Power Amplifier: Features and Benefits

A power amplifier is essential for the precise control of proportional valves, particularly in applications requiring high reliability and flexible adjustments. This compact and cost-effective amplifier is specifically designed for directional valves with two solenoids and is suitable for numerous industrial applications.

Compact Design and Easy Integration
The device is housed in a DIN EN 175 301-803 connector and mounted directly onto the valve. An M12 cable connection and an additional valve connector enable quick and seamless integration into existing systems.

Flexibility and Current Regulation
It supports input signals such as +/- 0…10 V or 4…20 mA. The regulated output current (up to 2.6 A) operates reliably, regardless of supply voltage or coil resistance.

Easy Configuration
The amplifier can be configured via USB Type Mini 2.0, LIN bus, or a programming adapter (ULA-310). The WPC software allows intuitive adjustment of key parameters such as RAMP, MIN/MAX, output current, and DITHER.

Safety and Monitoring Features
The short-circuit-proof output stage monitors for wire breaks and automatically shuts down in case of errors. This enhances operational safety, even in critical applications.

Characteristic Curve Adjustment
The valve characteristic curve can be linearized with up to 21 XY points, ensuring a linear relationship between input signal and output pressure, for example, in pressure valves.

Versatile Applications
The amplifier is compatible with proportional valves from manufacturers such as BOSCH REXROTH, BUCHER, DUPLOMATIC, and PARKER, making it highly versatile.

Conclusion
With its compact design, flexible configuration options, and high compatibility, the power amplifier is an efficient solution for the precise control of proportional valves in industrial applications.
