EEA-PAM-553-D-32

EEA-PAM-553-D-32 is a Vickers amplifier in the EEA-PAM Power Amplifiers series. Its card height follows the 3U standard for installation in compatible card racks, and its overall length is 175.24 mm. A DIN 41612 F48 male connector provides the electrical interface to the host system. The front-panel socket has a diameter of 2.0 mm, allowing connection of compatible test or measurement leads.

The voltage command input has an impedance of 47 kΩ, while the current command input has an impedance of 100 Ω; these inputs receive the respective external command signals. The feed-forward input has a 6 kΩ impedance for accepting a signal that anticipates required system response. The ramp-generator input has a 10 kΩ impedance for receiving commands with controlled transition rates. The sensor-voltage input has a 1 MΩ impedance to minimize loading on the connected sensor, and the monitor point has a 10 kΩ impedance for external signal measurement. Each digital input draws a 10 mA load current when active.

The LVDT supply output provides +15 VDC to power a compatible position sensor. Positive and negative reference-voltage outputs provide +10 VDC and -10 VDC respectively, with each output rated for 5 mA, supporting external command and reference circuits. The alarm output supports a maximum current of 50 mA for connected indication or control equipment. Its output resistance is 50 Ω, which establishes the alarm signal’s source resistance.
