The Bosch Rexroth VT-SSPA1-5-1X/V0/0-24 (R901024331) is a sophisticated plugin amplifier designed for precise control of proportional solenoids in hydraulic systems. This unit is engineered to be mounted directly onto a valve connection base conforming to the EN standard, with the capability of being rotated in 90° increments for optimal positioning. It features a command value presetting function where the solenoid current is proportional to the command value within a specified range, and maintains a nearly constant current beyond that range up to the power supply voltage UB, depending on the Imax setting.
Equipped with an adjustable ramp generator, this plugin amplifier can modulate the rise of the control output signal, allowing for separate fine-tuning of both up and down ramp times. This feature is particularly useful in switching applications to mitigate the effects of switch-on and switch-off impulses. The characteristic curve of this device exhibits a linear increase up to a certain command value, with potentiometers available for zero point and maximum value adjustments.
The power output stage of the VT-SSPA1-5-1X/V0/0-24 operates on a freely clocking principle where its clock frequency varies based on current level, operating voltage, and solenoid impedance. This frequency can be recalibrated using an onboard potentiometer to optimize valve performance and minimize system noise. The integral current output stage consistently generates a regulated current signal that corresponds with the control output from the summing device.
This model also includes features such as differential input capability, zero potentiometer for pilot current adjustment, command value attenuator, dither frequency potentiometer, and it operates on 24V voltage supply. It's specifically tailored for valves designated as KBPS in series X analog connector design. The Bosch Rexroth VT-SSPA1-5-1X/V0/0-24 offers precision and adaptability for complex hydraulic applications requiring reliable solenoid control.

2-conductor technology
Switching application with constant current control Ramp function upon switch-onThe “IN+” input is bridged with supply voltage (+UB) in the connector, the IN- input is bridged with supply voltage (0 V) in the connector.
The maximum current must generally be adjusted according to the solenoid information using potentiometer "G". The ramp time "ramp up" (t <) can be set within the range of tmin to 5 s.

Switching application with constant current control
Switching with low control power
Ramp function can be adjusted separately when switching the control voltage on and off
The “IN+” input is connected to the control voltage
(Us = 24 V), the “IN–” input is bridged with supply voltage (0 V) in the connector.
The maximum current must generally be adjusted according to the solenoid information using potentiometer "G". When switched off ("IN+" = 0 V or "IN+" = open), a pilot current can be set at "Z". It serves to reduce the switch-on delay, particularly with ramp. If required, this value can be adjusted between approx. 0 mA and approx. 15 % of the rated current. The ramp times “ramp up” (t <) and “ramp down” – (t >) can be set within the range of tmin to 5 s.

4-conductor technology
The “IN+” input is connected to the control signal (Us = 0...10 V/24 V), the “IN–” input to the reference potential of the control voltage.
Pilot current and maximum current are set using potentiometers "Z" and "G" prior to commissioning. The current can now be proportionally adjusted according to the control voltage between the set pilot current and the set maximum current. The pilot current can be set in the range from approx. 0 to approx. 15 % of the rated current, the maximum current can be set in the range from 0 to Imax .
