It's time to get a little more specific with what the PLC CPU controls: PLC I/O! This article will discuss discrete I/O, analog I/O and briefly introduce industrial communications protocols. We talked ...

I/O modules are building blocks of industrial control systems used in end equipment such as PLC (Programmable Logic Controllers), PAC (Programmable Automation Controller) and DCS (Distributed Control ...

Editor’s note: Here is an article regarding a new approach to analog isolation. Each application example makes use of a high-current PVI as an isolated power source, a micropower digital isolator, and ...

How to decide between buffered and un-buffered (switched capacitor), high-speed analog-to-digital converters, with an example of anti-aliasing filter design. The fundamental end goal when using an ADC ...
