Product Description:

The VPB40.3D1Q-4G0NN-DSD-DN-NN-FW belongs to the VPB IndraControl PC Units series manufactured by Bosch Rexroth Indramat. This fanless cabinet-mounted computer acts as the control core for modular machines, executing motion sequences, visualizing process data, and bridging field networks to higher-level systems. Its housing measures 321 mm in height, 92 mm in width, and 181 mm in length, so it fits on DIN rails behind the electrical panel door without occupying operator space. Powered from a 24 V DC supply, the unit replaces traditional rack controllers with a compact PC architecture tailored for industrial environments.

Processing performance is anchored by a Core i7-620M 2.66 GHz CPU that delivers dual-core hyper-threaded computation for deterministic control loops. The system is paired with 4 GB of DDR3 RAM to hold the operating system, PLC runtime, and user programs. Persistent storage resides on a 1 x 320 GB HDD, allowing recipe and log retention across power cycles. Two independent gigabit ports, specified as 2 x Ethernet TCP/IP (1 Gbit/s), connect the controller to machine networks and plant IT. Internal buses expose 2 x PCI, 2 x PCIe slots so motion cards or fieldbus interfaces can be added, while six USB 2.0 ports support service peripherals. During nominal operation, the electronics draw 160 W, a figure used for cabinet heat calculations and UPS sizing. The input range of 19–30 V DC protects the computer from supply variations that occur during motor inrush or battery float.

The unit withstands continuous vibration up to 1 g and transportation shocks reaching 15 g, so it can remain installed on moving gantries or mobile equipment. Its enclosure carries an IP20 protection rating, which provides finger-safe access and relies on the cabinet for dust and moisture shielding. Proper clearance around the cooling fins allows convection to exhaust waste heat and helps preserve processor performance during extended production cycles.
