VT-5004-24/R1E

The VT-5004-24/R1E I/O card from Bosch Rexroth Indramat is a member of the VT-5000 IO Cards series and delivers precise analog control in demanding industrial environments. This module operates at 24 V DC with an Operating Voltage tolerance of +40%/–10% (21.6–33.6 V) and features a Current Consumption of 0.6 A nominal (1.25 A max). Packaged in a Euro-card format, its Card dimensions measure 100 × 160 mm (Euro-card, DIN 41 494) with a front panel height of 3 HE (128.4 mm) and width of 1 TE (5.08 mm) solder, 7 TE (35.56 mm) component. The robust Connector Type is a 32-pin male, DIN 41 612 Form D multipoint connector, ensuring reliable signal paths in high-vibration installations. Operating reliably from 0 to 50 °C, this module strikes an optimal balance between compact footprint and industrial robustness.

Technical capabilities of the VT-5004-24/R1E include multi-channel analog inputs and outputs for fluid power control. The Actual Pressure Input (pist) accepts 0–10 V signals into Re > 50 kΩ with RB = 100 Ω, while the Pressure Command Input (psoll) also handles 0–10 V, providing seamless setpoint definition. Built-in modulation oscillators run at an Oscillator frequency of 5.4 kHz with dual amplitude settings of 1 V (IW9 swivel) and 3.6 V (DM2 valve), allowing precise PWM generation. The Power Command Input (p·sw) max mirrors the pressure input spec of 0–10 V for synchronized control of external valves. Additionally, the Auxiliary Voltage for External Use supplies ±15 V at up to 10 mA to drive ancillary sensors or logic.

Operational features deliver high fidelity and reliability in continuous service. All analog inputs exhibit high input impedance (Re > 50 kΩ) to minimize loading on upstream sensors. The module’s Output Stage Solenoid Current capability of Imax 2.5 A, R20 = 2 Ω supports direct solenoid drive without external amplifiers. Pressure and swivel angle outputs provide Pressure signal output 0–10 V and Swivel angle signal output ±10 V (±100%) for full-range actuator displacement feedback. Internal transient protection and regulated current stages ensure stable performance under electrical stress. For extended storage or transport, the card withstands temperatures from Storage temperature range –25 °C to 85 °C. Weighing just 0.15 kg, it simplifies handling and rack loading.

Integration into industrial automation systems is streamlined by the VT-5004-24/R1E’s Euro-card form factor and standardized DIN connectors. The module mounts easily within 19″ racks conforming to DIN 41 494, and its 32-pin Form D interface reduces wiring complexity. Compatibility with the Bosch Rexroth Indramat VT-5000 family ensures seamless parameterization and diagnostics. Typical applications include hydraulic valve control, proportional pressure regulation, and electrohydraulic servo drives in manufacturing, mobile machinery, and process automation where precision and reliability are paramount.
