Isolated, Wide-Bandwidth Strain Gage Input 5B38 FEATURES Wide-bandwidth Single-Channel Signal Conditioning Interfaces, Amplifies, and Filters signals from full-bridge and half-bridge strain-gage transduces between 300Ω and 10kΩ. Isolated Precision Output of -5V to +5V. 10 kHz bandwidth of the 5B38 ideally suits to measure signals that vary rapidly with time. Module circuitry can withstand 240v rms at the input screwterminals. All 5B38 series modules are mix-and-match and Hot Swappable.
