Bosch Rexroth VT-VSPA1-2-1X/V0/0 proportional valve amplifier

Bosch Rexroth VT-VSPA1-2-1X/V0/0, material number R900782310, is an analog Eurocard amplifier for DBET proportional pressure valves, series 6X, or a suitably configured universal pressure-valve application. The standard option 0 is distinct from the A4 four-command call-up version. Differential 0–10 V and 4–20 mA command inputs are provided.

The RE30115 reference specifies nominal 24 V DC supply within 18–35 V DC and a clocked output-stage capability of 0–1.9 A. Output current, corrective characteristic and clock configuration must match the actual valve; these capabilities do not establish delivered parameter settings. Up/down ramps are separately adjustable over 20 ms–5 s, switchable to 0.2–50 s. The permitted operating temperature is 0–50 °C.

The current factory material card describes a 32-pin connection, while RE30115, February 2006, specifies a 48-pin form F connector for this type. Confirm the actual connector and pin assignment with the manufacturer before installation. The selected reference drawing is not a binding connector drawing for this article. Card holder, power supply and valve are separate components. The manufacturer photograph represents the amplifier series.
