Relays provide safe, reliable switching for control systems. They let a low voltage control signal switch a higher power circuit while keeping the control and load sides electrically isolated. - Function and benefit: isolates logic from load, enabling safe operation of motors, pumps, lights and other high power devices from a single controller. - Compatibility: available in common coil voltages and contact configurations to match typical control circuits; suitable for both AC and DC control signals; designed for standard control panels and automation systems. - Size and materials: compact form factor for tight spaces; durable housing and reliable contact materials suited for repeated use; insulating construction for electrical safety. - Performance: predictable switching behavior, long operating life within rated applications, and consistent control of connected loads. - Use scenarios: - In a PLC driven automation line to switch a motor or actuator from a centralized controller. - In a home or building automation system to control lighting or fans via a centralized controller. - In portable or vehicle equipment to switch auxiliary circuits with a relay module designed for that environment.
