The Omron MY4N-GS AC220/240 is a miniature power relay that has been officially discontinued by Omron. The manufacturer’s recommended replacement is the MY4N-GS-R AC220/240. This upgraded “R” series model is a direct functional “drop-in” replacement, meaning it shares the same physical dimensions, 14-pin plug-in configuration, and electrical compatibility as the original version. You do not need to change your existing wiring or socket to switch to this model.
