Product Description
The EEA-PAM-571-D-32 power amplifier is an advanced control unit developed by Vickers. Vickers is renowned for its precision engineered products designed for high performance hydraulic systems. This amplifier is designed to provide precise control and reliable performance for various industrial automation applications.
The EEA-PAM-571-D-32 power amplifier supports a wide range of signal processing functionalities and is equipped with multiple monitoring points for real time diagnostics and performance checks. It features a drive signal zero indicator (b20) and offers a drive signal at null with an output equal to supply minus 1.5 V. During active operation, the output signal is maintained at 0 ± 2 V. The output resistance of 50 Ω contributes to stable signal transmission and compatibility with standard components. This amplifier is integrated with potentiometers for feed forward adjustments ranging from 20 % to 100 % and its proportional gain (P-gain) can be adjusted between 0.1V/V and 50V/V depending on the DIL switch D2 setting. The sensor signal gain ranges from 90 % to 120 % while the offset can be adjusted within a ± 10 % range for fine tuning feedback control.
Monitoring capabilities of this EEA-PAM-5**-D-32 power amplifiers series model are enhanced with six key monitor points: MP1 for the conditioned command signal, MP2 for LVDT (spool) position, MP3 for command signal, MP4 for feedback signal, MP5 for PID controller output and MP6 for integrator output (set at 100 % independent of switches D3, D4, and D5). Each monitor point has an impedance of 10 kΩ that allows efficient signal tracking without significant voltage drops. The amplifier supports a voltage range of ± 10 V for various input and output signal requirements.
