The Bosch Rexroth VT-SSPA1-50-1X/V0/0-24 (R901005414) is a valve amplifier designed for proportional valves with solenoids that lack position feedback. It features a compact design that enables quick installation and commissioning, and it is specifically tailored for assembly on valves with a base according to EN standards, ensuring compatibility and ease of integration. The electrical connection for this device utilizes a connector pole PE conforming to EN specifications, and the unit operates with a supply voltage of 24 VDC. This plugin amplifier can be rotated in 90-degree increments for versatile mounting options on the solenoid. The command value input ranges from 0 to UB volts, with a proportional solenoid current in response to command values between 0 and UB volts. For values above a certain threshold up to UB, the solenoid current remains nearly constant according to the Imax setting, which is beneficial for switching applications. The VT-SSPA1-50-1X/V0/0-24 includes a ramp generator that controls the rate of increase or decrease in control output, with separate adjustments available for ramp-up and ramp-down times. This feature helps mitigate switch-on and switch-off impulses in switching operations. Additionally, this model offers an adjustable characteristic curve with linear progression up to a certain command value. Zero point adjustments can be made using potentiometer Z, while maximum value corrections are possible through potentiometer G. The power output stage of the VT-SSPA1-50-1X/V0/0-24 is freely clocking; its frequency can be regulated via potentiometer f based on various factors such as current level, operating voltage, and controlled solenoid impedance. This regulated current signal output ensures precise control over the connected hydraulic system. In summary, Bosch Rexroth's VT-SSPA1-50-1X/V0/0-24 offers robust control capabilities for hydraulic systems requiring proportional valve operation without position feedback. Its diverse set of features like adjustable ramps, characteristic curves correction capabilities, and regulated output stage make it suitable for various industrial applications demanding precision and adaptability.
