Eaton Cutler-Hammer 8251B-6501 Time Delay Logic Module

The Eaton Cutler-Hammer 8251B-6501 Time Delay Logic Module is a SER.B1-series control device that provides delayed logic functionality for electrical control systems. Identified by part number 8251B-6501, this module serves as a dedicated timing element within industrial automation and panel-based control circuits, processing input signals to generate a timed output that helps coordinate sequencing and timed control actions. As part of the Cutler-Hammer family, it integrates with standard control architectures used in electrical panels and machinery, where deterministic timing of logic signals supports safe, orderly operation of equipment. In typical use, time delay logic modules help implement timing-dependent control actions and coordinate signals in automation schemes. The 8251B-6501 designation uniquely identifies this unit within Eaton’s SER.B1 lineup, distinguishing its role within the broader family of timing and logic modules.
