Relays are electromechanical switches that enable a low voltage control signal to switch a separate load circuit, providing electrical isolation between control and power. This allows safer, controlled operation of higher current or higher voltage devices from simple control electronics. Key benefits - Safe, reliable control of high current or high voltage devices from small control signals. - Available in multiple contact configurations and coil options to fit your system. - Compact, robust construction suitable for PCB mounting or panel installation. - Consistent switching performance with low contact resistance and long service life. Key attributes - Function: electromechanical switch that opens or closes a separate circuit. - Compatibility: designed to interface with common control electronics and drivers; verify coil voltage and load ratings against the model datasheet. - Size: offered in a range of footprints to fit space constraints. - Material and durability: designed for durable operation; consult the datasheet for insulation, mounting, and contact material details. - Performance: coil voltage, contact rating, and form factor vary by model; refer to the specific datasheet for exact values. Applications - Home automation: control lighting or small powered devices from a microcontroller or smart relay module. - Industrial control: switch motors, heaters, or solenoids under PLC control. - Sensing and safety: isolate sensor circuits from mains to improve safety and reduce interference.
