The MikroElektronika DIGI IN 2 Click is a compact add-on board designed for converting high-voltage industrial signals into logic-level outputs, ideal for enhancing industrial control systems. This board features the MAX22196, a high-performance octal industrial sink or source digital input IC from analog devices. This Click board stands out for its ability to interface eight industrial inputs via SPI, configurable as either sinking or sourcing with built-in current limiters, ensuring adherence to IEC 61131-2 standards. A notable feature includes an on-chip 5V linear regulator, providing up to 20mA of load current, with the flexibility of being powered by a field supply ranging from 8V to 24V. Additionally, it supports serial communication up to 12MHz and features a 3x3 yellow LED matrix for indicating the status of digital inputs.
