VT-VPCD-1-1X/V0/1-C-1

Product Description

Bosch Rexroth is a pioneer designer and manufacturer of future-proof devices for applications in industrial hydraulics. It is the creator of the closed-loop control system with HS4 control and the VT-VPCD digital amplifier cards, which are also part of this system.

The VT-VPCD-1-1X/V0/1-C-1 is a model of the VT-VPCD digital amplifier cards by Bosch Rexroth. Like others in the series, it is a double-sided printed circuit board in the Euro-card format, 100mm in width and 160mm in length. Its primary function is the implementation of the electrical functions required for the HS4 control, which ensures the electrohydraulic closed-loop control of swivel angle and pressure. It also plays a crucial role in limiting the power of variable displacement axial piston pumps. To perform these operations, this amplifier card works with a nominal supply voltage of 24 VDC with +40% to –10% tolerance. Its scanning rate is 2ms, while its connector type is a 64-pin male connector in line with DIN 41 612, form G.

An RS232 serial interface is present on the front panel of the VT-VPCD-1-1X/V0/1-C-1 as a 9-pin D-sub socket. It aids the configuration of the digital amplifier with the user-friendly BODAC program for PC. This software program can be downloaded for free from the official Bosch Rexroth site and used to commission the card as desired. It is easy to use because its program windows, operating principle, and integrated menus are designed to suit the requirements of the digital amplifier. This model has a clocked and current-regulated valve output stage and ramp times for swivel angle and pressure command values. It also has LEDs for signaling its operating states.
