It operates on 24 VAC/DC and mounts directly to DIN rail, with an operating temperature range of -20°C to 60°C. The relay has no built-in delay — response is essentially instantaneous, which matters when you need rapid fault isolation in a temperature protection loop. The solid-state output (NPN circuit) sinks current rather than switching a dry contact, so plan for a pull-up resistor or match to a compatible PLC input module. DIN-rail enclosure; unit is packaged as a box (not a open-frame module). The 24 VAC/DC supply can share a common bus with other K8DT units — verify polarity consistency on DC if mixing supplies. Terminal identification follows Omron’s standard: check the profile drawing on the housing before landing wires.","metaTitle":"Omron K8DT-TH1TD Temperature Monitoring Relay, Solid State O","metaDescription":"Omron K8DT-TH1TD temperature monitoring relay, Series K8DT, NPN circuit, solid state output, 24VAC/DC supply, DIN rail mount, -20°C to 60°C operating range, active production.","metaKeywords":null},"attributes":{"series":null,"packageCase":null,"mountingType":null,"rohsStatus":null,"productStatus":"Active","categoryPath":["Process / Temperature Controllers"],"specifications":{"Type":"Temperature Monitoring","title":"K8DT-TH1TD","Series":"K8DT","Circuit":"NPN","Package":"Box","Delay Time":"No Delay","Output Type":"Solid State","description":"TEMP MONTRG TRNSTC/RTD PSH IN","Mounting Type":"DIN Rail","lifecycle_stage":"current","Voltage - Supply":"24VAC/DC","Operating Temperature":"-20°C ~ 60°C"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$181.35 – $187.07","stockQuantity":0,"priceTiers":null},"links":{"datasheetUrl":null,"sourceUrl":null},"ai":{"faq":[{"question":"What is the stated type and series of this part?","answer":"The type is Temperature Monitoring, and the series is K8DT.
