The Allen-Bradley RS-3HR Panel Mount Time Delay Relay is an industrial timer designed for control panels, delivering adjustable timing over a 0–3 hour range with a 120 V supply. As a panel-mount timing relay, it integrates into industrial automation circuits to provide a delayed output for sequencing, interlocks, or timed control functions. The RS-3HR represents a straightforward, repeatable time-delay solution within the Allen-Bradley RS lineup for applications requiring a defined delay window.
