Quad IO-Link Master reference design evaluates industrial sensors

April 14, 2015 // By Graham Prophet
Maxim Integrated’s MAXREFDES79# IO-Link master features four ports and a complete software stack in a development platform;it gives designers a single platform to rapidly develop their own IO-Link master and multiple industrial sensors.

As the first IO-Link master reference design, MAXREFDES79# reduces the cost and time required to develop and evaluate both IO-Link master and IO-Link sensor systems. While previous IO-Link master development units featured only one port, Maxim’s reference design IO-Link master allows up to four sensors to be tested at one time. As an IO-Link compliant system, MAXREFDES79# works with any IO-Link sensor. It complements four Maxim sensor reference designs (MAXREFDES23# light sensor, MAXREFDES27# proximity sensor, MAXREFDES36# 16-channel digital input, and MAXREFDES42# RTD temp sensor) to simplify the process of simulating factory operation.

MAXREFDES79# is a highly integrated development platform with software stack. The system has four ports, one for each IO-Link master (MAX14824) and integrates power supply products. The design uses the industry’s fastest (400 µsec) COM 3 communication, comes with an adapter, and is enabled with a microUSB data connection.

The MAXREFDES79# board with software stack is available for $500. The initial unit costs $415. Hardware and firmware design files, as well as test data, are provided free and available online.
