Product Description:

The EEA-PAM-568-B-30 is a plug-in power amplifier card from the EEA-PAM Power Amplifiers series manufactured by Vickers. It converts low-level command signals into controlled current for proportional valve solenoids, acting as the electronic bridge between a machine controller and its hydraulic actuator. By regulating coil energy with closed-loop precision, the module supports accurate pressure and flow control in automated industrial processes.

The card is designed for a nominal bus of 24 V DC and may draw up to 40 W during peak operation. Its output stage can source a maximum of 3.2 A, permitting full-force actuation on most industrial proportional valves. Protective circuitry disconnects the drive if supply falls to 18 V DC, preventing erratic hydraulic movement and coil overheating. For the control electronics, incoming line noise is held to 50 mVpp so that small signal fidelity is maintained.

An internal ramp generator provides motion profiling with settings ranging from 5 s down to 50 ms, allowing operators to tailor valve response to system inertia. The enable input presents a high impedance of 22 kΩ, easing connection to PLC digital outputs while accepting a logic high once the 9.8 V threshold is exceeded. For external command potentiometers, the board supplies a stabilized reference of ±10 V at 5 mA with only 20 mVpp ripple, and the separate voltage input path features 47 kΩ impedance to avoid loading the control source.

Wake Industrial stocks this amplifier card and offers same-day shipping on qualifying orders. A 1-year warranty is included with every purchase to cover parts and workmanship. Quotations issued for the EEA-PAM-568-B-30 remain valid for 30 days, giving maintenance planners time to coordinate approvals.
