Two process control signaling schemes were to be supported — the 0 to 10 VDC analog signal, and the venerable 4-20 mA current loop.

Figure 2 This simple current source (Simple Source) circuit provides accuracy with a single resistor by floating the power supplies of the output stage. Isolated dual output DC to DC converters are ...

The circuit shown is a simple current limiter and is recommended since it offers a higher efficiency than other transistor circuits. It works to limit the current through R_sense such that the ...

A signal-injection circuit for control-loop analysis is flat from dc to 200 kHz, isolated from chassis ground and easily constructed with a readily available instrumentation amplifier ...

Over long cable runs, an isolated 4-to-20-mA current loop offers robust noise immunity and tolerance. This characteristic makes it popular for analog data transmission in noisy ...
