Silicon Labs Si834x Isolated Smart Switches are ideal for driving resistive and inductive loads like solenoids, relays, and lamps commonly found in industrial control systems like programmable logic controllers (PLC). The Si834x Isolated Smart Switches are galvanically isolated for safety using CMOS based isolation technology, resulting in better reliability, performance, and high common-mode transient immunity (CMTI) of over 150kV/μs.
