Product Description:

The VT-VSPA2-1-21/V0/T5 VT-VSPA Proportional Amplifier is the high proportional amplifier made by the Bosch Rexroth. This model of VT-VSPA Proportional Amplifiers is designed to control different valve types 4WRA6, 4WRA10, 4WRZ, and 3DREP. This amplifier works efficiently on the 24 VDC power supply with a tolerance of +40% to --20 %. The 50A power is consumed and a 2A fuse is utilized for circuit safety.

The VT-VSPA2-1-21/V0/T5 VT-VSPA proportional amplifiers can control different clock frequencies like 300 to 370 Hz for WRA6, 180 to 410 Hz for WRA10 and 170 Hz for both WRZ and 3DREP modules. The 48-pin blade connector of form F type is used for connection purposes. The card dimension of the Eurocard 100 × 160 mm is utilized in this amplifier. Command value 1 to 4 provides a potentiometer input of voltage ranging from 0 to +/-10 V with a resistance of 100kΩ. Command value 5 can control the differential input with 0 to +/-10 V and resistance above 50kΩ. The command value 6 has the current input from 4 to 20mA having a load resistance of 100 ohms. The VT-VSPA Proportional Amplifiers have the controlled voltage output of +/- 10 V with a variance of +/- 2% and the ability to provide up to 25mA. The current output is up to 2.5A.

The VT-VSPA2-1-21/V0/T5 VT-VSPA proportional amplifier have the operational output normally greater than 16V at 50 mA current but will drop below 1V in fault conditions. This model of VT-VSPA Proportional Amplifiers provides the specialized output for command value, actual value and measuring point signals. This output has a voltage of +/- 10V with an accuracy of +/-2% and a maximum current of 2 mA.
