The Phoenix PLC-BSC-230UC/21-21/SO46 is a part of the high-performance PLC-INTERFACE series and is built for seamless integration into 230 V AC input control circuits. Featuring a robust M3 screw connection system, this Relay Socket securely handles rigid and flexible conductors from 0.14 mm² to 2.5 mm², or AWG 26 to 14. It comes equipped with a bridge rectifier protective circuit that reduces reverse polarity risks and electrical interference. The socket’s form factor—14 mm width and 80 mm height—makes it ideal for DIN rail installations in compact cabinets, while the UL 94 V0-rated housing ensures flame resistance and durability. It operates effectively within -40 °C to +55 °C, maintaining stability in both cold and heat-prone environments. An integrated yellow LED status display enhances visibility during operation and troubleshooting. The component complies with EMC and Low Voltage Directives, and includes insulation rated for high-voltage applications, with a typical release voltage of 70 V AC and a response time of 7 ms. Its reliable performance, standardized dimensions, and global safety certifications make it a preferred choice for industrial automation professionals.
The PLC-BSC-230UC/21-21/SO46 is best suited for use in relay logic circuits where interference filtering is essential—such as in signal conditioning for sensors, actuators, or relay-controlled power distribution blocks. Panel builders benefit from the time-tested screw connection design and the integrated LED for fast visual confirmation during testing. For maintenance engineers, the product offers consistent performance, safe handling, and quick relay replacements without disturbing adjacent wiring. Educational institutions and training labs use it to teach practical relay logic, visual diagnostics, and DIN rail mounting techniques. With its compatibility for relays like REL-MR-110DC/21-21AU, and its ability to support wide voltage ranges and filter noise effectively, this socket is trusted across industries including manufacturing, energy, machine tools, and building automation.
