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 ...

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 ...

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 ...

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 ...

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 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 ...

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 ...

Designers of digital systems are familiar with implementing the 'leftovers' of their digital design by using FPGAs and CPLDs to glue together various processors, memories, and standard function ...

Telecom and data-communications equipment commonly use small-formfactor pluggable (SFP) modules for the physical-layer interface. Also common in these systems is an I 2 C bus for the management data ...
