Jun 27, 2021 · What is a Latching Relay? A latching relay (also known as a bistable, keep, impulse, stay relay, or simply a “latch”) is defined as a two-positional electromechanical switch. …

Jul 9, 2024 · In summary, Figure 1 offers a comprehensive visual representation of a bi-stable relay, highlighting its dual-coil configuration, distinctive symbol, and key contacts.

Bistable relays use much less current, or amperage, which in turn create less heat and allow the vehicle’s computer (the engine control module, or ECM) to operate at a cooler temperature.

In this article we show the intricacies of bistable relay control, analyse a few simple circuits, mention the pros and cons and, finally, introduce the ded-icated drivers type DRT5 and DRL5.

Then it describes a portable test circuit for 12V bistable relays with a double coil, which includes a diagram and economical discrete components powered by a 9V battery, to test the operation …

The bistable relays are mainly used for remote and automatic controls where there is often a need for contactors which have two stable contact positions, even in the dead state. The application …

This simple circuit turns on and off a coil with a momentary switch, then it works as a bistable relay. The circuit is supplied by 12 Volt DC power supply and drives a 5 Volt -125 ohm coil.

BI-STABLE RELAY WIRING DIAGRAM.
