MAX31915 EVALUATION KIT AVAILABLE Industrial, Octal, Digital Input Translator General Description The MAX31915 translates and conditions the 24V digital output of sensors and switches used in industrial, process, and building automation to 5V CMOS-compatible signals required by microcontrollers. It provides the frontend interface circuit of a programmable logic controller (PLC) digital input module. The signal voltage translation is performed in conjunction with input current limiting and lowpass filtering. Input current-limiting allows a significant reduction in power consumed from the field-supply voltage, as compared to traditional discrete resistor-divider implementations.
