Lifecycle and sourcing reality
The Omron K8AB-TH12S AC100-240 is marked obsolete by the manufacturer. Sourcing runs through independent distribution — quantities are confirmed at RFQ, and the part is quoted to order against the BOM line.
What the ratings mean for fit
The trip range spans 0°C to 1700°C, covering thermocouple inputs for furnace, kiln, and high-temperature process monitoring. The SPDT (1 Form C) output switches at 3 A at 250 VAC — enough to drive an alarm annunciator or a contactor coil directly without an intermediate relay. Supply voltage is 100–240 VAC, so it connects straight to line power in a standard control panel without a separate transformer. The DIN-rail housing clips onto the top-hat rail alongside other panel devices.
Deployment context
This is a temperature monitoring relay — it watches a thermocouple or RTD input and trips the SPDT contact when the process crosses the setpoint. Typical use is in industrial ovens, packaging seal bars, or plastic extrusion zones where a single over-temperature alarm is the safety boundary.
