Description
The EATON EEA-PAM-553-A-32 Power Amplifier with PID Modules is a versatile, all-in-one solution designed for precision control of proportional valves and motion systems. It combines a power amplifier with built-in PID functionality, offering five voltage inputs (one inverting) and a 0-20mA current input, with adjustable zero point, deadband compensation, and gain to easily tune to proportional control valves. A switchable ramp function generator further enhances control flexibility, allowing smooth command signal transitions via the “ramp enable” control.

Equipped with user-configurable PID feed-forward and closed-loop operation, this module supports diverse applications including closed-loop pressure, velocity, and position control, as well as p/Q control with internal or external switch-over from flow (Q) to pressure (p). It integrates an analog feedback sensor interface (compatible with LVDTs for spool position monitoring or solenoid current measurement for valves without LVDTs) and front-panel monitor points for convenient measurement of the conditioned command signal (modified by zero, gain, ramp, and compensation settings) and feedback signals.

Built for industrial efficiency, the EEA-PAM-553-A-32 reduces external wiring, saves rack space, and operates on a single 24V DC supply (20-40V DC range, 50W nominal), with reverse-polarity protection and amplifier shut-down below 18V DC. It provides reference voltages (z2: +10V x 5mA; b2: –10V x 5mA) and a dedicated +15V supply (z22) for LVDTs, with analog inputs supporting 4-20mA or 0-20mA current ranges and 47 kΩ voltage input impedance. Configurable via DIL switches (D1-D9) and potentiometers, the module offers easy reconfiguration across different cards, making it a flexible choice for various industrial automation scenarios while inheriting all features of EATON’s “A” series amplifiers (excluding gain).
