Product Information

Back to top
The Si838x provides eight channels for 24 V digital field interface to either sinking or sourcing inputs with integrated safety rated isolation. In combination with a few external components, this provides compliance 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 to the controller allows for low power operation with 2.25 V operation capability. These products utilize Silicon Laboratories' proprietary silicon isolation technology, supporting up to 2.5 kVRMS withstand voltage. This technology enables high CMTI (50 kV/μs), lower prop delays and skew, reduced variation with temperature and age, and tighter part-to-part matching.
