Syracuse Electronics RBCA-30317 Relay

The Syracuse Electronics RBCA-30317 time-delay relay provides a fixed 180-second delay on a 115 VAC supply, a precise timing element commonly used to sequence startup steps in industrial automation and control panels. It uses an 11-pin plug-in base and plug-in socket mount, with electromechanical relay contacts rated at 9 A resistive at 115 VAC for reliable switching in motor control circuits and conveyor systems. Designed for fixed time-delay switching, the RBCA-30317 supports startup sequences, packaging machinery, and process equipment where delayed activation and orderly, sequential operation are required, and is manufactured in the United States. Common replacements include Omron H3CR timer relay, Schneider Electric Zelio timer relay, and Crouzet Chronos timer relay.
