Internal Product Review
The Vickers EEA-PAM-561-C-31 is a power amplifier with a 24 VDC, 50 W supply and a DIN 41612 F48 male connector for straightforward integration. A 47 kΩ voltage input impedance paired with a ±10 V x 10 mA command source supports stable signal handling and responsive electrohydraulic control. Strong tuning flexibility from the 10% deadband setting makes this unit a highly capable choice for precise system performance.

Product Description:
The EEA-PAM-561-C-31 is a plug-in power amplifier module produced by Vickers within the EEA-PAM Power Amplifiers series. Designed to mount in a DIN 41612 backplane, the card converts low-level command signals into controlled current for proportional solenoid valves used in industrial presses, machine tools, and motion stages. Connection to the rack is made through a DIN 41612 F48 male header. The module is intended for hydraulic control circuits that require stable solenoid drive from low-level analog commands.
Control parameters on the board accommodate both external voltage signals and onboard trimming. A command source of ±10 V at 10 mA can be applied through the front test pins or through the backplane; the signal first encounters an input impedance of 100 Ω, which helps minimize source loading during current-mode control. For voltage-mode operation, an adjustable 5 kΩ command potentiometer establishes a manual set point. The amplifier incorporates a deadband trimmer set at 10% so spool overlap in the valve can be neutralized at zero command. Overall loop sensitivity is factory tuned to 10%/V, allowing a full output span with a one-volt change at the input. Output current is limited electronically to 1.8 A, safeguarding the proportional solenoid, while a quiescent demand of 1.4 A is drawn when the command level rests at 0 V.
Board power is supplied at 24 VDC, 50 W, and the available margin supports rapid current rise without external heat sinks. When the unit is driven with a voltage signal instead of current, a front-end network presents 47 kΩ of input impedance to prevent source loading. The reference output provides ±10 V at 5 mA for remote potentiometers or PLC analog cards. Physical size suits standard Euro-card racks; the height is 128.4 mm, the width is 40.3 mm, and the length is 175.24 mm, so multiple amplifiers can share a narrow control cabinet.
