Product Description:
The EEA-PAM-535-B-32EN9 is a plug-in power amplifier card produced by Vickers for the EEA-PAM Power Amplifiers series. Installed in a 19-inch rack, the module interfaces between a motion controller and a proportional hydraulic valve. It receives voltage or current commands, conditions them, and drives the valve coil so that the spool position follows the reference signal. Internal excitation for an LVDT position sensor and continuous supply-rail monitoring support closed-loop pressure or flow control in industrial automation systems. The rack-mounted format also keeps the signal-conditioning and valve-driving circuits together within the machine control enclosure.
The command inputs accept either voltage or current signals. The differential voltage input accepts a range of ±10 V, while a separate current channel accommodates up to ±20 mA. The voltage path has an impedance of 47 kΩ, which reduces loading on an upstream PLC analog output. The current path is terminated at 100 Ω to provide the proper input load and internal signal scaling. The card operates from a nominal supply of 24 V DC, allowing connection to common control power supplies in machinery panels. A jumper-selectable onboard command source permits independent operation without an external command signal. This internal source can assist with valve setup and functional checks while keeping the external analog input disconnected.
The power stage is rated for 50 W of continuous dissipation, making it suitable for single-spool proportional valves used in medium-flow hydraulic manifolds. Excitation for an LVDT transducer is provided at +15 V with up to 50 mA, giving the sensor a stable supply while cabinet voltage fluctuates within the permitted operating range. If the incoming rail falls below 18 V DC, the amplifier shuts down to protect its output drivers. Operation resumes automatically after the supply voltage returns to an acceptable level, reducing the need for a separate reset circuit. The card operates reliably at ambient temperatures from 0 °C to 50 °C, which suits temperature-controlled industrial cabinets. Its supply supervision helps prevent unpredictable valve commands during undervoltage conditions, while the dedicated sensor excitation maintains consistent LVDT feedback for the closed control loop.
