Figure 4: Basic System Level Diagram of an isolated 8-Channel Digital Input Module. Industrial input designs, however, require input resistors for several reasons. For a given current limit, the ...

Let’s take a closer look at the hardware and software. Figure 3. Diagram of the digital-input subsystem reference design. Here U1 is the MAX31911 octal translator/serializer and U3 is the MAX14850 ...

Analog-to-digital converters can pose an especially difficult challenge in this regard, offering a variety of different input sampling architectures that must be considered on the system level.
