Product Description

The SR2B121BD relay is a compact SSR (Solid State Relay) module designed for industrial automation and control systems. It features a single-channel input (3-32V DC) and output (24-240V AC), enabling direct interfacing with low-power control circuits to manage high-voltage loads. This SR2B121BD module supports TTL/PLC-compatible logic signals and can operate in temperatures ranging from -30°C to 80°C, suitable for harsh environments. With zero-crossing detection, it minimizes electrical noise and ensures stable switching for resistive or inductive loads. Its key advantages include fast response, silent operation, and high durability compared to mechanical relays, though heat dissipation may require thermal management. Ideal for industrial heating, motor control, and lighting systems.
