Product Description:
The VT-VSPA1-1-D10 is a plug-in proportional amplifier card developed by Bosch Rexroth Indramat for the VT-VSPA Proportional Amplifiers series. Installed in a standard Eurocard rack, the module converts low-level command voltages into controlled valve currents so hydraulic actuators follow electronic set-points. Its circuitry adds selectable ramp shaping and onboard protections, letting machine builders integrate precise pressure or flow regulation without external conversion stages. By occupying a single slot, it supports compact drive manifolds in presses, molding machines, and test rigs.
Primary power is provided by a regulated 24 VDC rail, while auxiliary electronics reference a balanced ±9 V supply so that offset amplifiers remain linear. Despite multiple output stages, total dissipation is limited to 50 VA, and the board draws no more than 1.8 A under worst-case load. Input 2 can accept up to +10 V, and its 100 Ω input resistance helps protect the source device. A ramp generator lets command transitions extend to a maximum of 5 s, smoothing hydraulic motion, and overload protection is handled by a 2.5 A time-lag fuse. The front edge mates to a 32-pin male Form D connector that carries power, command, and feedback lines, and each auxiliary rail can furnish 25 mA to external transducers.
The supply tolerance ranges from 22 V to 35 V, allowing the card to remain functional during input fluctuations. When a rapid response is required, the internal ramp can be shortened to 30 ms, letting the connected valve follow abrupt set-point changes. Thermal limits extend from 0 °C to +50 °C, so cabinet ventilation must keep the ambient temperature within that range. The board occupies a compact footprint of 100 × 160 mm, which simplifies high-density rack layouts.
