Product Description:

The VCH08.1EAB-064ET-A1D-064-DS-E4-PW handheld terminal is produced by Bosch Rexroth Indramat as part of the VCH IndraControl Terminals series. It serves as a portable human-machine interface inside automated cells, giving direct access to motion commands, data entry, and emergency stop functionality at the point of operation. By integrating the display, keypad, and safety elements in one sealed unit, the device removes the need to stand next to a fixed cabinet when jogging axes or confirming process steps. It can be carried to different sides of a machine, which helps when controls need to stay close to the active work area.

All electronics are powered from a nominal supply of 24 V DC, and the internal circuitry draws only 4.8 W, which helps limit heat during continuous duty. Visual feedback is provided by an STN panel measuring 9.7 cm (3.8 in.) and offering a native resolution of 320 x 240 with five gray tones for simple status graphics. The unit includes 64 MB of application RAM and the same amount of flash storage, so interface pages and recipes remain available after power loss and updates can be transferred over the Ethernet lead. User input relies on 15 dedicated function keys, 40 general operating keys, and a single handwheel, allowing quick mode selection, alphanumeric entry, and fine incremental positioning without navigating nested menus.

The molded housing spans a diameter of 250 mm and is only 114 mm deep, giving the terminal a flat profile that rests securely when carried by the cable. A sealed membrane front and gasketed joints give the assembly a protection rating of IP65, so dust and low-pressure water jets will not compromise the electronics. For emergency shutdown, a prominent stop button uses a 2-circuit contact arrangement that opens two channels at the same time. This supports dual-channel safety architecture commonly used on industrial machinery.
