MAXREFDES42 Temp Sensor Reference Design

Analog Devices MAXREFDES42 IO-Link® RTD Temp Sensor Reference Design is a high-accuracy IO-Link resistance temperature detector (RTD) temperature sensor reference design. The Analog Devices MAXREFDES42 is designed for use with a 2-wire, 3-wire, or 4-wire PT100 RTD over a wide temperature range. Built in an industrial form factor, the design uses Maxim's highly integrated MAX31865 RTD-to-digital converter. A rugged, on-board female M12 connector allows off-the-shelf RTDs to be connected to the board using a standard M12 extension cable. The temp sensor performs accurate temperature conversions to 15-bit resolution with multiple fault detection features. A display shows coarse temperatures rounded to the nearest °C, while the IO-Link communication tracks and provides fine temperature values.
