Bosch Rexroth VT-VSPA2-1-2X/V0/T Valve Amplifier


Bosch Rexroth VT-VSPA2-1-2X/V0/T amplifiers are used to control proportional directional valves and proportional pressure valves without electrical position feedback. The command values are pre-set via a differential input or via four callable, adjustable inputs. The step function ensures fast passing of the overlap in directional valve. The two amplifier outputs supply current-controlled signals.

Other features of the Bosch Rexroth VT-VSPA2-1-2X/V0/T valve amplifier include:

  • Differential inputs for voltage and current
  • Four callable command value inputs, input for ramp time
  • Digital inputs for enable, ramp, inverting and command value call-up
  • Model T5 with 5 ramps and quadrant recognition
  • Adjustable ramp times, step level and maximum solenoid current
  • Reverse polarity protection for the operating voltage
  • Switchable measuring socket with version T5
  • “Ready for operation” output
  • Power supply unit with DC/DC converter without raised zero point
