Product Description

The SR2B121B relay, part of the SR2B series relay family, is a 12V 1A signal relay designed for precise low-power switching in industrial control systems. It features a single-pole single-throw (SPST) configuration with one input and one output channel, supporting direct integration with up to two auxiliary modules for expanded control. Compatible with standard digital interfaces like SPI and I2C, it operates within 9-24V DC and a temperature range of -40°C to +85°C, ideal for automation, HVAC, and energy management applications. Compact dimensions (20mm x 15mm x 10mm) and a robust build ensure reliability in high-vibration environments. While its 1A current limit restricts high-power use, its low coil power consumption (120mW) and fast response time (<5ms) make it optimal for signal-level circuits. No onboard battery or display, ensuring minimal footprint.
