Product Description

Eaton Vickers is a global leader in industrial hydraulics. The company designs power amplifiers to regulate hydraulic systems. Their EEA-PAM-581-D-33 is a power amplifier for precise control of servo or proportional valves, often used in industrial applications. It provides reliable signal conversion that makes it a valuable component for machine control.

The EEA-PAM-581-D-33 power amplifier offers multiple control inputs including direct voltage (~ 10 V) and current input (~ 20 mA), with an input impedance of 47 k? for voltage and 100 ? for current. It supports feed-forward and ramp generator inputs, each with specific impedance and voltage ranges. Sensor input options include voltage (0 to 10 V or ~ 10 V) and current (4 - 20 mA), with appropriate input impedance and sensor failure monitoring. PID-controller enable is managed with a signal range of 17 - 40 V for enabling and 0 - 3.5V for disabling drawing less than 10 mA current. The digital outputs for sensor failure and feedback signals are available that are designed to handle continuous short-circuit conditions with a load current of less than 100 mA. The D series power amplifier also supports LVDT position monitoring, with voltage output monitored at ~10V and an impedance of 10 k?.

The EEA-PAM-581-D-33 power amplifier offers a variety of analog outputs such as the PID-controller and error signals, both operating with a load impedance greater than 10 k? and a ~ 10 V range. Feedback signals from sensors are short-circuit-proof. The product operates in temperatures ranging from 0 degrees C to 50 degrees C, with a storage capability extending from -25 degrees C to +85 degrees C. It features a range of monitoring points, including signals for command, feedback, and LVDT (Linear Variable Differential Transformer) spool position. The amplifier weighs approximately 0.4 kg.
