This is a specific configuration of the miniature Omron H3Y-2 series timer. It is a plug-in, solid-state ON-delay timer rated for a 200 to 230 VAC power supply with a fixed full-scale time range of 5 seconds. The front panel features a clear analog knob with a red pointer, an explicit "sec" unit label, and dual LED indicators for power input (PW) and time-up output status (UP).
