Negative Effects of Grounding (Earthing) a DC Power Supply

Negative Effects of Grounding (Earthing) a DC Power Supply

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 for Control Circuits: It’s Not Just Power Supplies

Power for Control Circuits: It’s Not Just Power Supplies

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.


Contactors versus Relays - Differences and Applications

Contactors versus Relays - Differences and Applications

Although the are similarities in operating theory, relays and contactors are used in industrial circuits for different specific applications, and should not be used interchangeably.


Dynamic Braking Resistors for Motor Control Applications

Dynamic Braking Resistors for Motor Control Applications

Large DC and AC motor drives often provide terminals for installing a braking resistor. What are these resistors, and how do they slow down a machine? What hazards and cautions must be considered?


Introduction to Safety Relays

Introduction to Safety Relays

Redundancy and safety are often seen together in industrial safety systems. Safety relays monitor emergency devices to switch contacts based on status - but what makes them different from normal relays?


Methods of Marking and Labeling for Wiring and Tubing

Methods of Marking and Labeling for Wiring and Tubing

Labels are such a small detail in the world of robotics and automation, they are often given very little attention. However, they play a vital role in proper system function - from installation to troubleshooting.
