Product Description:

The VEP40.4APN-512NN-MAD-1G0-NN-FW is an operator terminal manufactured by Bosch Rexroth Indramat and assigned to the VEP Embedded Terminals series. This panel-mount unit serves as the human-machine interface in automated lines, providing on-screen status data and enabling command input directly at the machine. Its combined computing core, display, and touch sensor reduce cabinet depth and shorten signal paths between the controller and field devices, which streamlines installation in tight electrical enclosures. This arrangement also allows operators to view alarms, process values, and screen-based controls without relying on a separate nearby workstation.

The electronics are supplied with 24 V DC; this low-voltage input allows direct connection to common control power buses. Under continuous operation the terminal draws up to 1.5 A, translating to a ceiling power demand of 36 W, while the short-term inrush can reach 7 A during power-up, so upstream protection must tolerate that temporary surge. A Celeron M 600 MHz processor performs local graphics handling and data logging, assisted by 512 MB of RAM for runtime variables. A 1 GB CompactFlash card stores the operating system and application files, offering solid-state resilience against vibration. Because no integrated fieldbus interface is present, network access is handled through higher-level Ethernet or serial ports provided on the backplane. The onboard memory and storage support local execution of interface pages while keeping operating data and screen resources readily available.

The visualization section employs a 12.1 in active-matrix screen with a native resolution of 800 × 600 pixels, presenting up to 262,144 colors for detailed process graphics. User interaction is achieved through the resistive touch screen, eliminating physical keys and allowing direct navigation through menus and machine pages. The aluminum front bezel measures 350 mm wide by 290 mm high and carries a IP65 rating, so wash-down spray and airborne dust cannot enter from the operator side; the rear housing remains IP20, which is suitable for protected cabinet interiors. The slim profile aids in retrofits where panel depth is restricted, and the front-access layout helps keep routine operation centered at the machine interface.
