9AS3D5 is a Harmony power relay designed for electrical control and switching applications. It features a Single Pole Single Throw (SPST) normally open (NO) contact configuration, allowing a control signal to switch an electrical load while maintaining isolation between the control and power circuits. The relay uses silver alloy contacts for reliable switching performance and is suitable for industrial control systems, automation equipment, and general-purpose switching applications. Its silver alloy contacts help ensure dependable switching performance, while its mechanical durability of 10 million operating cycles supports long service life and reduced maintenance requirements. It features an SPST switching function with a normally open (NO) contact arrangement and silver alloy contacts. It offers an average coil consumption of 0.9 W, an operating time of 20 ms, and a reset time of 10 ms. It measures 50 mm (H) x 27.3 mm (W) x 27.8 mm (D) and weighs approximately 0.032 kg. The relay is designed to operate in ambient temperatures ranging from -40°C to +40°C and can be stored in temperatures between -40°C and +85°C. The range offers solutions suitable for a wide variety of control panel, machinery, and automation applications requiring consistent and reliable relay performance.
