Siemens 7PU5220-1AJ20 Multi-Function Solid-State Timing Relay is a compact solid-state clock-pulse relay designed for surface mounting in control panels. It operates from 110–127 V AC at 50/60 Hz and features a single changeover output with two LED indicators to monitor timing activity. With a clock-pulse timing range of 0.6 to 6 seconds, it enables precise, repeatable delays for sequencing tasks in automation equipment without mechanical contacts.
