Product details

What this detector does on the line

The K8AC-H23PC-FLK is a dedicated heater element detector from Omron's K8AC-H series, built to monitor current draw on electric heaters and flag a fault when a heater burns out or the load drops below the set threshold. It covers a 20 ~ 200A input range, so it handles everything from a small single-phase immersion heater to a three-phase bank pulling close to 200A per leg. The relay output gives a dry contact for the PLC or alarm panel — no separate signal conditioner needed.

Mounting, wiring, and panel fit

Snaps onto a DIN rail — standard enclosure integration, no panel cut-out or screw holes to lay out. Powered from 85 ~ 264VAC, so it runs on any plant voltage from 100V to 240V without a transformer tap change.

Communications and display

RS-485 with Omron's CompoWay/F protocol — the 4-digit red LED shows the live current reading, and the serial link lets the PLC poll the value and the fault status without extra wiring.

Frequently asked questions

Does the K8AC-H23PC-FLK work with single-phase heaters?

Yes — the 20 ~ 200A input range covers single-phase loads. The detector monitors the current on one phase; for three-phase heaters you would typically use one detector per phase or a three-phase model if the series offers it.
