Programmable logic controllers (PLCs) are an essential part of the automation sector, particularly factory automation. PLCs are classified as voltage and current inputs and convert real-world signals ...

The MAQ20-BRDG1 strain gage module has four input channels and can interface to full, half, and quarter bridge sensors using four-wire or six-wire connections. All channels are individually ...

Touted as the world’s first TUV SIL 3 certified Hart failsafe analog input module, the Simatic SM 336 is available for use with Simatic ET 200M I/O and PCS 7F process safety systems. July 1, 2008 A 50 ...

In the previous two issues of this newsletter, we looked at troubleshooting digital input modules. Basically, we looked for the presence or absence of a voltage. With analog modules, it's trickier ...

[Scott Harden] has already produced some projects which measure analog inputs. But he’s got plans for more and wanted a base system for graphing analog signals. You can see the small board next to his ...

When inserting an analog switch, the key influencing factor is still the incident wave response, as the switch can be seen as a discontinuity. The switch RC characteristics have to be optimized to ...

Data-acquisition systems are coming to market to help capture real-world analog signals for computer analysis, control, and management. Expanding on our last coverage of the topic in our October 2017 ...
