Product Description:
The EEA-PAM-535-D-32 is an electrohydraulic power amplifier card manufactured by Vickers for the EEA-PAM Power Amplifiers series. Mounted in a valve stack or control cabinet, the board converts low-level electrical references from a PLC into proportional coil drive signals, letting industrial machinery regulate fluid flow or pressure with closed-loop accuracy. It forms the intermediate stage between automation controllers and servo-controlled directional or pressure valves, ensuring that commanded motion profiles are reproduced by the hydraulic actuator without oscillation.
Protective functions are built in: the alarm circuit can sink or source up to 50 mA through a series resistance of 50 Ω, enabling direct coupling to indicator lamps or control relays. Motion references may arrive as a current within ±20 mA or, alternatively, as a voltage inside ±10 V; the board scales either signal to the spool-drive stage with identical gain. A regulated auxiliary rail of +15 V is provided on the front connector so external potentiometers or low-power sensors can be energized without a separate supply. These ranges let the amplifier accept both differential current loop outputs and standard ±10 V analog cards used in modern programmable controllers.
Signal integrity is maintained by defined impedances at each terminal. The current command input presents 100 Ω, while the feed-forward node exhibits 6 kΩ and accepts a supplementary ±10 V profile for open-loop biasing. Diagnostic monitoring is available through a test pin that carries 10 kΩ impedance and reproduces the drive level across a ±10 V span. Ramp shaping shares the same 10 kΩ loading and ±10 V limit, allowing controlled acceleration and deceleration. The card also furnishes internal references of -10 V and +10 V, each able to deliver 5 mA for external summing networks. High-impedance measurement channels are supported by a sensor input rated at 1 MΩ, while the general voltage input path shows 47 kΩ to minimize loading on upstream sources.
