Product Description:
The VT 5041/3 is an input/output interface card produced by Bosch Rexroth Indramat for installation in the VT-5000 I/O Cards series. As a plug-in module, it fits into a standardized 19-inch rack to relay sensor signals and drive proportional solenoids inside automated hydraulic or motion control systems. The card conditions low-level feedback and supplies load current, allowing PLCs or higher-level controllers to manage valve positions, pressure transducers, or limit switches without extensive discrete wiring.
The board follows the Eurocard format and measures 100 × 160 mm. The card occupies 7 TE of rack width, so it fits directly beside adjoining Rexroth motion cards without leaving unnecessary gaps. All field and backplane connections are made through a 32-pin male multipoint header built to the DIN 41612 Design D pattern, ensuring mechanical alignment with standard rack connectors. Internal signal processing monitors a Dm2 channel that reaches 3.6 V, while a separate Iw9 path operates at 1 V for linear feedback scaling. The front plate measures 128.4 mm above the card guide, and an enable input on that plate becomes active once the control lead exceeds 12 V. Typical operation draws 0.6 A, while peak demand can reach 1.25 A when multiple outputs are active.
Power is supplied through a nominal 24 V DC bus, with the card remaining functional down to a lower limit of 21 V and tolerating surges up to 35 V. A square-wave generator operating at 5.4 kHz shapes the pulse-width modulated drive that the output stage delivers to the connected valve coils. Each channel can supply as much as 2.5 A of solenoid current without exceeding thermal limits, allowing the module to actuate high-force proportional valves directly. Even with the optional LED display installed, the assembly weighs only 0.21 kg, which reduces the load placed on the card guide during installation and handling.
