The Bosch Rexroth VT-SSPA1-1-1X/V0/0-24/K24 (R901238534) is a sophisticated plugin amplifier designed for precise control in hydraulic systems. This amplifier is engineered to be mounted directly onto a valve connection base adhering to EN standards, offering flexibility in installation with the ability to rotate the plugin insert and electronics by 90° increments. It features a command value presetting that allows for proportional solenoid current within a specific voltage range, ensuring precise control over hydraulic operations. Equipped with an integrated ramp generator, the VT-SSPA1-1-1X/V0/0-24/K24 facilitates smooth transitions by controlling the ramp-up and ramp-down times separately, which is particularly beneficial for dampening switch-on and switch-off impulses in switching applications. The characteristic curve of this amplifier provides a linear increase up to a certain command value, with zero point adjustments possible via potentiometer Z and maximum value corrections through potentiometer G. The power output stage of this Bosch Rexroth amplifier operates freely clocking, where the frequency is adjustable using potentiometer f and depends on various factors including current level, operating voltage, and solenoid impedance. This feature ensures that the generated current signal matches the control output accurately while maintaining system stability by preventing excessive hysteresis or noise levels. Overall, the VT-SSPA1-1-1X/V0/0-24/K24 offers precise control with its proportional command value-current characteristic curve for specific command values and regulated adjustable maximum current for higher commands. Its design includes differential input capabilities, zero adjustment potentiometers for pilot currents, an attenuator for maximum current settings, and dither frequency adjustments – all operating effectively within a 24V voltage range.
