Product Description:

Bosch Rexroth Indramat manufactured the VT-VRPA2-537-10/V0/RTS electric amplifier for use in industrial automation. Its design prioritizes the efficient control of hydraulic and electrohydraulic systems that rely on precise signal inputs for operation. The amplifier's input tolerance of +40% / -20% and operation on a 24 VDC power source guarantee consistent performance regardless of environmental factors. With its accurate signal measurement and control capabilities, this amplifier is ideal for control applications that are particularly demanding.

For command values, the VT-VRPA2-537-10/V0/RTS amplifier has numerous analog input possibilities. The potentiometer inputs have a resistance of more than 100 kΩ and can receive signals from 0 to ±10 V. With a resistance greater than 50 kΩ and the same voltage range, Command Value 5 operates as a differential input. To make sure it works with different sensors, the Command Value 6 input can handle current signals ranging from 4 to 20 mA and has a load resistance of 100 Ω. In addition to an external ramp time adjustment input that can be adjusted from 0 to +10 V, the amplifier has an internal resistance of 10 kΩ that can be increased to +15 V. The amplifier includes an interchangeable 2 A medium time-lag fuse for further convenience during maintenance.

The VT-VRPA2-537-10/V0/RTS amplifier is a dependable control solution that meets even the most stringent standards thanks to its strong construction. In order to offer accurate voltage feedback, it incorporates measuring sockets and ensures safe operation within the given voltage range. Consistent operation is guaranteed by the amplifier's efficient power-regulating technology. The amplifier keeps running smoothly thanks to its regulated power usage and well-defined operating range. Durability is enhanced by the design's exchangeable protective components.
