Product Description

Products used in industrial hydraulics are a core specialty of the renowned Bosch Rexroth brand. They include pump systems, self-contained actuators, accumulators, cylinders, and proportional, high-response, and servo valves. The company also designs and manufactures whole hydraulic systems with high-quality components.

The VT-VSPA1K-2-1X-V0-0 is one of the valve amplifiers designed and manufactured by Bosch Rexroth for use in its high-performance hydraulic and electrical systems. It is built for the efficient control of direct and pilot-operated proportional directional pressure control valves without electrical position feedback. To achieve this, it works with a nominal voltage of 24V DC with an allowance between +40% and – 5%. It also has a ramp generator which can be adjusted separately for upwards and downwards directions. Additionally, it is equipped with one solenoid as actuating element and a ramp time setting range of 30 ms to approximately 1 second or 5 seconds. Its differential input can be switched from voltage to current input.

Cable break protection for current input 4 to 20 mA is one of the protective features of the VT-VSPA1K-2-1X-V0-0. Others include reverse polarity protection for voltage supply and short-circuit protection, and cable break detection for its solenoid conductor. Its connector is a 16-pole terminal strip, and it is built as a Eurocard printed circuit board of 100m width and 160mm length according to DIN 41494.  The amplifier is a user-friendly device with LEDs present to serve as indicators of the device’s operating state per time. They also ensure that faults can be accurately identified and resolved, extending the service life of the amplifier. During the use of this component, the ambient temperature should be kept between 0°C and +50°C.
