MAX22190 Description
The MAX22190 is an IEC 61131-2 pliant industrial digital input device. The MAX22190 translates eight, 24V current-sinking, industrial inputs to a serialized SPIpatible output that interfaces with 3V to 5.5V logic. A current setting resistor allows the MAX22190 to be configured for Type 1, Type 2, or Type 3 inputs.
