EEA-PAM-581-D-32

EEA-PAM-581-D-32 is a Vickers unit in the EEA-PAM Power Amplifiers series. It operates from a 24 VDC supply and provides a +15 VDC control-supply output for compatible control circuitry. Its command-voltage input has an impedance of 47 kΩ, while the current-command input has an impedance of 100 Ω. The feed-forward input impedance is 6 kΩ, and the ramp-generator input impedance is 10 kΩ; these values establish the electrical loading presented to connected command and ramp signals.

The sensor-voltage input has an impedance of 1 MΩ for voltage-based feedback, while the sensor-current input has an impedance of 100 Ω for current-based feedback. The monitor point has an impedance of 10 kΩ for connection to monitoring equipment. The +10 V and −10 V reference outputs each support 5 mA, providing bipolar reference signals for external circuits.

The alarm output supports a maximum current of 50 mA and has an output resistance of 50 Ω. The drive-zero output also has a resistance of 50 Ω, setting its output characteristic when transmitting the drive-zero signal. The ramp-active output has a resistance of 10 kΩ for indicating ramp-generator activity to connected control equipment.
