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 ...

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 ...

In industrial automation, analog input modules serve as the critical bridge between field sensors and control systems, converting real-world physical measurements into digital data that drives process ...

are process and control implementations that cover everything from test labs and fabrication plants to military and medical electronics to basic data acquisition. They leverage various sensor types ...

The PuffinPLC Project is an effort to produce a Linux-based GNU Public Licensed Programmable Logic Controller (PLC). PLCs were developed in the 1960s to replace the complex electrical relay circuits ...
