Schneider Electric RE48ATM12MW Harmony RE48 5A 2CO On-Delay Timer Relay

The Schneider Electric RE48ATM12MW is a Harmony RE48 on-delay plug-in timer relay with 2 C/O timed contacts rated 5 A, powered by a 24-240 V AC/DC universal supply. It runs a single power on-delay function (A1: delay on energization), with delay settings adjustable from 0.02 seconds to 300 hours via a front-panel selector, and mounts on an 8-pin sub-base.

Selection Notes

Unlike the AMH13MW and AML12MW multifunction variants in the same RE48 family, this reference runs a single fixed timing function - power on-delay (A1) - rather than a selectable function set, which simplifies commissioning where only one delay behavior is ever needed; the front-panel selector still sets the delay range and value. It shares the same 8-pin sub-base as the RE48AMH13MW, so it drops into that socket where only on-delay timing is required. Two C/O contacts rated 5 A/250 V AC (1250 VA breaking capacity) drive a contactor coil or switch two independent circuits directly.

Applications

Used where a fixed power on-delay is the only timing behavior needed - staged equipment start-up, pump priming delay, or delaying an alarm output after power-up - on an 8-pin socket.
