Product Description:

The handheld operator pendant VCH08.1EAB-064ET-A1D-064-GS-B1-PW is produced by Bosch Rexroth Indramat within the VCH IndraControl Terminals series. It serves as a mobile human-machine interface that lets the operator issue motion commands and safety acknowledgments directly at the machine. This reduces trips back to a fixed cabinet HMI and supports faster response during setup and fault recovery.

The pendant presents information on a 3.8 in TFT that renders at 320 x 240 px, giving clear status icons and axis positions without occupying excess front-panel area. An Intel PXA270 416 MHz processor works with 64 MB of RAM to run the embedded control software, while a separate 64 MB flash device stores the operating system and screen layouts. The electronics draw no more than 4.8 W, so internal heat remains low during operation. All circuits are supplied from a single 24 VDC source that is typically provided by the machine control cabinet. The IP65 enclosure helps protect the unit from dust and water jets, and a USB client port allows program downloads or log retrieval without opening the housing.

Connection to the controller is established through a 8 m Ethernet cable that uses a bayonet lock to help prevent accidental disconnection. The internal network interface terminates in a RJ45 10/100Base-T port for standard switched Ethernet segments. Safety functions include a dual-channel emergency-stop button with a 2-Circuit design and two three-stage enabling switches with dual circuitry for redundant validation of the operator's grip. A mechanical handwheel and an override potentiometer provide fine motion control, while the membrane keypad offers 40 programmable keys for function assignments. These controls support manual jogging, speed override, and safe stop actions at the point of operation.
