The AN203 servo-amplifier has been designed for pressure control circuits with position-controlled pressure valves.

The AN206 controller module has been developed for use in plant engineering. Combination with other modular units permits assembly of any controller arrangements required. The P, I and D components can be adjusted internally or externally, via potentiometers. External parameter adjustment is used predominantly in test and inspection system engineering.

The AN207PC servo-amplifier has been specially designed for pressure control circuits in conjunction with a pressure adjustment valve. Thanks to the use of a PI controller, this module permits high accuracy between the Actual pressure value and the target-value (setpoint) input. The controller is suitable for the majority of applications requiring high linearity, independence from flow, freedom from hysteresis and independence from temperature of the set pressure.

The AN208 setpoint module was designed for the application of setpoints in electrohydraulic open and closed loop control systems. With this module, it is possible to connect external setpoint potentiometers or the setpoints that are adjustable on the module can be connected internally. If external setpoint potentiometers are used, the internal multi-turn resistors can be used to extend their setting range.

The AN209 servo amplifier has been designed to control single-magnet proportional valves and throttle-valves. The module is provided with various setpoint inputs: 4-20mA, 0-20mA, 0-5V, 0-10V, user selectable 10k /V An external enable input allows to lock the amplifier. The ramp gradients can be set separately for rise and fall.

The AN 210 module has been designed as a logical element for systems. The many different OP circuits, solder tags for components and the possibility of external interconnection for the individual OP amplifiers make this module suitable for a wide range of applications.

The AN220 servo amplifier is suitable for controlling the most popular servo valves. The module provides current ranges of -20mA, -100mA, and -400mA for this purpose. The valve modulation can be adjusted by an internal/external limiter. In addition, the module is equipped with a PID controller, allowing a control system with a servo valve to be set up.

The AN 223 measurement socket module has 20 measurement sockets on the front plate. These allow rapid checking of the individual function stages of a system. In addition, 9 pairs of solder tags are provided for use as required.

The AN 230 was especially designed as a amplifier to control proportinal valves without position feedback combined with the possibility to get the command signals direct from the amplifier. Hereby the command signals can be used as fixed values or together with an external potentiometer.

The AN238 servo amplifier has been designed for the control of axial piston pumps valves in conjunction with servo valves. The module can be used as a pressure controller (zero stroke pump) or a volumetric flow controller by changing jumpers.

The AN239 setpoint module permits universal setpoint switching in electro-hydraulic open and closed loop control systems. It has five adjustable setpoints and a polarity reverser. An externally switchable and adjustable ramp is assigned to each setpoint.

The AN 240 converter module has been developed to convert current signals to voltages and voltage signals to currents. A large selection of current and voltage ranges can be set thanks to the extensive input circuitry and simple positioning of jumpers.

The power supply AN 241 is a powerpack unit,which allows to supply installations and systems with 24VDC. The output of the unit are two voltages + 15VDC and 15VDC to supply analogues units. Additional be a auxiliary voltage made available.

The AN527 servo amplifier has been designed for controlled proportional-stroke valves with two magnet coils.

The amplifier AN528 was developed to control proportional valves in a closed-loop control. The AN527 is used as a basic unit. By connecting a special module it is possible to drive the AN527 as the AN528 together with positioning controlled proportional valves.

The AN532 servo amplifier has been designed to control single-magnet proportional valves and throttle valves.

The AN533 servo amplifier has been designed to control single-magnet proportional valves and throttle valves with position controller.

The AN535 servo amplifier has been designed as a low-cost unit for single-magnet proportional valves.
