The Schneider SR2E121FU is engineered to operate within a wide supply voltage range of 85V to 264V AC, offering flexibility in global industrial applications. With a maximum supply current of 30 mA at 240V and 80 mA at 100V, this Zelio Logic smart relay ensures efficient operation in both high and low-voltage environments. It includes 4 relay outputs, each with a thermal current capacity of 8A, suitable for switching AC loads up to 250V and DC loads up to 30V.
With a precise cycle time of 6–90 ms and switching capacity of ≥10 mA at 12V, the SR2E121FU supports a wide variety of control tasks. It handles discrete input signals at 100–240V AC and features an input impedance of 350 kΩ. Built for endurance, it is compliant with IEC 60947-5-1 standards and rated for 500,000 electrical operations across relay outputs. The unit operates reliably across temperatures from -20°C to +55°C and at altitudes up to 2000 meters. Its integrated protection against terminal inversion and screw terminal connections make it ideal for compact, high-performance installations.
The SR2E121FU Smart Relay is perfectly suited for small-scale automation systems such as industrial lighting, HVAC equipment, basic motor control, and timed processes in packaging and building management. With 4 relay outputs and wide voltage input support, it eliminates the need for multiple relays and simplifies wiring in control panels.
This model is ideal for electrical maintenance engineers, machine builders, and automation professionals who require a compact, affordable logic control solution without the complexity of a full PLC. Its reliability, ease of use, and global voltage compatibility make it a trusted choice for both OEM applications and retrofitting legacy systems.
