In this chapter, I will present a few useful “cookbook” applications for real-time control circuits designed to perform some specific low-level task and interface with a master controller for ...

Stepper motors are useful for relatively low-speed, intermediate-torque drive and positioning applications, particularly where accurate sub-revolution rotor position control is necessary. Motors of ...

In Part 1 of this two-part series, we presented a 3-phase, 480VAC motor circuit with its associated controls (Figure). We stepped through a logical, systematic approach to troubleshoot the main power ...

Higher Capabilities for Safety-Rated Control Circuits A truly reliable safety control system must work even when some parts fail. Force-guided relays are unseen components that add another level of ...

An overload or short circuit in a fuse or mini circuit breaker can lead to undersupply or failure of an entire 24-V dc power-supply system. Selectivity protection using an electronic fuse offers a ...
