New Silicon Labs’ High-Speed Multi-Channel PLC Input Isolators

At the core of stakes, we have: a purpose-built solution for PLC applications including industrial I/O modules, computer numerical control (CNC) machines and servo motor control, and automation controllers (PACs) used in distributed process control systems. 

In effect, the new Si838x digital isolators from SiliconLabs are integrated single-chip devices providing eight channels of 24 V digital field interface. This level of integration can enable developers to create PLCs with up to 128 channels supported by a single serial peripheral interface (SPI) port on the system’s embedded processor. 

The newSi838x PLC can meet the demands of programmable logic controller (PLC) applications.
