The Schneider Electric RHR-411M (RHR411M) is a 230 V AC Harmony timer relay with four changeover (Form-C) contacts that plugs into Harmony RXM2 or RXM4 sockets. It features a built-in noise-suppressing circuit to minimize arcing on switching and protect adjacent electronics. Timing is adjustable from 0.2 to 300 seconds, enabling precise delay control for sequencing and timed switching of multiple circuits in automation systems.
