Product Description:
The EEA-PAM-535-B-30 is a plug-in power amplifier card produced by Vickers for the EEA-PAM Power Amplifiers series. It conditions low-level command signals and drives proportional valve solenoids, enabling accurate pressure or flow control in industrial automation loops. By locating this module inside a cabinet, designers isolate the hydraulic control electronics from harsh plant environments while coordinating valve performance with PLC-issued references.
Primary energy reaches the board at 24 VDC, and the circuitry consumes a nominal 40 W; enclosure airflow therefore must remove that heat. Inside the card, a regulated rail of ±15 VDC is available and can source up to 50 mA for external signal conditioning. The enable terminal presents 22 kΩ of resistance so upstream logic drivers are not overloaded. Control-supply ripple may not exceed 10 % peak-to-peak, and reverse polarity protection blocks damage if the supply is wired incorrectly. For safe operation the unit rejects control potentiometers below 2000 Ω and reference potentiometers below 4000 Ω, keeping source currents within rated limits.
The reference generator holds ripple to 50 mV (pk-pk), delivers ±10 V at up to 5 mA, and limits temperature drift to 1 mV / °C; its nominal output tolerance remains within ±10 VDC at ±1%. A separate measurement node allows technicians to verify those levels without breaking circuit continuity. Should the incoming supply sag to 18 VDC, an undervoltage detector disables the amplifier to prevent partial coil energization. Together, low ripple, strict accuracy, and automatic shutdown ensure stable hydraulic response even when plant power quality fluctuates.
