Referencedesign for IO-Link temperatursensor
Maxim Integrated’s nye IO-Link temperaturersensor referencedesign kan sænke omkostninger og forøge 'uptime' i industrielle kontrol og automationsapplikationer (in english).
The new MAXREFDES42# IO-Link resistance temperature detector (RTD) joins the company’s portfolio of other IO-Link reference designs for industrial control and automation. This design’s highly integrated analog front end (AFE) measures temperature, while detecting overvoltage, shorts, and open circuits. This is a set of capabilities not found in competitive discrete solutions.The reference design consumes minimal power and provides better than +/-0.5°K accuracy.
The temperature appears immediately on an LED display for a quick and convenient snapshot of coarse temperature values. For user convenience, MAXREFDES42# fits in a standard industrial form factor. For versatility, it supports all three IO-Link speeds—no other competing device can do this. The MAXREFDES42# is available for use with a 2-wire, 3-wire, or 4-wire PT100 RTD over a wide temperature range. Applications include air, gas, and liquid temperature measurement.
The configuration software for this smart IO-Link temperature detector was developed in collaboration with ² Development. The MAXREFDES42# uses 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.
- We are adding this smart temperature sensor to our quiver of IO-Link reference designs to provide our customers with specific, highly integrated solutions, says 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.
Key advantages include:
• Low Power: during operation over a temperature range of -40 °C to +150 °C, the system consumes less than 300mW of power by utilizing an industrial DC-DC step-down converter.
• Highly Integrated: integrated into the front-end is the MAX31865 RTD-to-digital converter which provides flexibility, robustness, and optimal performance for an IO-Link platform.
• Cost Savings: PC control with software saves configuration and maintenance cost and increases uptime.
