Product Description:

The Vickers made the EEA-PAM-523-F-30, a high-performance amplifier card designed for precise flow control in tough industrial settings. The amplifier card meets strict standards and is a good choice for systems that need to be accurate and last a long time. The EEA-PAM-523-F-30 is compatible with industrial automation systems, to provide consistent functionality and installation flexibility.

The highest pressure that the EEA-PAM-523-F-30 amplifier card can handle is 350 bar (5000 psi), and the highest pressure that can be applied to the tank line is 210 bar (3000 psi). The card can work with either 12V DC or 24V DC coil voltage. The coil inductance at 1000 Hz is 4 mH for type G and 20 mH for type H. When the temperature is 20°C, the resistance of the type G coil is 1.55 Ohms and the resistance of the type H coil is 7.3 Ohms. At 50°C, the highest current for type G is 3.5A, and for type H is 1.6A. The amplifier card works with fluids with a viscosity range of 16 to 54 (75 to 250 SUS) and can handle temperatures from -4°F to 180°F. The amplifier card fits into existing systems easily because its mounting pattern works with ISO-4401-AB-03-4-A, NFPA D03, and CETOP 3 standards. It takes 25 ms for the EEA-PAM-523-F-30 to respond from 0 to 100% and 30 ms from 100% to 0%.

With its IEC 144 Class IP65 electrical protection, the amplifier card is sure to work well in safe environments. With its standard rates and ability to handle the highest tank line pressure, the EEA-PAM-523-F-30 can be used for a wide range of flow control tasks. Wake Industrial guarantees help and availability all over the world for the amplifier card with an international shipping policy and a warranty that covers replacements for one year.
