It is not a general-purpose temperature controller; it is a safety and process-integrity device for electric heaters in ovens, extruders, packaging seal bars, and similar thermal systems where a failed element means a cold joint and a scrap part. The input range spans 20 to 200 A, covering most single-phase and three-phase heater banks in industrial machinery. The output is a relay that can trigger an alarm or shut down the zone when a heater fault is detected. ## Fit and wiring constraints Termination is via spring terminals, not screw clamps. That means you need a ferrule on stranded wire and a small screwdriver to push the cage open — no torque driver required, but the wire strip length must be precise to bottom out in the cage. Powered from 85 to 264 VAC — universal line voltage for industrial control transformers, no separate 24 VDC supply needed for the detector itself. The four-digit red LED display shows the measured current value; the RS-485 port (CompoWay/F protocol) lets a PLC or SCADA poll the reading and the fault status. ## Sourcing reality — obsolete, not gone Omron has marked the K8AC-H23CC-FLK as obsolete. If the application can accommodate a panel-mount controller with heater fault detection built in, the Omron E5EC series (e.g., E5EC-RX4ABM-008) is a functional peer — it offers the same heater fault detection feature plus PID control, RS-485, and a tri-color LCD display, but it requires a panel cutout and does not mount on DIN rail.","metaTitle":"Omron K8AC-H23CC-FLK Heater Element Detector, 20-200A","metaDescription":"Omron K8AC-H23CC-FLK heater element detector, 20-200A input, RS-485 CompoWay/F, DIN rail mount.
