Product Description
The EEA-PAM-513-A-30 Power Amplifier is designed and manufactured by Eaton Vickers. This model is an advanced device used for driving proportional valves in hydraulic systems. It is designed to control hydraulic actuators in various industrial automation applications, such as in manufacturing, automation, and heavy machinery sectors where precise control of flow or pressure is required.
The EEA-PAM-513-A-30 Power Amplifier operates within a supply voltage range of 17 to 40 V with a PID-controller enable voltage from 17 V to 40 V when enabled and 0 V to 3.5 V when disabled. It includes both digital and analog outputs, such as sensor failure detection and feedback signal outputs. The PID-controller output is provided through pin d4, while error signals and feedback signals are communicated through pins d22 and d24, respectively. The amplifier also provides alarm outputs for drive status through pin z12. This offering a high or low signal based on the operational status of the drive output. The drive signal zero indicator provides a signal to show when the drive is active or within deadband limits. Tt has multiple monitor points like MP1 to MP6 which display vital signals including command and feedback signals.
The EEA-PAM-513-A-30 model includes a feed-forward input with an impedance of 6 k? and a voltage range of ~ 10 V. The input to the ramp generator, used for smooth transitions in the control process, features a 10 k? impedance and the same voltage range of ~ 10 V. The PID-controller's analog output can manage a load impedance greater than 10 k?. The device monitors LVDT (Linear Variable Differential Transformer) positions, which provide feedback for precise control over hydraulic movements. The ambient conditions of the amplifier allow for operation in temperatures ranging from -25 degrees C to 85 degrees C for storage and 0 degrees C to 50 degrees C during operation.
