INDUSTRY 4.0

Conclusion
The digitisation of factories brings increased production
output, factory utilisation and labour productivity. However,
the transition to the digital factory is a challenge because
legacy systems lack 10BASE-T1L supported sensors and
actuators. The AD74413R software configurable I/O coupled
with the ADP1032 bridges the gap for ethernet-enabled
field instruments. The four channels of the AD74413R are
flexible and can each be programmed into eight different I/O
configurations. Its fault detection and diagnostic capabilities
save time during the debugging and commissioning of a
system. The diagnostic capability can also be used to monitor
systems for maintenance. Finally, the ADP1032 galvanically
isolates the data and power sources, ensuring the safe and
efficient transfer of power and data. n
