1756-IH16I: Digital Isolated Input Module
The 1756-IH16I is the Digital Isolated Input Module covered on this page. The attribute that decides whether it fits the existing installation without modification is 125 Volts DC Sink-Source.
On this unit digital isolated input module is the figure that decides fit and function. A processor or controller is selected on memory, scan time and platform compatibility before anything else. digital isolated input module sets how much programme fits, how fast the logic executes and which I/O and networks the unit can host — the three things that decide whether an existing application migrates without a rewrite. Confirming 125 Volts DC Sink-Source against the installed controller family is the check that prevents a processor that boots but cannot run the existing project.
