DescriptionRexroth Bosch Model VT-3000 Valve Amplifier Card | for Proportional Directional Valves and Proportional Pressure ValvesWith the command value inputs 1 to 4 command values can be called up [1] by operating the corresponding relays (K1 to K4). The command value voltage is either given directly through the controlled voltages ± 9 V of the power supply [10] or via an external command value potentiometer. For this inputs ± 9 V = ± 100 % 1) is valid. If these four command value inputs are directly connected to the controlled voltages ± 9 V four different command values can be set at the potentiometers "R1" to "R4". When using external command value potentiometers at these inputs the internal potentiometers also function as weakeners or limiters when these are not set to maximum.
Key FeaturesSuitable for the control of pilot operated proportional directional valves (type .WRZ, up to series 6X) and direct operated pro por tio nal pressure valves (type DBEP6 and 3DREP6, each series 1X) without electrical position feedback– Four command values adjustable with potentiometers– Four command value call-ups with LED display– Differential input– Step function generator– Ramp generator– Two pulsed current output stages– Polarity protection for the voltage supply
