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 robust DC-to-AC switching module designed for demanding industrial applications. It accepts a low-voltage DC control signal ranging from 3 to 32 VDC, making it fully compatible with PLCs, microcontrollers, and other automation systems. On the output side, it handles load voltages from 24 to 480 VAC at up to 40 amps of continuous current, giving it the muscle needed for heavy-duty equipment control. The relay features zero-crossing switching technology, which significantly reduces electrical noise and helps extend the service life of connected devices. Optical isolation between the control and load circuits provides an added layer of safety and strong noise immunity. The clear protective cover shields the terminals while still allowing easy visual inspection, and the built-in LED indicator confirms when the relay is active. Its compact, panel-mount-ready housing makes installation in control cabinets straightforward. Compatible with both 50 and 60 Hz systems, this SSR module is a reliable choice for motor control, heating systems, lighting, and other industrial switching needs.

• DC TO AC CONTROL: Accepts a 3–32 VDC control signal, making it fully compatible with PLCs, microcontrollers, and other low-voltage DC control systems.
• HIGH-CAPACITY OUTPUT: Handles up to 40A continuous load current across a wide output voltage range of 24–480 VAC at 50/60 Hz for demanding industrial applications.
• ZERO-CROSSING SWITCHING: Switches at the zero-crossing point of the AC waveform, minimizing electrical noise and reducing stress on connected equipment.
• OPTICAL ISOLATION: Fully optically isolated between the control and load circuits, providing enhanced safety and strong immunity against electrical noise interference.
• COMPACT & EASY TO MOUNT: Features a standard panel-mount design with a bottom mounting hole, allowing straightforward installation in control panels and enclosures.
