The VT-VSPA2-1-1X-T1-002 is an electrical amplifier introduced by Bosch Rexroth, specifically designed to control direct-operated proportional directional control valves that lack electrical position feedback. This amplifier model is characterized by its single ramp time adjustable amplifier card and an incorporated step function generator. Operating on a nominal voltage of 24V DC, it is built with four adjustable potentiometer command values and can initiate four command value call-ups. The amplifier utilizes a 32-pin male connector adapted for DIN 41612, form D, and is equipped with dual clocked current output stages. Weighing just 0.31 kg, the VT-VSPA2-1-1X-T1-002 exhibits consumption parameters of less than 50 VA power and less than 2A current. The model also includes reverse polarity protection, a standard rack installation option, and an LED indicator system that shows its operating status and aids fault diagnosis. Provisioned as a printed circuit board with dimensions 100mm by 160mm, this device can endure an operational temperature range of 0-50°C and storage temperatures between -25 and +85°C.
