Input range covers 2 to 22 A, so it catches the full operating band of most single-phase or three-phase heater strings in that amperage window. The 85 to 264 VAC supply means it runs off any standard line voltage without a separate control transformer — handy when you're pulling power straight from the heater contactor's feed. ## RS-485 and Relay Output RS-485 communication using Omron's CompoWay/F protocol lets a PLC or SCADA poll the detector for real-time current values and fault status — useful for logging heater life or triggering a pre-alarm before the line goes cold. The relay output gives a hard contact for direct alarm annunciation or a safety interlock. Four red LED characters display the measured current value locally, so a technician walking the panel can see at a glance which heater is drawing current and which one dropped out. On/Off control method means it's a threshold-based detector, not a PID loop — set the trip point and it flags when the current falls outside the window. ## Active Production, Sourced to Order","metaTitle":"Omron K8AC-H22CC-FLK Heater Element Detector, 2-22A","metaDescription":"Omron K8AC-H22CC-FLK heater element detector, 2-22A input range, 85-264VAC supply, RS-485 CompoWay/F, DIN rail mount.
