The Phoenix PLC-BSC-24DC/21/SO46 belongs to the proven PLC-INTERFACE product family, known for its reliability and ease of integration into DIN rail-based control systems. This Relay Socket supports 24 V DC nominal input voltage and features an integrated freewheeling diode that protects control circuits from voltage spikes generated by inductive loads. The screw connection method ensures solid contact and long-term performance, accommodating both rigid and flexible conductors ranging from 0.14 mmΒ² to 2.5 mmΒ², or AWG 26 to 14. Designed for space-constrained enclosures, it measures just 6.2 mm wide and 80 mm high, and supports DIN rail mounting in any orientation. The enclosure is finished in gray (RAL 7042) and made of UL 94 V0 flame-retardant material to meet safety standards. It operates reliably in temperatures from -40 Β°C to +55 Β°C and complies with EMC Directive and Low Voltage Directive requirements for global industrial compatibility. An integrated yellow LED indicator provides quick visual feedback during diagnostics or panel inspection.
The PLC-BSC-24DC/21/SO46 is specially designed for applications requiring interference filtering and signal integrity in control panels, PLC systems, and relay-driven automation lines. It is commonly used in sensor-actuator wiring, relay-based logic circuits, and control outputs where electrical noise must be minimized. Maintenance engineers benefit from the secure screw terminals and reliable LED status feedback during routine service and relay replacements. Panel builders value its compact size and component compatibility, especially when assembling dense I/O blocks. For engineering students and trainees, this socket offers an ideal foundation for learning relay interfacing, visual troubleshooting, and control logic behavior. With safe insulation, fast mounting, and high surge durability, this relay socket provides dependable electrical performance and mechanical integrity in all common industrial settings, including manufacturing, packaging, process control, and utilities.
