Product Description

Bosch Rexroth is a manufacturer of industrial motion control systems and drive control equipment for industrial automation and drive control applications.

The VT-VSPA1-1-11 is a valve amplifier manufactured by the company. The system is used for proportional pressure valves. The device comes with its own ramp generator that is used for separately adjusting downwards and upwards directions. Wit         h clock frequencies of 100 and 160 Hz, the system is able to quickly take automation decisions. The system comes with a differential input that is switchable from voltage to the current input. This valve amplifier is considered suitable for all direct and pilot operated proportional valves without electrical position feedback and valves that have only one actuating element and solenoid. This model operated with an additional command value input of 0 V and 9 V. The system is able to detect a cable break of the solenoid conductor and is also protected against short-circuiting.

The VT-VSPA1-1-11 weighs only 0.1 kg and has a temperature storage range between -25 °C and 80 °C. The device should only be operated between ambient air temperatures of 0 °C and 50 °C. This model uses a Euro card and comes with a 32-pole multipoint connector that is in accordance with DIN 41612’s design D. The amplifier has an operating voltage of 24 VDC and has an upper limit value of 35 V and a lower limit value of 22 V. The system has a maximum power consumption of 50 VA and its maximum current consumption is 1.8 A. This model has a fuse of 2.5 A and comes with two inputs for inserting command values in the system.
