Product Description:
Bosch Rexroth Indramat manufactures the VT-VSPA1K-1-1X-002-30SEC proportional amplifier, a plug-in card within the VT-VSPA Proportional Amplifiers series. The board interfaces between a machine controller and a proportional valve, translating command voltages into regulated coil current so hydraulic flow or pressure can be varied smoothly in automated presses, plastics machines, and test rigs. Its standardized Eurocard format allows the module to fit neatly into compatible rack-based control systems and keeps panel integration straightforward in compact hydraulic cabinets.
The card is energized from a 24 V DC supply, and normal operation remains stable across a +40% / -5% variation, allowing tolerance to industrial bus fluctuations. An onboard fuse rated at 2.5 A T guards the input rail, while internal current control limits the solenoid loop to a maximum of 1.8 A so the output stage remains protected during operation. Overall power draw does not exceed 50 VA, which helps limit heat buildup inside the enclosure. The design uses a single analog control channel and operates without electrical feedback, so output behavior follows the commanded input in an open-loop arrangement. Master card architecture allows this module to supervise subordinate boards in multi-card racks, while short-circuit protection and cable-break detection interrupt coil energization when wiring faults occur.
For installation, the board fastens through holes sized for a 4.5 mm screw, and field wiring terminates on a 16-pole terminal strip. Operating status is shown by the green H2 LED, which illuminates when drive current flows, giving a quick visual indication that the output stage is active. Command scaling is handled by the analog input stage, and adjustments are accessed directly on the PCB because the module has no front plate. The compact card width lets the amplifier sit flush with neighboring units, and the layout is intended for operation with a single solenoid coil.
