Highly Integrated IO-Link® Temperature Sensor


Highly Integrated IO-Link® Temperature Sensor

The new MAXREFDES42# is a highly accurate IO-Link temperature sensor reference design for use with a 2-wire, 3-wire, or 4-wire PT100 RTD over a wide temperature range. The design makes use of Maxim Integrated’s highly integrated MAX31865 RTD-to-digital converter which is built in an industrial form factor. Designers can save power, cost, and space with this IO-Link temperature sensor reference design (RD) that definitely increases uptime for industrial control and automation.

The configuration software for this smart IO-Link temperature detector was developed in collaboration with IQ² Development. The MAXREFDES42# its their IO-Link device stack to communicate with any IO-Link version 1.1-compliant master. This software control lowers operating cost because it enables fast setup, diagnosis, and event monitoring from a PC and without a trip to the installation site. Maintenance can be done at the PC and not on the floor.


“Maxim and IQ2 are two companies on the cutting edge of IO-Link,” said Frank Hörz, Project Manager at IQ2. This collaboration represents another successful design that can reduce our customers’ time to market and lower their operational costs too.”

“We are adding this smart temperature sensor to our quiver of IO-Link reference designs to provide our customers with specific, highly integrated solutions,” said David Andeen, Director of Reference Designs at Maxim Integrated. “Our highly integrated RTD-to-digital converter and IO-Link transceiver create a design rich in benefits with many, clear applications in the industrial space.” For more information about MAXREFDES42#, visit https://www.iq2-development.com/iqmaxrefdes42/.
