Schneider Electric 9050CO1E Relay

Schneider Electric's Square D 9050CO1E Timer/Counter is a compact on-delay timing relay from the Harmony 9050 family, designed for plug-in installation in control panels. It provides a single timing output and uses a standard dial to set the delay, with related 9050 CO variants offered for different timing configurations. In industrial automation, it is used to sequence events, delay actions, or count occurrences in equipment such as machines and conveyors when paired with compatible Square D relays and sockets. The 9050 family encompasses multiple timing and counting options, enabling selection of a model that matches on-delay, off-delay, or counter requirements.
