The Action Pak AP4081 is a bridge or strain-gauge input signal conditioner with 1500VDC isolation between input, output and power. The field configurable input and output offer flexible, wide ranging capability for bridge or strain-gauge input applications from 0.5mV/V to over 50mV/V.

Wide ranging, precision zero and span pots allow 50% adjustablity of offset and gain within each of the 11 switch selectable input ranges. The output can be set for either 0-5V, 0-10V, 0-1mA or 4-20mA.

This flexibility, combined with an adjustable (1 to 10VDC) bridge excitation source, provides the user a reliable, accurate instrument to isolate and condition virtually any bridge or strain-gauge input.
