The Phoenix PLC-BPT-24UC/21HC belongs to the trusted PLC-INTERFACE series, built for compact relay control applications. This Relay Socket supports a 24 V AC/DC nominal input voltage and uses a convenient push-in connection system that allows fast, tool-free wiring of rigid and flexible conductors ranging from 0.14 mmยฒ to 2.5 mmยฒ or AWG 26 to 14. Measuring just 14 mm in width and 80 mm in height, it fits neatly into tight DIN rail layouts, allowing for high-density installations in modern panels. The housing is built with UL 94 V0-rated flame-retardant material and finished in gray (RAL 7042), giving it a clean, industrial look that matches standard panel components. It operates within a broad ambient temperature range of -40 ยฐC to +60 ยฐC, suitable for rugged shop floors and electrical rooms. A built-in bridge rectifier circuit enhances relay protection during switching, and the integrated LED status indicator provides immediate visual feedback, which simplifies diagnostics and maintenance. With compliance to Low Voltage Directive and EMC Directive requirements, this socket is engineered to meet global industrial standards.
The PLC-BPT-24UC/21HC is ideal for applications that involve high continuous current switching, such as relay-controlled contactor circuits, process control signaling, and distributed I/O systems. Itโs highly valued in industries like packaging automation, textile manufacturing, and utility substations where compactness and durability are crucial. For junior engineers, the push-in connection system reduces installation time and error chances. Senior maintenance engineers appreciate its secure connections during replacements and upgrades. In training labs, the LED indication and accessible wiring terminals provide practical learning without compromise on safety. Its design supports DIN rail mounting in any orientation, ensuring installation flexibility across all types of panels. This product brings together the durability, connection quality, and compliance required for reliable long-term relay operation in control systems.
