Product Description:
The EEA-PAM-523-D-32 is a power amplifier with integrated PID modules that is designed for precise control in hydraulic systems. This model is manufactured by Vickers. Vickers has a rich history in producing a wide range of industrial automation and defense products including power amplifiers, hydraulic components, and control systems.
This EEA-PAM-5**-D-32 power amplifiers series unit operates with a nominal 24 V DC power supply and includes reverse polarity protection. It provides control output supplies of + 15 V that are specifically for Linear Variable Differential Transformers (LVDTs). The reference voltages of this model are set at + 10 V and – 10 V each capable of delivering up to 5 mA. This module accepts command inputs in both voltage and current forms. The voltage command inputs have a range of ± 10 V with an input impedance of 47 kΩ while the current command inputs support a range of ± 20 mA with an input impedance of 100 Ω. A feed forward input is available that features an input impedance of 6 kΩ and a voltage range of ± 10 V.
This amplifier includes an input to the ramp generator which has an input impedance of 10 kΩ and accepts voltages ranging from ± 10 V. Sensor inputs of this unit are designed to accommodate both voltage and current signals. For voltage inputs, the impedance is 1 MΩ and supports ranges of 0 to 10 V or ± 10V. Current inputs are also supported with an impedance of 100 Ω and ranges of 4 - 20 mA or 0 - 20 mA. This power amplifier is equipped to monitor sensor failures particularly for sensors with current outputs. The amplifier's design ensures all outputs are short circuit protected.
