SSR-1 D4840 Solid State Relay DC to AC 24-480VAC Load Voltage 40A SSR Module Industrial

The SSR-1 D4840 Solid State Relay is a reliable and high-performance DC-to-AC switching module designed for demanding industrial applications. With a wide load voltage range of 24 to 480VAC and a robust 40A current rating, this relay is built to handle heavy-duty power loads with ease. The solid state design eliminates mechanical contacts entirely, resulting in silent operation, reduced wear, and an exceptionally long service life compared to traditional electromechanical relays. The DC control input accepts 3 to 32VDC, making it fully compatible with PLCs, microcontrollers, and other low-voltage control systems for seamless integration into automated setups. Built-in zero-crossing switching technology minimizes electrical noise and reduces inrush current, protecting both the relay and connected equipment. The unit supports 50/60 Hz frequency and features a clear protective cover over the terminals for added safety. A built-in LED indicator provides a quick visual confirmation of the relay's active status. Compact and straightforward to install, this SSR module is an excellent choice for temperature controllers, motor controls, and other industrial switching applications.
