VT 5041-23/1-0V

The Bosch Rexroth Indramat VT 5041-23/1-0V Valve Amplifier Card belongs to the renowned VT-5000 IO Cards series and is engineered for precise hydraulic actuator control in demanding industrial environments. This VT 5041-23/1-0V card supports proportional directional valve operation with an input voltage range of 0 to ±10 V and delivers a solenoid current output of 2.5 A through a robust 32 Pin Male Multipoint Connector. Built to DIN 41612 and DIN 41494 standards, the module integrates seamlessly into electronic control systems while ensuring mechanical compatibility. The compact Euro card form factor measures 100 × 160 mm, facilitating straightforward installation in standard rack assemblies. Designed and manufactured by Bosch Rexroth Indramat, this Valve Amplifier Card provides a reliable interface for pressure, swivel angle, and power command signals.

Performance optimization is achieved through high-precision analog command inputs for Pressure, Swivel angle, Power control, each with an input resistance exceeding 50 kΩ to minimize loading effects. An Integrated Oscillator Frequency of 5.4 kHz provides stable PWM generation for proportional valve actuation, while an amplitude of 1 V on IW9 and 3.6 V on DM2 outputs ensures accurate signal modulation. The solenoid coil is driven through a 2 Ω resistance network, offering consistent current regulation under variable load conditions. Directional control pressure is rated up to 315 bar, enabling the card to manage high-pressure hydraulic circuits with precision. Auxiliary voltage rails of ±15 V (±2 % to –6 %) supply up to 10 mA, supporting external sensors and control electronics without additional power modules. Advanced internal controllers include a differential amplifier for improved stability and a pressure dependent leakage compensation function for enhanced actuator positioning accuracy.

Reliability is further enhanced by built-in reverse polarity protection on the voltage supply and a self-timed output stage that prevents uncontrolled valve movement during fault conditions. The card’s die-cast alloy body construction ensures excellent thermal dissipation across an operating temperature range of -40 °F to 250 °F, making it suitable for harsh industrial settings. Integration is simplified through the standardized 100 × 160 mm Euro card footprint and connector placement, allowing drop-in replacement or system expansion in existing VT-5000 racks. Typical applications include mobile hydraulics, machine tools, and process automation where proportional directional control is critical. With its precise control loop, high overload capacity, and compliance with industry standards, the VT 5041-23/1-0V valve amplifier card is an ideal solution for advanced industrial automation projects.
