The Phoenix RIF-2-BSC/4X21 is part of the industrial-grade RIFLINE complete relay family and is built to withstand demanding conditions in electrical automation systems. This Relay Socket supports a maximum rated input of 250 V AC/DC and can handle up to 12 A current, depending on the assembly and application setup. It uses a solid screw connection method to ensure stable electrical conductivity, accommodating rigid and flexible conductors between 0.5 mmΒ² to 4 mmΒ², or AWG 20 to 10. The unit features a stripping length of 8 mm and tightening torque between 0.5 to 0.6 Nm for precise and secure terminal clamping. With a form factor of 27 mm width and 89 mm height, and mounting depth of 75 mm (with bracket), the socket fits DIN rail systems with ease and supports any mounting orientation. The gray RAL 7042 flame-retardant housing (UL 94 V2) provides long-term reliability, while its wide temperature operating range from -40β―Β°C to +85β―Β°C makes it suitable for both industrial environments and field installations. Protection features depend on the selected suppressor modules, allowing custom circuit protection according to application needs.
The RIF-2-BSC/4X21 is widely used in relay interface applications across sectors like power distribution, machinery automation, and HVAC control. Itβs particularly effective where high-current switching and reliable isolation are required in control panels. Senior maintenance engineers rely on its rugged screw terminals and clear labeling for quick relay replacements during servicing. For junior engineers and students, it offers real-world exposure to standard relay socket architecture used in modern PLC and I/O systems. OEM panel manufacturers prefer this model for its robust design and flexibility to support various relay modules. The socket is fully compatible with Phoenix Contactβs miniature relays like REL-MR-110DC/21-21AU, enabling consistent modular expansion. Whether for industrial upgrades or new installations, the RIF-2 socket offers dependable performance and clean integration.
