Product Description:
The Bosch Rexroth Indramat VT-VSPA1-1-1X-001 is a proportional amplifier card from the VT-VSPA Proportional Amplifiers series. Used in hydraulic automation, the card converts low-power command voltages from a controller into regulated coil current for proportional valves, thereby stabilizing pressure or flow in closed-loop systems. Installed as a master card on a Euro-rack backplane, it links PLC logic with electro-hydraulic actuators to maintain repeatable motion and force profiles on production machinery.
The board follows the DIN 41494 Euro-card format, giving it a footprint of 100 × 160 mm; this standardized size simplifies insertion and cooling within 19-inch sub-racks. Its component side occupies 3 TE while the solder side extends only 5.08 mm, so adjacent slots remain accessible for additional modules. External wiring enters through a 32-pin male, DIN 41612 Form D header that carries power, command, and feedback lines. The nominal operating bus is 24 V DC, and internal regulators allow continuous duty anywhere between the 22 V lower limit and the 35 V upper limit without recalibration. A front panel height of 128.4 mm aligns with standard sub-rack cutouts, and clear silk-screen legends assist with service access.
An onboard linear supply produces a stable ±9 V reference for sensor and signal paths, supporting the analog method used for valve control. Peak draw stays below 1.8 A, and overall dissipation does not exceed 50 VA, allowing multiple cards to share a cabinet without overloading the backplane supply. A 2.5 A slow-blow fuse is fitted to isolate faults and protect upstream wiring. The master-card design routes calibration potentiometers to the front bezel, so ramp times and gain can be trimmed while the unit is energized. Front-access controls, standardized dimensions, and modest thermal load support integration into complex hydraulic servo systems.
