manufactured by Bosch Rexroth Indramat as part of the VCP IndraControl Terminals series. It functions as a compact human-machine interface that presents process data, accepts operator commands, and links controllers and field devices in automated installations. Mounted on the front of a machine panel, the unit combines a graphical display, tactile keys, and integrated communication ports so PLC status, alarms, and setpoints can be viewed and adjusted directly at the machine. The front-mounted layout also allows routine navigation and alarm acknowledgment without opening the control cabinet.

The terminal uses a 5.7 in monochrome FSTN screen that renders five gray levels at a pixel matrix of 480 x 272. This resolution supports clear depiction of numeric values, bar graphs, and simple mimic diagrams used for line supervision. A RISC ARM9 200 MHz processor runs menu logic, alarm handling, and communication tasks while maintaining responsive screen updates. The device includes 3 MB of application memory for user pages and scripts, along with 16 MB of Flash for the operating system and project data. One Ethernet TCP/IP port, two USB host sockets, and a multiprotocol RS232/RS485 channel provide links to PLCs, drives, and external computers.

The aluminum front carries a sealing gasket that achieves IP65 ingress protection when the unit is fastened to a control cabinet, allowing use in washdown-prone packaging areas. The electronics run from a regulated 24 V DC supply and draw only 6 W, which helps limit panel heat and keeps demand low on auxiliary power circuits. The housing measures 160 mm high by 300 mm wide and has a mass of 1.3 kg, so it remains easy to mount in a standard panel cutout. The moderate weight also helps support a stable installation during frequent key actuation.
