The MAX22190ATJ+ is an IEC 61131-2 compliant industrial digital input device. The MAX22190ATJ+ converts eight, 24V sinking industrial inputs to serialized SPI-compatible outputs that interface with 3V to 5.5V logic. A current-setting resistor allows the MAX22190 to be configured as a Type 1, Type 2, or Type 3 input. The venue verifies the wiring of the proximity switches by a second threshold detector on each input. When wire-break is enabled, the FAULT output is asserted and the register sets the flag threshold if the input current falls below the break-out threshold for more than 20ms. Additional diagnostics asserted on the FAULT pin include: over temperature, low 24V.
