AN535 / AN135

Servo Amplifier

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

Applications include the control of proportional pressure control and throttle-valves. The module is provided with various setpoint inputs 4-20mA, 0-20mA, 0-5V, 0-10V, user selectable, 10kΩ/V. The ramp gradients can be set separately for rise and fall.

In addition, Imax, Imin and the dither amplitude can be set via multi-turn resistors. As an option, the module can be supplied with an external input for ramp switch-off. Ihe pin assignments and functions of the AN535 are compatible with the AN135.
