HI8429 Discrete to Digital Sensor


The HI8429, HI-8429 is an 8-channel discrete-to-digital sensor fabricated with Silicon-on-Insulator (SOI) technology designed to interface with a Serial Peripheral Interface (SPI).
Each input is individually configurable as either GND/Open or Supply/Open (28V/Open). Discrete input thresholds are programmable in the range of 2V to 12V. An SPI bus is used to configure the sensors and to read sensor data .
