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 ...

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 ...

In part one of this series, we looked at the PLC’s internal architecture, briefly discussed Ladder Logic programming, Human-Machine Interfaces, advantages of the PLC’s ability to react consistently ...

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 ...

AutomationDirect’s Productivity2000 programmable controller line now includes 12 and 13-bit resolution current and voltage analog input and output modules for cost-conscious applications.

Though PLC (programmable logic controller) programming languages may not receive the attention that general computing programming languages, such as JavaScript, C#, or Python do, they remain critical ...

The DRSL-U accepts a wide range of inputs, including RTD, thermocouple, potentiometer, linear resistance, current or voltage input and converts these signals to linear current or voltage output. The ...
