Product Description
Rexroth 0811405143 VT-SSPA1-525-22/V0
The Rexroth 0811405143 VT-SSPA1-525-22/V0 is an analog servo solenoid amplifier card designed for controlling proportional valves with electrical position feedback. This Eurocard format amplifier provides precise and responsive control by converting an input command signal into a proportional output current for the valve’s solenoid. It features an integrated ramp generator for smooth acceleration and deceleration of the valve spool, an enable input, and a “ready for operation” output. This amplifier is commonly used in industrial hydraulic systems requiring accurate control of flow or pressure, ensuring reliable operation of proportional valves.
