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 commonly used for industrial applications. These channels can either sink or source current and feature 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 technolog.

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 commonly used for industrial applications. These channels can either sink or source current and feature 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 from the Si838x device allows for low power operation with 2.25 V compliance. These products utilize Silicon Labs' proprietary CMOS-based isolation technology, supporting up to 2.5 kVRMS withstand voltage. This technology enables high CMTI (up to 300 kV/μs), lower propagation delays and channel skew, reduced variation with temperature and age, and tighter part-to-part matching. The Si838x offers longer service life and dramatically higher reliability compared to opto-coupled input solutions. Product options include parallel or serialized outputs. Parallel outputs can be purchased with built-in, low-pass filters for improved noise immunity, reduced design complexity and cost. Cascading a total of 128 channels (16x Si838x) with a single MCU interface is possible with the Si8380S serial output option. The Si8380S also unlocks the ability to configure each channel with unique filtering behavior.
