Product Description:

The VCH08.1EKB-064ET-A1D-064-ES-E6-PW operator terminal is produced by Bosch Rexroth Indramat for the VCH IndraControl Terminals series. This panel-mount unit serves as a compact human-machine interface, allowing operators to enter commands and view process data in automated machinery. By combining push-button entry with a small graphical screen, the terminal connects controllers and field devices so that parameters can be monitored, adjusted, and acknowledged directly on the machine. Its circular layout suits installations where front-panel space is limited but direct local access is still required.

The housing is 55 mm deep and 250 mm in diameter, so it fits restricted mounting depth while still providing a circular key arrangement. The front panel integrates a 3.8 in diagonal display that uses STN technology. With a resolution of 320 x 240 px and support for five gray shades, the screen shows text, symbols, and simple process graphics for menus, status messages, and alarm lists. Operator input is handled through 40 membrane keys that can be assigned to numeric entry or machine functions. The terminal also includes 64 MB of SDRAM, while an equal amount of flash memory stores the operating system and application data. An Intel PXA-270 processor running at 416 MHz manages screen refresh and communication tasks without requiring a separate cooling fan.

Power is supplied at 24 VDC, and the unit typically draws 4.8 W, which lets it share low-voltage control circuits with sensors, relays, and similar devices. For mounting on machine frames, the enclosure has an IP65 rating that helps block dust ingress and low-pressure water jets. Network connectivity is provided through a RJ45 10/100 Base-T connector for Ethernet communication with PLCs and related control hardware. A USB client port supports file transfer and service access, and the nonvolatile flash memory retains settings when input power is removed. This allows the terminal to keep application data available after a power cycle.
