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 ...

Beckhoff Automation has extended its range of IP 67 I/O modules with the newEP4374 EtherCAT Box. This flexible, moisture and dust-resistant I/O devicecombines two analog inputs and two analog outputs ...

One popular way to reconstruct analog signals in microcontrollers (µCs) is through pulse width modulation (PWM). However, this modulation produces a large number of harmonic components, which limits ...

Toshiba’s TLP2363 high-speed, standard-footprint optocoupler targets the 24-V digital-input needs of PLCs and industrial devices, while providing galvanic isolation to 3750 Vrms. Optoisolators—also ...

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 ...
