AC/DC Input Module
401016
Product Overview
The ac/dc input module provides dc-coupled isolation and scaling for four independent dc or ac voltage or current
channels for the TESLA Power System Recorder. These channels have a bandwidth from dc to 2 kHz but are limited to
1.5 kHz by anti-aliasing inside the recorder. Externally mounted resistors set the input type and full scale range of the
module. The output signals from the module provide isolation and conditioning for the TESLA Power System Recorder’s
analog input channels.
Note:
Locate modules up to 1200 meters (4000 ft) from the recorder.
