VT 5011 S44
The Bosch Rexroth Indramat VT 5011 S44 IO card is a high-performance member of the VT-5000 IO Cards series designed to deliver precise control and robust operation in demanding industrial environments. This module operates at an Operating voltage of 24 V DC (+40%/–10%) with a Supply lower limit of 21 V and an Supply upper limit of 35 V, ensuring compatibility with varied power conditions. Key capabilities include a maximum solenoid output current of 2.5 A and a peak current consumption of 1.25 A, providing reliable actuation of high-power loads. Compactly built in a 100 × 160 mm Euro-card format, the VT 5011 S44 simplifies integration into existing automation racks. Its built-to-last construction and predictable performance make it a preferred choice for system integrators and machine builders.
Detailed technical specifications illustrate the VT 5011 S44’s versatility and precision. The card’s analog inputs include a 0–10 V analog pressure actual input voltage (Re > 50 kΩ) and a 4–20 mA pressure actual input current (RB = 100 Ω). Command inputs encompass a 0–10 V pressure command (Re > 50 kΩ) and a ±10 V swivel angle command input (Re > 50 kΩ). Auxiliary power is delivered via a ±15 V ±6% output at up to 10 mA, while the pressure signal output is rated at 0–10 V. Oscillator outputs feature an amplitude of 1 V on port 12a/14a and 3.6 V on port 8a, operating at an approximate oscillator frequency of 5.4 kHz. The enable input level requires a minimum of >12 V to activate I/O functions.
Operational features emphasize the VT 5011 S44’s stable performance under continuous use. It maintains a base current consumption of max 0.6 A during normal operation and tolerates peaks up to 1.25 A, minimizing thermal stress. Solenoid valves benefit from the robust 2.5 A max solenoid output current (R20 = 2 Ω). Feedback loops achieve high fidelity through the ±10 V swivel angle signal output (–100% to +100%) and a pressure signal output of 0–10 V, enabling fine-tuned control in dynamic systems. The card’s oscillator sections support precise timing for valve actuation with minimal jitter at 5.4 kHz.
System integration is simplified via the standardized Euro-card form factor and industry-standard I/O levels, making the VT 5011 S44 ideal for hydraulic power units, pneumatic control stations, and general machine automation. Its compatibility with Bosch Rexroth Indramat controllers allows seamless communication over established fieldbus and backplane networks. Target applications include complex assembly lines, process control systems, and mobile machinery where reliable analog control and valve operation are critical. The VT 5011 S44 delivers a balanced combination of precision, durability, and ease of integration for modern industrial automation architects.
