Signal-conditioning module provides two instrumentation amplifiers ideal for low-level signals such as bridge circuits (e.g. strain gauges) and thermocouples. Each amplifier converts a differential input to single-ended. The LJTIA has switches to choose from 5 gain settings (x1, x11, x51, x201, or custom) and two output voltage offsets. The 4-pin design plugs into the standard AIN/AIN/GND/VS screw terminal block found on LabJacks such as the U3, U6, UE9, and T7.
