This Design Idea shows how to use a 63¢ (Q=1) microprocessor reset voltage detector IC in a relay coil drive circuit to greatly reduce the coil’s hold-in current. When asked to estimate the coil ...

Acceptable ohm reading for a good current relay. One type of starting relay used on fractional-horsepower compressors is the current relay. This type of starting relay uses the initial high inrush ...

Beverly, Mass. — Designed to replace electromechanical devices, a new current limiting, normally open, 1 Form A optically isolated solid-state relay (SSR) from Clare Inc., an IXYS company, saves board ...

Expanding the SeaDAC family of USB data-acquisition devices, the SeaDAC PLC-16H digital I/O module combines high-current Form C relay outputs and optically isolated inputs. It includes eight SPDT high ...

The ADAM-6066 is a high current relay output module designed to meet the requirements of power switching applications. The ADAM-6066’s six relay output channels are rated at 5A at 240VDC, and support ...

When I think of economizer circuits for solenoids and relays, I’m reminded of the phrase, “you can’t have your cake and eat it, too.” This phrase comes to mind because if you use a solenoid economizer ...

The G9KJ provides an alternative to general‑purpose high‑voltage components, allowing designers to specify pre‑charging circuits for optimal rating, reliability, cost and size. With a maximum contact ...

IIIF provides researchers rich metadata and media viewing options for comparison of works across cultural heritage collections. Visit the IIIF page to learn more. Telegraph relays amplify an ...
