Industrial control systems can be categorized in two types: open-loop and closed-loop systems. The open-loop control system is a continuous control system that provides no feedback from its output.

This technical document discusses a simple method of converting a PWM output signal into an analog output signal employing a Hall effect sensor or PWM sensor. This article covers the behavior of PWM ...

An experienced circuit-design EE once clarified his view of the hierarchy of IC-vendor design support: High-performance, feature-rich ICs were good, application circuits were better, but complete ...

In our previous two issues, we discussed troubleshooting digital output modules. Troubleshooting analog modules is a bit more complicated, for two reasons: Analog modules aren't on/off, as digital ...

The Industrial Automation Group of Advantech introduces its first integrated I/O controller, the PEC-3710. Featuring an AMD LX800 500 MHz controller with 16-channel analog input, 4-channel analog ...

So I'm building a new HTPC. Currently mine doesn't have enough HP to do hi-def well enough for my tastes. Anyway, I find myself slot limited as in my mobo has SPDIF output but via a header which ...

For a circuit to perform a useful action, it must receive data (input) to which it will respond with an action (output). Think of a child’s toy where a press of a button turns a light turns on, and ...

New AC and DC discrete I/O modules include 8-point, 100-120 VAC input and output modules, 8- and 15-point, 3.3-24 VDC input and output modules and high-density, 32-point,12-24 VDC input modules. The I ...
