A Power amplifier is an essential component for the precise control of proportional valves, especially in applications that require flexible adjustment and high reliability. This compact and inexpensive amplifier has been specially developed for controlling directional control valves with two solenoids and offers a wide range of functions that make it indispensable for numerous industrial applications.

Compact design with easy installation

The power amplifier is housed in a Type A plug housing in accordance with DIN EN 175 301-803 and is mounted directly on the valve. With a M12 cable connection and a second valve connector connected to the amplifier via a cable, easy integration into existing systems is guaranteed.

Flexible input signals and independent output current control +/- 0…10 V or optionally 4…20 mA A particular advantage is the regulated output current, which operates reliably regardless of the supply voltage or magnetic resistance.

Easy to configure – locally or via PC

The power amplifier is parameterized via a Integrated USB Type Mini 2.0 port or using a programming adapter (ULA-310). Alternatively, the LIN bus can be used. With the WPC-Software All important parameters such as RAMP, MIN/MAX, output current, and DITHER (frequency and amplitude) can be set intuitively.

Security and surveillance functions

The short-circuit-proof output stage monitors for cable breaks and automatically switches off the power output stage in the event of a fault. This increases operational safety, especially in critical applications.

Customizable characteristics and linearization

One highlight is the option to Valve characteristic curve over up to 21 XY points to linearize. This allows, for example, a linear response between the input signal and the output pressure to be achieved in pressure valves. The result is precise and reproducible control.

Typical applications and compatibility

The power amplifier is ideal for controlling Directional control valves with flexible adjustment requirements. It is compatible with proportional valves from various manufacturers, such as BOSCH REXROTH, BUCHER, DUPLOMATIC or PARKER compatible, making it versatile.
