Product Description:
Bosch Rexroth Indramat made the VT-VRPA2-1-11/V0/T1 as a high-performance analog control amplifier for use in industrial automation. From the 1X line of parts, this one is in the shape of a Euro card.
The VT-VRPA2-1-11/V0/T1 analog control amplifier has several command value inputs, such as potentiometer inputs (w1 to w4) that can handle 0 to ±10V and have a resistance of more than 100 kΩ. It also has a differential input (w5) and a current input (w6) that can handle 4 to 20mA and a 100Ω load resistance. With a voltage range of 0 to +10V and a resistance of 10 kΩ, the product can be controlled by an external ramp time. The enable input makes sure that the process is controlled by turning on at 8.5V to UB and turning off between 0V and 6.5V. There is a command value output and an actual value output, both of which are output signals. Both have an accuracy of ±2%. The result of the measurement signal gives ±10V ± 2% for testing. The power output circuit operates at a clock frequency of around 5 kHz and can handle currents ranging from 0 to 2.5A without short-circuiting. At a frequency of 5.6 kHz ± 10%, the amplifier makes ±5V per output, which makes sure that the system works reliably.
The VT-VRPA2-1-11/V0/T1 analog control amplifier also has a single ramp time choice (T1) that makes it easier to change the controls. The sturdy form of the product ensures that it works reliably in systems that need precise analog control. It was designed to handle 4WRE 6...-2X proportional directional valves. This control amplifier is an important part of making automation processes work well and accurately.
