Product Description:
The VT-VSPA2-50-1X-T5 is a plug-in proportional amplifier card from Bosch Rexroth Indramat and belongs to the VT-VSPA Proportional Amplifiers series. Designed for rack installation, the board converts low-level command voltages into a precisely metered solenoid current, giving hydraulic directional or pressure valves the linear response required for repeatable machine motion in presses, molding cells, and general automation assemblies. The unit also includes enable logic and ramp generation so motion controllers can start or stop hydraulic axes without external circuitry. This arrangement helps the valve respond smoothly to changing command signals during positioning, pressure control, and speed-related hydraulic functions.
With a Eurocard footprint of 100 x 160 mm, the unit fits a 3U rack and engages the backplane through a 32-pin DIN 41612 Form D connector for signal and power distribution. The control electronics run from a 24 VDC supply, and the amplifier disengages when the input falls below 22 V while withstanding surges up to 35 V. Internal stabilizers provide a ±9 V reference to the analog sections, which helps keep signal handling consistent across the control stages. Steady-state current draw stays under 1.2 A, keeping overall input power below 30 VA, and overload protection is provided by a 2.5 AT fuse on the front edge. The card’s 0.13 kg mass minimizes stress on slide-in guides and supports secure installation in densely populated racks.
The output stage delivers up to 1.5 A of controlled solenoid current, adjusted by a pulse-width-modulated carrier running at 220 Hz to reduce audible noise in hydraulic valves. Command signals are accepted through a differential input with 100 kΩ impedance, while single-ended reference sources use a separate input load of 100 Ω. An enable line activates the amplifier only when the terminal rises above 8.5 V, providing an interlock for machine safety chains. Five selectable ramp generators shape acceleration and deceleration so hydraulic movement remains smooth during starts, stops, and command changes. Differential signal handling also helps reduce the effect of electrical interference when the card operates near other control hardware in a machine cabinet.
