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 ...

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 ...

The MAXREFDES67# reference design is a complete universal analog input for industrial applications. This unique 24-bit front-end accepts bipolar voltage and current, resistance temperature detector ...

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 ...

Optoisolators—also called optocouplers or photoisolators—are widely used to provide galvanic (ohmic) isolation of digital-signal inputs and outputs in industrial environments, as well as in other ...

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 ...
