Product Description:
The EEA-PAM-535-B-32 is a plug-in power amplifier card manufactured by Vickers for the EEA-PAM Power Amplifiers series. Mounted on a backplane, the card drives the armature coils of a proportional directional valve, specifically the K*G4V-5, so spool displacement follows an external command signal. Within an industrial automation loop it converts control room references into field-level hydraulic motion, linking a PLC’s low-power output to the energy handled by the valve solenoids.
The module accepts two alternative command formats: a current reference of ±20 mA or a voltage reference of ±10 V. The current channel presents a load of 100 Ω, while the voltage channel is buffered by 47 kΩ; these impedances let the user match source capabilities without signal distortion. A ramp generator is available through a 10 kΩ input so slew rates can be shaped independently of the command source. Drive logic is gated—output is disabled below 4.5 V and is enabled once 9.8 V is exceeded—which allows interlocking with external safety relays. The amplifier runs from a nominal bus of 24 VDC; if that supply falls below the 18 VDC shutdown threshold the card disconnects the valve to prevent partial actuation. All connections are made through a DIN 41612 F48 edge connector, and a ±10 V, 5 mA reference is provided for feedback devices.
A local command voltage source supplies +10 V, 10 mA to power potentiometer sets, while a dedicated control rail of +15 V feeds auxiliary electronics such as LVDT feedback cards. The output stage can deliver up to 2.7 A of solenoid current, giving full stroke capability for the matched valve under steady-state operation. Overall consumption of the board does not exceed 50 W, permitting installation in densely populated racks without overloading cabinet power budgets or thermal management provisions.
