The VT-VSPA1K-2-1X-V0-A4 is a Bosch Rexroth valve amplifier designed for managing direct and pilot-operated proportional directional pressure control valves without electrical position feedback. Incorporated in a robust, 100mm wide and 160mm long Eurocard printed circuit board, the model offers operational reliability with a host of integrated components. It operates a single solenoid actuating element, alongside an adjustable ramp generator for both ascending and descending directions. The unit operates at a nominal voltage of 24V DC, with a tolerance of +40% to -5%. Other specifications include a ramp time setting range of 30 ms to 1 second or 5 seconds, a 16-pole terminal strip for connections, and a differential input switchable from voltage to current input. The VT-VSPA1K-2-1X-V0-A4 is equipped with LEDs for fault diagnosis and real-time operational status, and reverse-polarity, short-circuit, and cable-break protections. With a weight of 0.1kg, the unit is operable between 0oC to 50oC and storable at -25oC to 85oC.
