Active Heater Current Monitor for Panel Integration
The K8AC-H22PC-FLK is an active-production heater element detector from Omron's K8AC-H series, designed to monitor current draw of resistive heater loads and alarm on open-element or partial-fault conditions. Its input range of 2 ~ 22A covers most single- and three-phase heater strings in industrial ovens, packaging seal bars, and injection-molding nozzle heaters — the 4-digit red LED shows live current so a quick glance tells you if a zone dropped out. Mounts on standard DIN rail (35 mm) and terminates via spring-clamp terminals — no screwdriver needed for the field wiring, which matters when you're swapping a failed unit on a live panel and every second counts.
Communications and Supply — What Fits the Van
Built-in RS-485 with Omron's CompoWay/F protocol lets you poll the detector over a two-wire bus from a PLC or HMI — useful when the heater bank is on the far side of the plant and you want the alarm in the SCADA log, not just a local light. Universal AC supply 85 ~ 264 VAC means it runs on anything from a 110 V control transformer to a 240 V line without a jumper change — one part number for the whole panel build. Operating temperature -10°C to 55°C covers most indoor control cabinets; keep it out of direct steam washdown areas despite the DIN-rail form factor.
