Product Description

The SR2E121BD relay from Omron's SR2E series is a compact, high-performance electromechanical relay designed for industrial automation and control systems. It features 1 input channel and 1 output contact (SPST-NO) with a maximum switching capacity of 10 A at 250 VAC. The relay operates within a voltage range of 12-24 VDC and supports direct integration with PLCs, sensors, and control modules. It is compatible with industry-standard sockets and offers reliable operation across a temperature range of -40°C to +85°C. Key advantages include high durability, low power consumption, and vibration resistance, making it suitable for harsh environments. However, it lacks built-in communication interfaces, requiring external modules for protocol integration. The SR2E121BD is widely used in machinery, energy management, and automotive applications due to its compact design and consistent performance.
