USED OMRON H3BG-8H

The Omron H3BG-8H is a solid-state analog star-delta timer designed for industrial motor starting applications, providing precise timed control of star-to-delta transition sequences. It mounts in a standard 8-pin octal plug-in socket (e.g., P2CF-08) and features both a time-limit output contact and an instantaneous contact output (the "8H" designation), giving it additional flexibility over the standard 8-pin model. This is a legacy Omron H3BG series product, now typically replaced by the H3CR-G series, but remains widely used for compatible motor starter panel applications.
