Industrial IoT pays off big in terms of reduced maintenance and operating costs. As Paul Rako discovered, implementing an IO-Link chip can help cultivate those advantages by managing the power in your designs.
With the heavy use of 12-V accessory devices in applications from automotive to industrial, it’s crucial that design engineers know the quality of device they’re using, especially imported products that may not go through proper testing.
Determining self-discharge involves making just two open-circuit voltage measurements, but one must consider relaxation and voltmeter accuracy when grading cells. Delta-OCV is the tried-and-true method, but quicker options are emerging.
