Product Description:
The VT-VSPA1-1-F10 is a plug-in proportional amplifier card from Bosch Rexroth Indramat's VT-VSPA Proportional Amplifiers series. Installed in valve control racks, the board converts low-level command signals into regulated solenoid currents so hydraulic proportional valves can follow electronic references in industrial automation systems. It is intended for hydraulic control tasks that require stable electrical output and repeatable valve response during machine operation. Because the card regulates current at the valve coil, it helps maintain consistent actuator behavior as command conditions change.
The board follows the DIN 41494 Eurocard format and measures 100 x 160 mm, allowing direct insertion into standard 19-inch subracks. Electrical interfacing is handled through a 32-Pin Form D edge connector that carries power, command, and feedback lines. Two separate voltage inputs are available for reference generation: command channel 1 accepts up to +9 V, while channel 2 can reach +10 V. An alternative current reference of 20 mA is also supported for systems that rely on loop transmitters. Internal trimming is performed by four potentiometers that allow output scaling, ramp adjustment, and offset nulling without external tools. The output stage is a current-regulated, clocked amplifier that modulates the solenoid with high-frequency pulses to maintain linear force. A 2.5 A slow-blow fuse on the card protects the supply rail, and the normal operating voltage for the electronics is 24 VDC.
The power section works within a supply window from +22 V to +35 V, providing tolerance for plant-level fluctuations. Under full dynamic demand, the card draws up to 1.8 A, which translates to a maximum apparent load of 50 VA on the control cabinet supply. Reliable operation is specified between 0 °C and +50 °C, and the storage or transport range extends from −25 °C to +85 °C. The populated PCB weighs only 0.1 kg, so it places little load on card guides during installation and operation.
