A two wire isolated and powered 10-bit data acquisition system is described.
10-bit data acquisition
For reasons of safety or to eliminate error producing ground loops, it is often necessary to provide electrical isolation between measurement points and the microprocessor. Unfortunately, the isolated side of this measurement system must still be provided with power. One alternative is to power the isolated side of the circuit with batteries. This solution works if power consumption is low, environmental conditions are mild and the batteries are easily accessible. If these ...
