Product Description:
The VT-VRPA1-527-20/V0/2/2V is an Electric amplifier made to manage directional control valves that are handled by a pilot and have electrical position feedback. This amplifier is made by Bosch Rexroth Indramat. This amplifier is ideal for hydraulic components and fits in standard 19" racks.
The VT-VRPA1-527-20/V0/2/2V electric amplifier needs a 24V DC supply power to work. The amplifier can work with battery voltages between 21V and 40V. The amplifier has outputs that can't short circuit and can tell when a cable has been broken for the real value cable. A PID method is used by the amplifier to give precise position control. This electric amplifier includes a ramp feature. You can turn off this function or use differential inputs to control it from outside the device. The electric amplifier is intended to work with valves that provide electrical feedback. The 2X component series number stands for types 20 through 29. This means that the technical standards are stable and that the pin assignments are always the same. It's made to fit NG 6 pilot control valves. Analog controls are used for the compressor.
This amplifier has a maximum current value of 2.7A and was designed to work with 4WRL directional control valves. The VT-VRPA1-527-20/V0/2/2V amplifier's ramp function allows to change the ramp by controlling the voltage from the outside. The real value signal works at ±10V. The amplifier has an open collection output that goes to +UB. This can hold up to 100mA at most. There are no short circuits in the outputs. It works great for valves that have electrical feedback systems built in. This amplifier is commonly used in industrial automation devices as this is highly reliable.
Frequently Asked Questions about VT-VRPA1-527-20/V0/2/2V:
Q: How does VT-VRPA1-527-20/V0/2/2V use the ramp function practically?
A: The ramp function can be switched off or controlled externally. It uses differential inputs for external voltage-controlled ramp setting.
Q: Why is the VT-VRPA1-527-20/V0/2/2V series numbered from 20 to 29?
A: The 2X series indicates component series 20 to 29. This means there are unchanged technical data and pin assignments.
Q: Does VT-VRPA1-527-20/V0/2/2V support external command value potentiometer?
A: Yes, the voltages +9 V and –9 V are fed to the connector strip. These can be used externally for a command value potentiometer.
Q: Why VT-VRPA1-527-20/V0/2/2V has short-circuit-proof outputs included in design?
A: Short-circuit-proof outputs protect the amplifier from current overloads. This design increases the reliability and lifespan of the unit.
Q: How much current VT-VRPA1-527-20/V0/2/2V can handle for valve solenoid?
A: The amplifier can handle a maximum of 2.7A for the valve solenoid. It supports pilot control valve size 6.
