Schneider Electric RE9RA21MW7 Industrial Relay

Schneider Electric RE9RA21MW7 is an industrial timing relay from the Harmony Time family that provides a reliable off-delay timing function for automation circuits. It delivers a 3 to 300 second off-delay window with a solid-state output and is designed for 240 V AC control, making it suitable for timer-based control of loads in machines, conveyors, and other automation equipment. Part of the RE9 Zelio modular timer lineup, Schneider Electric lists this reference as discontinued for commercialization on 31 March 2022, with end-of-service on 11 May 2022, and recommends the RE17LCBM off-delay timing relay as its replacement. Some distributor listings reference this model with a 24–240 V input range, reinforcing its use in common low- to mid-voltage control circuits while maintaining the same timing window and solid-state output.
