The Model 430 is a current output signal conditioner, complete with a true differential input instrumentation amplifier, and a highly stable bridge excitation supply. It is powered from the AC line. The input amplifier incorporates a two pole roll off, 3 Hertz filter to reduce the influence of mechanical noise and power line interference on the input. The unit is encapsulated in an epoxy filled plastic container with through bolt mounting holes and screw terminal barrier strips for easy attachment of all wires.
