Product Description:

The VCH08.2EKB-064ET-A1D-064-ES-E3-PW is an operator terminal produced by Bosch Rexroth Indramat within the VCH IndraControl Terminals series. It functions as a human-machine interface that permits direct interaction with PLC-based control systems on factory lines, packaging machines, and material-handling cells. By integrating the display, processor, and network ports in a sealed housing, the unit simplifies panel layout and reduces cabinet wiring. Operators can view process data, acknowledge alarms, and enter commands directly at the machine.

The housing carries an IP65 enclosure rating, so the front surface resists dust ingress and low-pressure water jets found at washdown stations. For network connectivity, the terminal provides 1 x RJ45 supporting Ethernet signaling at 10/100 Base-T; this link moves process variables between the HMI and supervisory computers without additional fieldbuses. Computation and graphic rendering are handled by an Intel PXA 270/416 MHz processor that balances low power draw with adequate refresh rates for typical screen objects. Application code and operating system files reside in 64 MB of flash memory, allowing stored data to remain intact through power cycles. Runtime variables are buffered in SDRAM, which supports trend graphs and alarm lists without paging delays.

The terminal accepts a supply window of DC 19.2 V to DC 30 V, and this range lets it ride through dips that occur when large actuators start. At energization, the circuitry can draw up to 5.6 A of inrush current as capacitors charge, which must be considered when sizing circuit breaker curves. During steady operation, the electronics consume about 4.8 W, helping keep enclosure thermal rise minimal. Most installations feed the unit from a dedicated DC 24 V rail, so the terminal can share power distribution with sensors and I/O modules. This arrangement keeps control hardware organized and supports straightforward integration in compact panels.
