Product Description:

The VT-VSPA2-1-11a/T1 VT-VSPA Proportional Amplifier that is designed and manufactured by the Bosch Rexroth. This model of VT VSPA2 proportional amplifier is a high-precision device with a variety of different input options with command value inputs from 1 to 4 operating at +/- 9V. Input 6 ranges from 0 to +/-10 V and input 5 operates on the +/- 6V.

The VT-VSPA2-1-11a/T1 VT-VSPA proportional amplifier utilizes a 32-pin male connector that conforms to the DIN 41612 standard for secure and reliable connectivity. The amplifier has the Euro card dimension of 100 x 160mm and consumes less than 50 VA of power for efficient power management. Its specific operating voltage is 24 VDC with the variance of +40% to -5%. This proportional amplifier supports a biasing current of 50 mA with a tolerance of +/- 25%. The VT-VSPA2-1-11a/ T1 has a storage temperature range from 25 to 85 °C and an operating temperature range of 0 to 50 °C. A fuse of 3.5 A is installed to protect the device from overcurrent. The relay-releasing voltage is 2.4V and the response voltage is 16.8V, respectively. The Proportional amplifier has the ramp time setting range from 30 ms up to either 1 or 5 seconds. The VT-VSPA Proportional amplifiers have upper and lower voltage limits at 35 V and 22 V.

The VT-VSPA2-1-11a/T1 VT-VSPA proportional amplifier has a lock pulse frequency that can vary with the size of the valve. The size 6 valve offers 300 Hz and the size 10 offers 180 Hz. This model of VT-VSPA Proportional amplifiers weighs 0.13 kg and keeps its current consumption of 2A. The amplifier has an output solenoid current of 2.5A with a resistance of 2 ohms and the relay coil resistance of 2150 ohms.
