The Bosch Rexroth VT-SSPA1-508-2X/V0/0 (0811405144) is a valve amplifier designed for the precise control of proportional valves without electrical position feedback. This compact device facilitates quick assembly and commissioning, streamlining the integration process into various control systems. It is specifically engineered to operate with a single solenoid and is directly connected to the solenoid plug, ensuring a secure and efficient connection. The unit's functionality includes an LED indicator that confirms the presence of supply voltage, ensuring operational readiness. The command value input accepts a 0 to 10 V signal, allowing for fine-tuned control over pressure valves. Users can adjust critical settings such as zero point and sensitivity to match specific application requirements. Additionally, the amplifier features a differential input for enhanced signal integrity. For applications requiring gradual changes in valve position, an adjustable ramp function is available to modulate the command value smoothly over time. This feature is particularly useful in scenarios where sudden changes in valve position could be detrimental or where a soft start-up is required. Another customizable aspect of this valve amplifier is its dither frequency. Dithering helps prevent valve stiction and promotes more accurate positioning. While the dither amplitude comes preset from the factory at an optimal value for general use cases, it can be adjusted to accommodate special applications as needed. Operating on a 24 V power supply, this Bosch valve amplifier offers flexibility and precision in controlling proportional valves across various domains where reliable and accurate hydraulic or pneumatic control is essential. Its robust design and adjustable parameters make it suitable for a wide range of industrial applications that require meticulous valve operation without position feedback.
Valve amplifier for proportional valves with 1 solenoid without position feedback
for controlling pressure valves without position control. Compact design. Quick assembly and short commissioning times.
Unpacked Weight: 0.2221 kg
The amplifier is used to control proportional valves without electrical position control.
It is connected directly to the solenoid plug of the valve. The connection cable on the control side (UB, command value) is lead through a cable gland and connected.
An LED signals the available supply voltage. Depending on the type of the amplifier, the command value presetting is a voltage 0...10 V or a current 4...20 mA.
The command value can be adjusted with regard to zero point and sensitivity. With voltage presetting, a differential input is available.
In addition, the command value can be led over a ramp.
To allow for adjustment to special applications, the dither amplitude was designed variably.
Upon delivery, the dither amplitude has already been set to a perfect value so that another adjustment is only necessary in the above-mentioned special cases.

The plug-in amplifier may only be unplugged and plugged when de-energized. The distance to aerial lines, radios and radar systems must be sufficient (> 1 m). Do not lay solenoid and signal lines near power cables. For signal lines and solenoid conductors, we recommend using shielded cables. The cable shield must be connected to the control cabinet extensively and as short as possible.
Preparation of the connection cable (“Preparation of the connection cable” graphic) Lead the cable through the cable gland and connect it to terminal St 1. Applying the supply voltage → LED (green) is illuminated. Zero point adjustment → poti P3 with minimum command value presetting (“Zero point and sensitivity” graphic) Sensitivity adjustment → poti P2 with maximum command value presetting (“Zero point and sensitivity” graphic) Dither frequency adjustment → poti P4 (“Dither frequency” graphic)
The dither frequency is already correctly adjusted when supplied. For special applications, a correction may be necessary. In this case, please contact DC-IA/PRM12. Ramp time adjustment → poti P1 (“Ramp time” graphic)
