Product Description:

The EEA-PAM-533-B-21 power amplifier card is produced by Vickers for the EEA-PAM Power Amplifiers series. Installed in a 3U Euro-rack slot, it scales electronic references and drives proportional valve solenoids so that hydraulic axes follow precise flow and pressure commands. By converting low-level control voltages into regulated coil current, the board links PLC outputs to motion in presses, injection machines, and other industrial equipment that depend on repeatable spool positioning.

The amplifier operates from a nominal supply of 24 V DC, and its voltage channel accepts a full-scale reference of 10 V. Current-mode control is also available through a separate input that reads up to 20 mA, while presenting 47 kΩ of impedance to protect sensitive controller cards. When driven to maximum, the onboard stage can deliver 2.7 A to the valve solenoid, ensuring full stroke without external boosters and keeping heat within rated limits.

Slew characteristics are refined by an adjustable ramp that extends transitions to 5 s, minimizing shock to mechanical components. The drive circuit is enabled only after the logic line reaches 9.8 V, preventing unintended motion during power-up. For position feedback, the card supplies a stabilized +15 V rail at 50 mA for an LVDT transducer, and duplicate test points mirror the command, spool, and reference signals at 10 V full scale for diagnostics. Additional features include a 100 Ω current input impedance, a ±10 V reference output, a DIN 41612 F48 edge connector, 330 g mass, and a 50 °C ambient temperature ceiling.
