Product Description:
The EEA-PAM-513-D-32 is a plug-in power amplifier card manufactured by Vickers for the EEA-PAM Power Amplifiers series. It installs in a Eurocard rack and conditions command signals so proportional hydraulic valves respond with precise spool positioning, a key requirement for repeatable pressure and flow regulation in industrial automation.
The card accepts a differential command of ±10 V or a current reference of ±20 mA, each routed through separate conditioning networks. An alarm circuit presents a load of 50 Ω so external fault indicators can be driven without adding excessive current draw. Physical depth is 175.24 mm, leaving clearances for rear connectors, while the voltage input stage exhibits 47 kΩ impedance to minimize loading on upstream controllers. The current command path sees 100 Ω of input resistance, matching common PLC analog outputs. A ramp generator node is available and is buffered by 10 kΩ impedance so that user-supplied capacitors can shape acceleration profiles without destabilizing the loop. Additional terminations include a 6 kΩ feed-forward input, a monitor test point at 10 kΩ, and matching 10 kΩ resistance on the ramp-active output.
The control section sources +15 V for the valve coil driver, and sensor feedback lines encounter 1 MΩ impedance, preventing measurable loading on position transducers. A stabilized reference of +10 V × 5 mA is provided for external potentiometers, complemented by a –10 V mirror output of the same drive capability. Enclosure dimensions are completed by a card height of 128.4 mm and a width of 100 mm, allowing installation beside adjacent modules without interference. For diagnostic pacing, both the ramp-generator input and the ramp-active return share 10 kΩ paths, while the feed-forward network’s 6 kΩ resistor lets operators superimpose open-loop bias during tuning.
