Relays are electrically operated switches that allow a low power control signal to switch a higher power circuit. They provide isolation between control and load, enabling safe, remote, and automated switching of electrical devices. Key benefits - Safe isolation: protects control electronics from high power loads. - Flexible control: switch from sensors, controllers, or automation systems. - Versatile configurations: available in common contact arrangements to fit your wiring needs. - Reliable operation: designed for repeated switching with consistent performance. Core attributes - Function: coil energizes to move contacts; available as normally open or normally closed. - Compatibility: supports standard control signals and common coil voltages; variants for SPST, SPDT, DPDT as needed. - Size: compact form factor suitable for tight spaces and various mounting options. - Material: built for durability with suitable casing and contact materials for switching applications. - Performance: provides stable, repeatable switching with long service life under appropriate ratings. Use scenarios - Home automation: energize a relay from a smart switch or hub to control lights, fans, or pumps. - Industrial control: interface a PLC or controller with higher power devices such as motors, pumps, or heaters, while keeping control circuitry isolated. - Power management: switch auxiliary loads in battery systems, UPS, or charging circuits for safe and orderly operation. Note: actual coil voltages, contact ratings, and mounting options vary by model. Refer to the specific relay model for exact specifications and suitability to your application.
