Si838x Data Sheet Bipolar Digital Field Inputs for PLCs and Industrial I/O Modules The Si838x provides eight input channels ideal for 24 V digital logic monly used for industrial applications. These channels can either sink or source current and feature integrated safety rated isolation. In bination with a few external ponents, this provides pliance to IEC 61131-2 switch types 1, 2, or 3. The input interface is based on Silicon Labs' ground-breaking CMOS based LED emulator technology which enables the bipolar capability (sinking or sourcing inputs) with no VDD required on the field side. The output interface from the Si838x device allows for low power operation with 2.25 V...
