Product Description:
The VT-VSPA1K-2-1X-V0-0 is a plug-in proportional amplifier card produced by Bosch Rexroth Indramat for the VT-VSPA Proportional Amplifiers series. The board conditions analog command signals and drives proportional hydraulic valves, allowing machine controllers to adjust flow or pressure in real time. It installs in a standard 32-pin Eurocard rack, so the valve electronics can be replaced or configured without disturbing field wiring.
Mechanical dimensions follow the Eurocard pattern, with a length of 160 mm and a width of 100 mm; these limits keep board spacing predictable and leave clearance for airflow. The differential command input presents a 100 Ω load, enabling accurate set-point processing from PLC current loops, and the fixed resistor keeps scaling stable over temperature. A replaceable 2 A fuse protects the supply rail against accidental shorts, and power is delivered at 24 VDC through the backplane connector. Because the input stage senses current rather than voltage, wiring resistance has little influence on calibration. The fuse rating also sets a safe inrush limit when multiple cards share a common supply rail. Internal circuitry filters and linearizes the command signal before driving the valve coils, so output force tracks the requested value even under dynamic load changes.
Voltage tolerance is broad, and the amplifier remains functional from 18 V up to 35 V, preventing nuisance trips during low-bus conditions or regenerative surges. Under maximum demand it draws 2 A, giving a thermal budget of 24 VA max; staying below this level keeps component temperatures within normal operating margins and supports cabinet ventilation. The card also furnishes an isolated reference of +10 V ± 2% for potentiometers, feedback sensors, or external ramp generators, letting a complete valve channel operate without an auxiliary power supply.
