16-channel piezoelectric signal conditioner and power supply
Each channel of the Endevco model 2793 offers constant current excitation, either 4 or 10mA for the transducer or RCC, with all outputs buffered for driving long cables. The signal conditioning unit offers a relatively low per-channel cost and a wide frequency range of 1Hz to 80kHz. LED status indicators inform the user of short, open or normal operating conditions, ensuring greater test setup reliability. For added flexibility, each channel provides gain (1 or 10) and current excitation (4 or 10mA) settings, selectable by internal jumpers. In addition, the model 2793 offers a “D” output connector for simple connection to a D/A board. Designed with a 19-inch rack mount, to be used as a drop-in replacement for legacy or competitive models, the Endevco model 2793 is suitable for the support of general purpose vibration laboratory testing, aerospace and automotive test cells or higher-channel count NVH testing applications.
