SSR-25DA SSR-40DA SSR-40AA SSR-40DD SSR 10A 25A 40A 60A 80A 100A DD DA AA Solid State Relay Module for PID Temperature Control (SSR-25A AA)

The SSR-40 DA Solid State Relay Module is a reliable and versatile switching solution designed for PID temperature control and a wide range of industrial applications. Available in multiple configurations — including DA (DC to AC), DD (DC to DC), and AA (AC to AC) — and current ratings spanning 10A to 100A, this module offers exceptional flexibility to suit your specific system requirements. The SSR-40 DA accepts a low-voltage DC input of 3–32V and controls an AC load of 24–380V, making it ideal for seamless integration with microcontrollers and PLC systems. Its compact chassis-mount design measures approximately 0.906 x 1.77 x 2.36 inches, fitting neatly into control panels and enclosures. Built with aluminum construction and zero-crossing switching technology, it ensures smooth, interference-free operation. The module carries UL recognition for added assurance of quality and safety compliance. Clearly labeled terminals make wiring straightforward, even for complex setups. Whether you're building a temperature controller, automation system, or industrial switching circuit, this solid state relay module delivers consistent, long-lasting performance.
