The Dayton 5YP78 120V Relay is a versatile and reliable electronic component designed for various applications. This relay operates on a 120V AC power supply, making it suitable for use in North American electrical systems.
The 5YP78 is a single-pole, double-throw (SPDT) relay, meaning it has one input and two outputs. This configuration allows for the switching of one circuit to another, or the switching of a circuit on and off. The relay has a contact rating of 10A at 600V AC, making it suitable for handling moderate current loads.
The Dayton 5YP78 relay features a form C contact arrangement, which means the normally open (NO) contacts are connected when the relay is in its deenergized state, and the normally closed (NC) contacts are closed when the relay is deenergized. When the relay is energized, the NO contacts open, and the NC contacts open.
The relay has a coil voltage of 12V DC, which is typically supplied by a control circuit. The coil has a resistance of 240 ohms, which allows for easy calculation of the necessary current to energize the relay. The coil is rated for 0.5A, which means it can handle up to 0.5 amperes of current.
The Dayton 5YP78 relay is designed with a latching mechanism, which means it remains in the last position it was activated until it is manually reset or deenergized. This feature makes it ideal for applications where a constant state of operation is required, such as in alarm systems or timers.
The relay has a compact size, measuring 2.0 inches in length, 1.0 inch in width, and 0.7 inches in height, making it easy to integrate into various applications. It is also RoHS compliant, which means it contains no hazardous substances.
In summary, the Dayton 5YP78 120V Relay is a reliable and versatile electronic component that is suitable for various applications. Its SPDT configuration, form C contact arrangement, and latching mechanism make it a versatile choice for switching circuits in a wide range of applications. Its compact size, RoHS compliance, and 10A contact rating make it a reliable and cost-effective solution for many electrical needs.
