Product Description

The SR3B261BD relay module is a Sharp SR3B261BD SSR designed for industrial automation, offering a single-channel input (3-32VDC) and output (240VAC, 2A) for precise electrical load control. This SR3B261BD solid state relay operates within a wide temperature range (-30°C to +80°C) and supports direct interfacing with PLCs or sensors via its 4-pin terminal. With a compact form factor and DIN rail compatibility, it excels in HVAC, packaging, and energy systems. Advantages include zero-noise switching, high reliability, and surge protection, though heat dissipation must be managed for sustained high-current applications. The module lacks onboard communication ports but integrates seamlessly into existing control architectures, ensuring low-maintenance performance in demanding environments.
