Product Description:
The EEA-PAM-581D32-EN3 is a plug-in power amplifier built by Vickers for the EEA-PAM Power Amplifiers series. In an automation cabinet it converts command references into regulated output so that a proportional solenoid receives the correct drive current for position or force control. By matching its electrical interfaces with common PLC or analog controllers, the card becomes an intermediary element that shapes low-energy control signals into the higher-energy form demanded by field actuators.
The voltage command channel spans ±10 V and is buffered by a high-resistance input of 47 kΩ, limiting the burden on upstream electronics. A current command path is also provided; it tolerates ±20 mA and terminates into a precision sense resistor of 100 Ω, establishing a predictable voltage drop for loop controllers. Internal regulators operate from a logic supply of 24 V DC, allowing the board to reside on the same power bus as other control hardware. These parameters define how the amplifier interprets external references and ensure consistent scaling between the user’s command range and the card’s output stage.
The power section can deliver up to 50 W to its output devices while respecting a maximum solenoid load of 3.2 A; this capacity accommodates proportional coils that need sizable magnetizing current during full stroke. At the zero-volt command point the driver idles at 1.7 A, giving a bias that offsets valve dead-band. Diagnostic measurements are available through a monitor jack that presents a non-loading impedance of 10 kΩ, making it safe to connect standard multimeters or data loggers. Together, these limits on power, current and measurement access support predictable operation when the amplifier is integrated into closed-loop hydraulic or pneumatic control schemes.
