Its 2CO (two changeover) contact set lets one unit drive two independent timed outputs from the same trigger — common where a sequence needs both a delayed pickup and a delayed drop, or where one timer feeds two downstream loads (solenoid + indicator, contactor + alarm) from a single start signal. Multifunction mode means the same device covers on-delay, off-delay, interval, repeat-cycle and similar timing patterns selected by dial — no spare SKU per mode, which trims panel-builder inventory when the same timer is used across different machines on the same line. ## Timing envelope and supply range Timing window runs from 0.05 s on the short end up to 300 h on the long end. That six-decade span covers everything from a sub-second pulse-stretch or debounce on a sensor input to a multi-day process interval (sterilisation hold, curing soak, seasonal drain cycling) — the dial position selects the range, and the fine adjust sits within it. At the top end, 300 h is roughly twelve and a half days, which is the ceiling the integrator needs to budget for when sizing long-tail batching or maintenance-interval reminders. Operating voltage spans 12 V minimum to 48 V maximum, so it accepts the common 24 VDC control rail directly and also drops into 12 V systems without a separate supply, while 48 V covers higher-voltage DC battery or DC-bus-derived rails. There is no AC coil variant in the listed spec — this SKU is DC-control only, which matters when a panel mixes legacy AC timers with newer DC logic: an AC-fed coil on this base will not pull. ## Wiring and panel-side fit Plug-in terminal termination means the timer body lifts out of its base socket without disturbing the wiring — swap-out on a live fault is a matter of releasing the latch and seating the replacement, not ringing out a rewire. The socket is the part that takes the panel screw-downs or push-in spring connections; the timer itself is the consumable. For a breakdown contractor that ordering discipline matters: keep a spare timer on the van, not a spare socket, because the socket rarely fails first. ## Lifecycle and supply posture No official successor or pin-compatible cross-reference is listed for this exact order code, so if the panel position must be filled with a like-for-like device, the BOM reference stays on this MPN rather than a parametric substitute.","metaTitle":"Omron H3CRAAC2448DC1248OMI Timer, Multifunction","metaDescription":"Omron H3CRAAC2448DC1248OMI plug-in electronic timer, 2CO contacts, 12–48 V supply, timing window 0.05 s to 300 h.","metaKeywords":null},"attributes":{"series":null,"packageCase":null,"mountingType":null,"rohsStatus":null,"productStatus":null,"categoryPath":["Electronic Timers & Counters"],"specifications":{"title":"H3CRAAC2448DC1248OMI","description":"Time Lag Relay 48V 2CO Plug-In Terminal 300h","lifecycle_stage":"mature","Termination Type":"Plug-In Terminal","Mode of Operation":"Multifunction","Time Setting Max.":"300 h","Time Setting Min.":"0.05 s","Contact Configuration":"2CO","Operating Voltage Max.":"48 V","Operating Voltage Min.":"12 V"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$108.30 – $130.90","stockQuantity":0,"priceTiers":null},"links":{"datasheetUrl":"https://cdn.aoctrl.com/2ca1b6af23134adc5d6a48fbc798ffd3.pdf","sourceUrl":null},"ai":{"faq":[{"question":"Who supplies H3CRAAC2448DC1248OMI and how is it quoted for volume?","answer":"For volume panel-build lines the same channel covers repeat scheduling and MRO spare replenishment from the same SKU."},{"question":"What are the key ratings on H3CRAAC2448DC1248OMI?","answer":"Multifunction timing mode, timing range 0.05 s to 300 h, 2CO (two changeover) contact set, operating voltage 12 V to 48 V, plug-in terminal base.
