Product Description:
The VT-VSPA1-10-1X-V0-0 is a plug-in proportional amplifier card produced by Bosch Rexroth Indramat within the VT-VSPA Proportional Amplifiers series. Installed in a standard Eurocard rack, it conditions command signals and drives solenoids in directional or pressure control valves. By converting low-level analog inputs into a controlled current, the unit lets an automation controller vary hydraulic flow or pressure with repeatable accuracy. Its card format and ready output simplify integration into valve banks on industrial machinery.
Stable operation is based on a nominal supply of 24 VDC, with a permissible range from 18 to 35 V, so the amplifier remains functional during moderate bus fluctuations. The internal oscillator works at 330 Hz ±10%; this frequency sets the chopper rate for the output stage and minimizes dither on the valve spool. Total board demand never exceeds 2 A, while the power stage can deliver up to 1.9 A of controlled current to a single (Z)DRE 6… valve. A regulated reference of +10 V ±2% is provided for external potentiometers, and the zero adjustment trimmer allows a ±30% offset to match individual valve tolerances. A 2 A fuse protects the card from supply faults, and the ready output supplies 50 mA for system status annunciation.
This amplifier is built on a Eurocard that measures 100 × 160 mm, allowing direct insertion into 19-inch racks that follow IEC 60297. Signal and power lines are routed through a 48-pin DIN 41612 F connector, so no discrete wiring is needed on the module edge. The command channel presents a differential input impedance higher than 50 kΩ, which safeguards delicate analog sources against loading and noise coupling. Despite the integral power electronics, the board weighs only 0.15 kg, keeping cabinet mass low.
