VT 5041-31/2-0

The Bosch Rexroth Indramat VT 5041-31/2-0 represents a high-performance addition to the VT-5000 IO Cards lineup, engineered by Bosch Rexroth Indramat for demanding industrial automation environments. This Analog Control Electronics Card operates at a Nominal Voltage of 24 VDC and accepts an Analog Input Pressure Command of 0 to 10 V for precise hydraulic pump regulation. Designed to interface with SYDFE1-controlled axial piston pumps such as the A10VSO, the VT 5041-31/2-0 delivers stable pressure and swivel angle control under varied load conditions. With a compact form factor and front-panel status LEDs, this card provides immediate visual feedback of operational states without the need for external diagnostics. Its rugged design supports a continuous Rated Current Consumption of 0.6 A and a Maximum Current Consumption of 1.25 A, ensuring reliable performance in industrial settings.

Featuring a comprehensive electrical interface, the VT 5041-31/2-0 integrates Communication Interfaces including Ethernet and RS485 for seamless connectivity to supervisory control systems. The card’s Input Resistance (RB) of 100 Ω on the Pressure Value Input channel accommodates both Voltage: 0 to 10 V and Current: 0 to 20 mA, 4 to 20 mA signals, enabling versatile feedback from external transducers. Power modulation is managed via dedicated Power Control Input Values of 0 to 10 V (p × SW) max and ±10 V for SWACT master, while Swivel Angle Command Values support both Standard: ±10 V and Regenerative: 0 to 10 V control modes. Internally, a Multi-axis motion controller architecture governs pump displacement and pressure commands with high dynamic accuracy. The card operates within a Temperature Range of -10°C to +50°C and under Voltage Limits between 21 V and 35 V, optimizing tolerance to electrical and thermal stress.

Operational efficiency is enhanced by built-in functions such as a Pressure-Dependent Leakage Compensation mechanism, which can be switched off for system diagnostics. A dedicated Minimum Value Generator ensures that the lower thresholds for both pressure and swivel angle commands are maintained, preventing control dead zones. Six high-contrast LEDs on the front plate deliver real-time status of power, enable, pressure reference, actual pressure, swivel command, and fault conditions to simplify troubleshooting. The card’s enable input requires a PLC activation voltage above 12 V, offering secure integration into automated safety circuits. Its inductive transducer compatibility supports IW9 and DM2 sensors for swivel angle and valve regulation, respectively, delivering ±4 mm and ±0.6 mm resolution in critical feedback loops.

Integration of the VT 5041-31/2-0 into existing hydraulic systems is straightforward due to its compliance with Bosch Rexroth Indramat mounting standards and its adherence to the VT-5000 IO Cards service profile. Engineers can leverage the card’s native Ethernet and RS485 ports to connect directly to distributed control systems or higher-level SCADA platforms. The versatile input/output configuration and programmable control logic make it suitable for applications ranging from mobile hydraulics to factory automation, including injection molding, machine tools, and mobile construction equipment. With its robust electrical design and precise analog control capabilities, the VT 5041-31/2-0 ensures optimized pump performance and simplified system integration across diverse industrial applications.
