Product Description:
The VT-VSPA2-1-1X-T1-003 is a proportional amplifier card produced by Bosch Rexroth Indramat for the VT-VSPA Proportional Amplifiers series. Designed for plug-in installation on standardized Eurocards, it receives control references from a PLC, shapes them through internal signal conditioning, and then feeds modulated current to proportional hydraulic valves. By managing valve coil energy with high linearity, the board allows precise pressure or flow regulation in presses, test rigs, or material-handling axes, while also isolating the control system from inductive load transients.
Its physical footprint follows the Eurocard format at 100 x 160 mm, so the card fits directly into a DIN-compatible rack without spacers. The electronics operate from a nominal bus voltage of 24 VDC, yet remain functional down to 18 V and up to 35 V, which covers typical mobile and stationary power sources. Internal converters and signal processors restrict consumption to <50 VA, and the board draws less than 2 A of supply current even during full-scale output. A ramp input resistance of 10 kΩ shapes the rise and fall times, while the differential command channel presents more than 50 kΩ of impedance to limit loading of upstream analog modules.
The current-programmed driver stage meets valve specifications with a load requirement of 100 Ω at the current input, ensuring full stroke without external boosters. To preserve signal integrity, the differential input shows an impedance greater than >50 kΩ, while the front-panel potentiometer channel exceeds >100 kΩ, minimizing interaction when multiple cards share the same reference source. Over-current or wiring faults are cleared by a replaceable 2 A fuse, and overall supply demand is limited to less than 2 A. Together with the 10 kΩ ramp network, these parameters give predictable acceleration profiles and protect both the power supply and the connected hydraulic actuators.
