Product Description:

The VT-MSPA 1-508-10-V0 is an analog single-axis drive card in the VT-MSPA Drives series from Bosch Rexroth Indramat. Designed for panel integration, it converts low-level command signals into regulated current for proportional solenoids, allowing precise hydraulic valve actuation in automated machinery and test rigs. It links a potentiometric command source to an onboard current controller, so the module can supply the coil with controlled power and help flow, pressure, or directional behavior follow an external reference. This layout makes the card suitable for compact control cabinets where stable valve response and straightforward wiring are required.

The reference channel accepts a 10 kΩ command potentiometer and is buffered by an input stage with a resistance of 100 kΩ, which helps reduce loading on upstream electronics. A regulated supply of 24 VDC powers the card, and internal draw is limited to 1.25 A so the module can be integrated into modest cabinet power distribution. Total power consumption does not exceed 30 VA, which helps when planning thermal load inside dense enclosures. Control output is produced by a clocked current controller that uses pulse-width modulation to maintain smooth coil excitation while keeping dynamic response high. The electrical requirements of the card should be supported by the associated power supply and field wiring.

The module has one output stage rated for a solenoid current of 0.8 A and works with a fixed reference supply of +10 VDC and a selectable reference current of 10 mA. Its mechanical format follows the EN 60715 rail profile, and the overall size is 86 × 110 × 70.5 mm, which supports installation in compact assemblies. The installation weight is only 0.31 kg, so the unit places little load on standard DIN rails. A 10-pole screw terminal simplifies field wiring, and the 25 VA solenoid power output supports many NG06 and NG10 proportional valves without requiring an external booster stage.
