Schneider Electric RE48AML12MW Electronic Timer Relay

Schneider Electric RE48AML12MW is a two-function multifunction timer relay in the Harmony RE48A / Harmony Time series, designed for industrial control and automation to deliver precise timing and sequencing across a range from 0.02 s to 300 h. It operates from 24 to 240 VAC/DC at 50/60 Hz and uses DPDT (2 C/O) AgNi (cadmium-free) contacts rated 5 A at 250 VAC/DC, mounted on a 48 × 48 mm front panel with an 11-pin plug-in sub-base. The device features IP50 protection on the front and IP40 on the housing, housed in self-extinguishing plastic, with timing set via a rotary dial or selector switch, and supports panel-mount or plug-in installation in environments from -20°C to +50°C. It adheres to IEC 61812-1, UL, CSA, cULus, and CE standards, making it suitable for control panels, packaging machinery, conveyors, HVAC, and process automation where adjustable time delays improve sequencing and reliability. Common replacements include RE48ATM12MW, RE48AMH13MW, and RE48ACV12MW.
