Product Description:

The VT-VSPA2-1-2X-V0-T1 is a proportional amplifier card produced by Bosch Rexroth Indramat within the VT-VSPA Proportional Amplifiers series. This plug-in module conditions analog command signals and supplies controlled current to pilot-stage solenoids, enabling closed-loop positioning of directional or pressure valves in automated hydraulic systems. By converting electrical references into proportional valve actuation, the card forms an interface between PLC control layers and field-level hydraulic actuators. In rack-mounted installations, the VT-VSPA2-1-2X-V0-T1 occupies a single Eurocard slot and mates with a standardized backplane, which keeps the module aligned with the control rack and supports orderly integration into modular hydraulic assemblies.

The card operates from a nominal supply of 24 VDC, with undervoltage monitoring below 18 V and overvoltage tolerance up to 35 V. These limits protect downstream valve coils against irregular supply conditions and help maintain predictable amplifier response during supply fluctuations. An output stage rated for 2.5 A delivers the drive current demanded by most NG6 and NG10 proportional valves while remaining within the module’s thermal design. Overall energy draw stays under 50 VA, so cabinet power budgeting remains straightforward even when several cards are installed. Physical size is held to 100 × 160 mm, matching IEC 60297 Eurocard dimensions and allowing dense stacking inside standard 19-inch subracks.

At just 0.17 kg, the module imposes minimal load on card guides, which helps maintain vibration resistance in mobile machinery panels. The differential command channel provides a span of ±10 V ±2 %, giving controllers a symmetrical range for bidirectional valve operation and allowing smooth reversal between positive and negative command states. A monitored feedback output of ±2.5 V ±2 % supports diagnostics or cascaded loops without extra signal conditioners, making it easier to observe commanded behavior from external control circuits.
