Product Description

The R312B Power Relay is a compact SPDT relay module designed for industrial control and automation systems. Featuring a robust 10A/250V AC contact rating, it supports single-pole double-throw (SPDT) switching with one input channel and direct compatibility for daisy-chaining multiple modules. Operating at 12-24V DC control voltage, this relay module integrates a built-in RS-485 interface for seamless communication in networked environments. Ideal for HVAC, telecommunications, and process control applications, it operates reliably across -20°C to +70°C with vibration-resistant construction. The R312B Relay Module offers low power consumption and screw-terminal connectivity for easy installation, though its open-frame design requires external enclosure in harsh conditions. With a 30mm x 45mm footprint, it enables space-efficient integration in control panels without onboard power storage or display components.
