Product Description:

The VCH08.1EAB-064ET-A1D-064-FS-B2-PW terminal is manufactured by Bosch Rexroth Indramat and belongs to the VCH IndraControl Terminals series. The model serves as an operator interface with a small backlit graphics display, multiple keys, an emergency stop, and enabling switches. This layout lets operators enter commands, view machine status, and carry out local safety actions directly at the machine. Its pendant-style construction places routine machine interaction and essential safety controls in one unit, reducing the need to move back to a fixed panel during operation.

In operation, the STN backlit LCD has a native resolution of 320 x 240 px. This QVGA format matches the compact viewing diagonal of 3.8 in, allowing status text and simple graphics to remain readable at arm’s length. An Intel PXA 270 running at 416 MHz drives the user interface and handles fieldbus communication without a separate controller. Application code and the operating system are stored in 64 MB of flash, and 64 MB SDRAM is available for variables and frame buffering. Forty sealed foil keys, including eighteen user-configurable function keys, provide direct access to machine commands instead of relying only on on-screen menus. The red-and-yellow emergency stop uses two circuits, and the pair of enabling switches uses three stages for typical safeguarded motion tasks.

Field connectivity is provided through an RJ45 10/100 BASE-T port that is prewired to a 0.5 m Ethernet cable with a bayonet lock, so the housing remains sealed to IP65. The terminal draws its logic supply from a control cabinet with a nominal bus voltage of 24 V DC, and even with the backlight active its power demand does not exceed 4.8 W. That low electrical demand helps limit heat inside the enclosure during operation. At 1.1 kg, the unit can be mounted on a light support arm without requiring counterbalancing, and the modest weight also helps when the terminal is carried during machine access.
