Relays What it is An electrically operated switch that uses a coil to open or close contacts, enabling a control signal to switch a separate load circuit. It provides galvanic isolation between the control side and the load. Why you need it Allows lowpower control of power devices, protecting control electronics and enabling safe, reliable automation. Supports switching of different load types while keeping control circuitry isolated. Key benefits Safe and reliable control of circuits with minimal interference to the control system Flexible configurations to match different wiring schemes and load requirements Compact form factors suitable for PCB or panel mounting Durable construction designed for long service life and repeatable performance Core features Multiple contact configurations (for example single pole, double pole, throw options) A range of coil voltage options to fit common control signals Compact size for tight spaces and dense layouts Robust housing and contact materials designed for dependable switching Clear separation between coil and contacts to protect control electronics Compatibility and suitability Designed to work with standard control signals from microcontrollers, PLCs, and automation modules Suitable for a wide range of loads and power supplies, depending on model Available in options that support PCB mounting or panel mounting Size, material, and performance Small footprint without sacrificing switching capability Built for reliable operation in typical industrial and consumer environments Consistent switching characteristics and load handling across cycles Use scenarios 1) Home automation: control lighting or climate devices from a lowcurrent controller 2) Industrial control: interface sensors and control panels with motors, heaters, or pumps 3) Equipment and machinery: manage indicators, signaling circuits, or safety interlocks within control panels Maintenance and longevity Designed for long cycle life with minimal maintenance Documentation provides guidance on replacement intervals and compatible accessories
