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
