Omron K8AC-H12PC-FLK Heater Burnout Detector 100-240VAC

Omron K8AC-H12PC-FLK is a heater burnout detector designed for monitoring heater circuits driven by solid-state relays (SSRs). It detects heater disconnections, element burnouts, or abnormal current flow in heating applications, ensuring preventive maintenance and system protection. Technical Specifications: Manufacturer: Omron Corporation Model: K8AC-H12PC-FLK Type: Heater burnout detector Power supply: 100–240 VAC, 50/60 Hz, 9 VA Primary current monitoring ranges (selectable models): – K8AC-H13PC-FLK: 0.2–22 A – K8AC-H22PC-FLK: 2–22 A – K8AC-H33PC-FLK: 70–200 A Inputs: Current transformer (CT) inputs (CT1, CT2 terminals) Outputs: Relay output (SPDT contact) for alarm indication Relay contact rating: 250 VAC, 5 A (resistive), 30 VDC, 1 A Response time: Typically ≤100 ms for fault detection Communication: RS-485 Modbus (A/B terminals for integration into monitoring systems) Indicators: – RUN (operation status) – ADJ (adjustment mode) – SET (set value confirmation) – GATE (synchronization with SSR gate signal) – SSR (solid-state relay status) – ALM (alarm status, fault detected) Front panel controls: Digital display with UP, DOWN, SHIFT, MODE keys for parameter adjustment Mounting: DIN-rail mountable housing (compact industrial enclosure) Operating temperature: -10°C to +55°C Storage temperature: -25°C to +65°C Humidity: 25% to 85% RH (non-condensing) Applications: Plastic molding machines, semiconductor equipment, packaging heaters, drying ovens, and other heater-driven systems Manufacture location: Japan (Omron production facilities) Please review pictures carefully and let us know if you have any questions!
