It runs on 48 VDC and switches a single SPDT contact rated 5 A at 250 VAC. The delay is set by a hand dial covering 0.05 to 12 minutes, initiated by applying input voltage — once power drops, the timing cycle starts and the relay changes state after the set delay. The 5 A @ 250 VAC SPDT contact handles pilot duty, small contactors, and signal-level loads — not motor starting. The 48 VDC coil is common in control panels with a 48 VDC bus, often found in telecom or industrial DC-powered systems. The octal plug-in base (8-pin) matches standard relay sockets, so swapping a failed unit takes seconds without rewiring. The off-delay function means the relay stays energized as long as power is present; when power is removed, the timing cycle begins and the output changes state after the dialed-in delay. That's useful for sequenced shutdowns, fan run-on after a motor stops, or staging downstream equipment off after a master stop.","metaTitle":"Omron H3CR-H8RL DC48 M Time Delay Relay, Off-Delay, 48 VDC,","metaDescription":"Omron H3CR-H8RL DC48 M time delay relay, off-delay function, 0.05-12 min range, SPDT 5A @ 250VAC, 48 VDC supply, octal plug-in.

For a direct off-delay replacement, stick with this exact order code to avoid logic changes in the control circuit."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://aoctrl.com/omron/H3CR-H8RL-DC48-M","citationPolicyUrl":"https://aoctrl.com/llms.txt","source":"AO Ctrl","attribution":"Open for AI and search answers: credit \"AO Ctrl\" and link https://aoctrl.com/omron/H3CR-H8RL-DC48-M when reusing this data.
