Product Description:
The EEA-PAM-581-C-30 is a plug-in card from the EEA-PAM-5**-C-32 Power Amplifiers series manufactured by Vickers for hydraulic servo-valve control loops. Installed in stackable sub-racks, the module conditions command signals and drives proportional valves, allowing PLCs or motion controllers to modulate flow and pressure with repeatable ramp profiles in industrial automation systems.
The card draws a control-supply of 24 V DC and needs only 50 mA from that rail, minimizing load on the cabinet’s low-voltage supply. Internal electronics are referenced to a bipolar auxiliary bus of ±15 V, while input immunity is maintained by accepting a maximum supply ripple of 10% pk–pk. Total consumption is rated at 40 W, so enclosure cooling must dissipate that heat during continuous operation. Four trim potentiometers on the front edge let technicians set independent up-ramp and down-ramp gradients for both positive and negative commands, tailoring valve response to machine dynamics.
For external references the amplifier sources up to 5 mA, and its differential command input spans ±10 V—a range compatible with most motion controllers. The ramp generator can stretch a command transition out to 5 s for gentle acceleration or compress it to a brisk 0.050 s when rapid cylinder positioning is required. Reference ripple remains below 20 mV pk–pk to prevent dithering of the valve spool, and an under-voltage latch disconnects outputs if the supply falls to 18 V DC, protecting actuators from partial strokes.
