Designing, installing, and maintaining control systems involves a lot of wires. Each wire has a purpose, often indicated by the color of the insulation. But what are the common colors, and what do they mean?

Large motors require a circuit to turn on and off. This may be as simple as a single on/off drum-type switch or as…

Large motors require a circuit to turn on and off. This may be as simple as a single on/off drum-type switch or as elaborate as a VFD unit. Learn about some common control circuit designs for typical three-phase motor requirements.

We are taught that parallel circuits maintain equal voltage across all branch resistors, equally sharing the source…

We are taught that parallel circuits maintain equal voltage across all branch resistors, equally sharing the source voltage. But reality is often far from ideal, and individual devices certainly impact the rest of the circuit.

Despite the many overlaps, PLCs and RTUs are two different devices, each with specific suitable applications.

Any machine can become a source of elevated temperature, even under regular operation. We cannot assume that temperature problems occur only based on climate conditions, and mitigation steps must be employed.

Learn about the common applications, programming procedures, and safety protocols of collaborative robot work cells,…

Learn about the common applications, programming procedures, and safety protocols of collaborative robot work cells, which are often simpler and less expensive than industrial robot work cells.

DC voltage systems exist to provide controllers and field devices with stable power, but it is not always clear when these systems should be bonded with the earth ground of the AC line voltage supply.

Power supplies tend to get a reputation as one of the most important power considerations of a DC control circuit - but…

Power supplies tend to get a reputation as one of the most important power considerations of a DC control circuit - but we can’t ignore other key players: power filters, converters, and backup power modules.
