Analog Devices / Maxim Integrated MAX22193 Quad Industrial Digital Inputs

Analog Devices MAX22193 Quad Industrial Digital Inputs translate four 24V industrial digital inputs to four CMOS-logic-compatible, parallel outputs. The propagation delay from input to output is less than 300ns for all four channels. Current-limiter on each digital input significantly reduces power dissipation compared to traditional resistive input. The accuracy of these Analog Devices current limiters minimizes power dissipation while ensuring compliance with the IEC 61131-2 standard.
