When you get the call, “The motor won’t start,” you’d best have a logical and systematic plan in place to approach the problem. “Easter egging” just doesn’t work unless you happen to be very lucky!

Circuits that fall under the requirements of Art. 725 are remote-control, signaling, and power-limited circuits that aren’t an integral part of a device or appliance. Article 725 includes circuits for ...

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 ...

Part 3: Thermistor SPICE Models Make Sense With Older ICs, but What About a Newer One, Such as the LTC1041? It’s with a somewhat provocative title that we begin the third and last installment in this ...

AutomationDirect announces the release of a new White Paper, “Basic Pneumatic Circuits”, which discusses common pneumatic circuits that can be used alone or as building blocks in larger pneumatics ...

What are HVICs? High-voltage integrated circuits (HVICs) translate low-voltage control signals to levels that are suitable for driving power switches in high-voltage applications. HVICs also can ...

A few months back, a dynamic voltage-controlled thermistor SPICE model was presented on planet analog, A Multi-Simulator NTC Thermistor SPICE Model With Temperature Driven By a Voltage With the help ...
