Maxim Integrated MAX22199 Octal Industrial Digital Input translates eight 24V current-sinking industrial inputs to a serialized SPI compatible output that interfaces with 3V to 5.5V logic. The IEC 61131-2 compliant industrial digital input device operates as eight Type 1/Type 3 digital inputs or four Type 2 digital inputs. The Maxim MAX22199 Octal Industrial Digital Input features diagnostic functions, including thermal shutdown, 24V under voltage alarm, 24V missing voltage alarm, and SPI and CRC communication error detection. All of the faults offer the configuration to generate an interrupt using the FAULT pin.
