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 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 ...

Digital/binary sensors and switches are essential for signal monitoring and system control in industrial control, industrial automation, motor control, and process automation. All the sensors’ outputs ...

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 ...

Designers now have a way to reduce power, system cost, and size for programmable logic controller (PLC) digital-input subsystems, with the Corona (MAXREFDES12#) reference design. This design reduces ...
