ISO121x Isolated Digital Input Receivers

Texas Instruments ISO121x Isolated Digital Input Receivers are isolated 24V to 60V digital input receivers, compliant with IEC 61131-2 Type 1, 2, and 3 characteristics. These devices are suitable for programmable logic controllers (PLCs) and motor-control digital input modules. Unlike traditional optocoupler solutions with discrete, imprecise current limiting circuitry, the ISO121x devices provide a simple, low-power solution with an accurate current limit. This feature allows for the design of compact and high-density I/O modules. These devices do not require a field-side power supply and are configurable as sourcing or sinking inputs.
