It accepts inputs from K, J, T, or E thermocouples as well as Pt100 or Pt1000 RTDs, making it a versatile single-point over-temperature or under-temperature detector for industrial control panels. The relay output is a single-pole double-throw (SPDT) contact rated 5 A at 250 VAC — enough to switch small heaters, cooling fans, alarms, or signal lamps directly without an interposing contactor. Supply voltage is 24 VAC/DC, so it runs from a common control transformer or DC power supply found in most cabinets. No delay timer is built in; it responds immediately to a temperature fault. Given its active status, lead times are typically short and the supply chain stable. ## Key ratings explained The SPDT contact rating of 5 A at 250 VAC is sufficient for most alarm circuits and light industrial loads. For higher loads, use the relay to pilot a contactor. Operating temperature range of -20°C to 55°C covers typical panel environments; note that the 55°C upper limit is the relay's ambient, not the process temperature being monitored — the sensor type determines process range.","metaTitle":"Omron K8AK-TH11S 24VAC/DC Temperature Monitoring Relay, SPDT","metaDescription":"Active production temperature monitoring relay by Omron.
