First high-speed, multi-channel digital isolators introduced by Silicon Labs,are designed to meet the demands of programmable logic controller (PLC) applications,including industrial I/O modules,CNC machines and servo motor control.
The new Si838x PLC field input isolator family provide a combination of high-speed channels (up to 2 Mbps), exceptional channel integration (up to eight channels per device), bipolar input flexibility, high noise immunity and 2.5k VRMS safety isolation. The Si838x isolators are also ideal for process automation controllers (PACs) used in distributed process control systems.
Silicon Labs’ Si838x isolators are highly integrated single-chip devices providing eight channels of 24 V digital field interface. By “daisy chaining” 16 Si838x isolators in a system design, developers can create PLCs with up to 128 channels supported by a single SPI port on the system’s embedded processor.
