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 ...

Does the module's output correspond correctly to its input? Determine that by forcing the PLC output to 10%, 25%, 50%, 75%, and 90% and measuring on the output terminals at the corresponding range ...

At the heart of many industrial automation and process-control systems, programmable logic controllers (PLCs) monitor and control complex system variables. Employing multiple sensors and actuators, ...

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 ...
