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 ...

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 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 ...

The Click PLC from AutomationDirect now includes three analog CPU models. They feature two analog inputs and two outputs with voltage ranges of up to 5 vdc or current up to 20 mA. The modules include ...
