It packages five timing modes into one device — ON-Delay, Interval, One-Shot, Flicker ON Start, and the fifth function the H3CR-A series is known for — so one timer can replace several dedicated units on a control schematic. Time range runs from 0.05 s up to 300 h on a single dial, which covers anything from a fast conveyor-brake pulse to a multi-day process cycle without swapping the unit. Operating voltage spans 100 V to 240 V on the same coil, so the same part number drops into 110 V and 230 V panel builds without re-specifying the timer. ## Contact rating and what it will actually switch Output is a single changeover (1CO) contact rated 5 A switching current, 250 V AC or 30 V DC, with a switching power ceiling of 1.25 kVA on the AC side and 150 W on DC. That makes it a comfortable fit for small contactor coils, solenoid valves, and indicator lamps on a control panel — well clear of the 5 A ceiling — but not a candidate for directly switching heater loads or motor starters where the inrush sits above the rated contact figure. ## Mounting, sealing, and field handling Termination is via an 8-pin round socket, the standard H3CR-A base pattern, so a swap in the field is a pull-and-replace against the existing receptacle — no re-wiring required. Front-panel protection is rated IP40, which keeps finger contact and tool intrusion out of the dial and the output indicator, but it does not cover washdown or outdoor exposure; this timer belongs inside an enclosure, not on the cabinet door of a wet-process line. ## Where the H3CRA8EAC100240DC100OMI fits in a real control circuit Multi-function timers like this one typically sit between a sensor or pushbutton and the coil of a downstream contactor or solenoid — the dial sets the delay, the mode selector picks ON-Delay for a start-up timer, Interval for a fixed-run pulse, or One-Shot for a debounced single trigger. The 1CO contact can drive the coil directly up to 5 A, or feed an interposing relay if the load sits above the timer's contact rating.","metaTitle":"Omron H3CR-A timer, H3CRA8EAC100240DC100OMI, 8-pin, 5 A","metaDescription":"Omron H3CRA8EAC100240DC100OMI multi-function timer, H3CR-A series, 8-pin socket, 100-240 V, 5 A, 1CO, 0.05 s-300 h.","metaKeywords":null},"attributes":{"series":null,"packageCase":null,"mountingType":null,"rohsStatus":null,"productStatus":null,"categoryPath":["Electronic Timers & Counters"],"specifications":{"title":"H3CRA8EAC100240DC100OMI","Series":"H3CR-A","description":"Time Lag Relay 240V 1.25kVA 1CO 8-Pin Socket 300h H3CR-A IP40","lifecycle_stage":"mature","Termination Type":"8-Pin Socket","Mode of Operation":"Flicker ON Start;Interval;ON-Delay;One Shot Output","Protection Rating":"IP40","Time Setting Max.":"300 h","Time Setting Min.":"0.05 s","Number of Functions":"5","Switching Power - AC":"1.25 kVA","Switching Power - DC":"150 W","Contact Configuration":"1CO","Operating Voltage Max.":"240 V","Operating Voltage Min.":"100 V","Switching Current - AC":"5 A","Switching Current - DC":"5 A","Switching Voltage - AC":"250 V","Switching Voltage - DC":"30 V"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$97.90","stockQuantity":0,"priceTiers":null},"links":{"datasheetUrl":"https://cdn.aoctrl.com/2ca1b6af23134adc5d6a48fbc798ffd3.pdf","sourceUrl":null},"ai":{"faq":[{"question":"Who supplies the H3CRA8EAC100240DC100OMI and how is it quoted for volume purchases?","answer":"This timer is sourced to order through independent industrial-automation distribution, with pricing and current availability confirmed against an RFQ for the requested quantity.
