Product Description

Bosch Rexroth specializes in manufacturing products used in industrial motion control like servo drives, servo motors, and servo controllers. These products are used across different manufacturing fields, including assembly technology, electric drives and controls, gear technology, and industrial hydraulics. Valve amplifiers are products with vast amplifications in hydraulic and electrical systems designed by this company.

The VT-VSPA1K-1-1X-002-30SEC is a valve amplifier designed and manufactured by Bosch Rexroth, which is used to control all direct and pilot-operated proportional pressure valves without electrical position feedback. It has one solenoid as its actuating element, and its solenoid conductor is protected against potentially harmful conditions like short circuit. There is also a cable break detection feature for current input of 4 to 20 mA in this model. It has a differential input or non-isolated inputs used to preset command values and additional command value input of 0 to +9V. Furthermore, it has a ramp generator that is separately adjustable for upwards and downward directions. The setting range of its ramp time ranges from 30ms to 1ms.

There is reverse polarity protection which ensures that the VT-VSPA1K-1-1X-002-30SEC is not damaged if the power supply polarity is reversed. It also has a clock power output stage with the clock frequency dependent on its setting. With its LEDs, users are informed of its operation status, and faults are easily detected. The design of this valve amplifier is a Euro card of 100mm width and 160 mm length, following the guidelines of DIN 4194. Its ideal operating voltage is 24VDC. For adequate function, it should be stored at a temperature range of -25°C to 85°C and operated at a temperature range of 0°C to 50°C.
