Product Description
The model eea-pam-523-a-32 is a power amplifier card designed to control hydraulic solenoid valves. It operates with a maximum solenoid current of 1.6 A and has an amplifier input current of 0.3 A at 0 V command signal (MP1).
The model is powered by a nominal 24V DC power supply with a power output of 50 W, ensuring efficient and stable operation. The voltage range for the power supply is between 20 V and 40 V, with protection against reverse polarity. The signal sources for the EEA-PAM-523 amplifier card include ?15 V and ?10 V options, accommodating a variety of control signals with maximum peak-to-peak ripple specifications of 50 mV and 20 mV, respectively. The card features a deadband compensation adjustment per direction of 0 to 50 % of the maximum spool stroke from the centered position allowing for precise control and minimizing dead zones in valve operation. The model accepts command inputs in both voltage and current forms. It supports direct and inverting voltage inputs ranging from 0 to ?10 V and current inputs from 0 to ?20 mA. The input impedance is set at 47 k for voltage and 100 for current. The EEA-PAM series amplifier card includes factory-set dither and gain adjustments, with a gain adjustment range per direction of 2.5 to 10% per volt.
The card eea-pam-523-a-32 also offers short-circuit protection for all outputs. The model?s temperature drift is minimized to less than 1 mV/?C, ensuring stable performance across a wide operating temperature range of 0 to 50?C (32 to 122?F). The factory setting for ramp-time adjustment is approximately 50 ms, with adjustable ranges from 50 ms to 5 s. Wake Industrial has this product in stock.
