There are two types of digital input, differentiated by their power source: isolated and non-isolated. Non-isolated inputs are powered by a common source. For example, the wiring diagram shows a ...

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.

Designers now have a way to reduce power, system cost, and size for programmable logic controller (PLC) digital-input subsystems, with the Corona (MAXREFDES12#) reference design. This design reduces ...
