Product Description:
Bosch Rexroth Indramat's VT-MSPA 1-508-10/V0 is an Analog Amplifier for operating pressure valves without electrical feedback. To get a linear command value pressure characteristic, it uses a conventional command value signal between 0 and +10 V that is changed in the characteristic curve generator. To provide accurate current control, the power output stage creates a pulse width modulation (PWM) signal using the control output and clock frequency.
The rated solenoid current of the VT-MSPA 1-508-10/V0 analog amplifier can be adjusted with the trimmer. Adjusting the zero-point offset with the zero-point potentiometer guarantees precise functioning. The control output inclination can be limited by an inbuilt ramp generator. The trimmer is used to set the time for the command value voltage to decrease. One feature of the amplifier is a clock generator that adjusts the output stage's frequency. The green "ready for operation" light will go out if there's a problem. The analog amplifier is compatible with pressure valves that require precision control, such as DBET-6X and DBEM...7X, and enables industrial automation applications. The amplifier offers basic protection in controlled situations with its IP20 protection class, as per EN 60529. Regardless of the weather, you can rely on the amplifier's dependable operation because of its storage temperature range of -25 to +85 °C.
With an operating temperature range of 0 to +50 °C, the VT-MSPA 1-508-10/V0 analog amplifier is capable of functioning in a variety of operational environments. The frequency of the clock generator can be adjusted to suit the needs of the system. To guarantee steady operation, the power output stage compares the current flowing through the solenoid to the output of the current controller. The amplifier satisfies the needs of industrial automation by providing accurate and dependable control of pressure valves.
Frequently Asked Questions about VT-MSPA 1-508-10/V0:
Q: Does VT-MSPA 1-508-10/V0 support fault recognition for solenoids?
A: Yes, the amplifier monitors solenoid conductors for cable breaks, short circuits, and over-current. If a fault occurs, the green display turns off.
Q: Why does VT-MSPA 1-508-10/V0 include a zero-point adjustment?
A: The zero-point potentiometer allows correction of offset in the command signal. This ensures accurate pressure control and consistent system response.
Q: How does VT-MSPA 1-508-10/V0 ensure stable solenoid current?
A: The amplifier compares the solenoid current with the control output in the current controller. This ensures stability and prevents fluctuations.
Q: Do VT-MSPA 1-508-10/V0 trimmers adjust command voltage timing?
A: Yes, the trimmer "t" sets the time for decreasing command value voltage. The trimmer "Gw" adjusts the rated solenoid current.
Q: Why does VT-MSPA 1-508-10/V0 have an adjustable clock generator?
A: The clock generator frequency is adjusted based on the command value. This ensures precise timing for pressure valve control.
