Product Description:

Bearing the EEA-PAM-541-D-32 designation, this plug-in card is a power amplifier produced by Vickers and belongs to the EEA-PAM Power Amplifiers series. It installs on a rack back-plane and converts low-level electrical references into coil currents that drive proportional hydraulic valves, enabling closed-loop pressure or flow control in automated machinery lines and test stands.

It is powered from a 24 VDC cabinet supply. Two internal reference sources provide +10 V and −10 V at 5 mA for joystick or potentiometer tracking, and the ramp-generator input impedance is 10 kΩ so external capacitors shape acceleration without heavy loading. Command signals are accepted either as a current loop of ±20 mA into a 100 Ω input or as a voltage of ±10 V. A 6 kΩ feed-forward node lets designers linearize valve behavior, while a 10 kΩ monitor point reproduces the drive voltage over the same ±10 V span for oscilloscope checks. Digital enable lines draw only 10 mA, matching standard PLC outputs.

A back-plane connection is made through the DIN 41612 F48 Male plug that mates with standard Eurocard racks. The voltage command path presents 47 kΩ impedance, ensuring minimal burden on analog I/O cards, and the card furnishes a stabilized +15 V control supply for external sensors. Reference voltages of +10 V and −10 V at 5 mA are routed to the front panel alongside the 10 kΩ ramp jack, giving installers consistent sources without extra power modules. Mechanically the module follows the 3U Eurocard outline, standing 128.4 mm high and extending 175.24 mm deep into the enclosure; these dimensions simplify cabinet layout and leave space for airflow between adjacent cards.
