Product Description:

The VEP40.4DBU-512NC-MAD-1G0-NN-FW is an embedded human-machine interface built by Bosch Rexroth Indramat for the VEP Embedded Terminals series. Installed on control enclosures, it provides a sealed front panel for operator input and real-time visualization of controller data in industrial automation cells, packaging lines, and material-handling stations. The terminal combines display, touch input, and communication functions in one cabinet-mounted unit, so it can serve as the local operating point for machine status, alarms, and process interaction.

This terminal operates from a stabilized input of DC 24 V; during power-up it draws a 7 A pulse for 6 ms and then remains within a continuous limit of 1.5 A. Internal conversion supports the terminal's power demand, and a capacitor pack performs short-time UPS duties so process data can be saved when the supply drops. The TFT display measures 12.1 in and has a native resolution of 800 x 600 pixels. Color depth reaches 262,144 shades, enabling clear differentiation of status icons and trend graphs. The 5 mm aluminum front is sealed to IP65, allowing washdown with low-pressure water jets, while the rear housing retains an IP20 rating for cabinet-mounted electronics.

The device carries 512 MB of RAM for runtime applications, recipe storage, and alarm buffers. Diagnostic data can be retrieved through a non-isolated service interface that uses RS-232C, 9600 baud, which simplifies cable connection. For plant networks, a fieldbus port supports PROFIBUS DP, 12 Mbaud, and the lines are potential-free to help protect neighboring nodes from ground loops. The diagnostic and fieldbus circuits are backed by a short-time UPS, ensuring message integrity during brief brownouts. Front-panel sealing keeps moisture away from the touch surface, and the inrush limiter reduces stress on upstream 24 V supplies. Overall power consumption never exceeds 36 W, keeping thermal load low inside sealed cabinets.
