Heater Element Detector for 20 ~ 200A circuits
The K8AC-H13CC-FLK is a Heater Element Detector from Omron's K8AC-H series, designed to monitor heater current and detect faults like open elements or SSR shorts. It accepts an input range of 20 ~ 200A, making it suitable for larger heater loads in industrial ovens, injection molding machines, or packaging lines. The unit outputs a relay contact for alarm or control, and communicates via RS-485 using Omron's CompoWay/F protocol for integration with a PLC or SCADA system. Power supply is universal 85 ~ 264VAC, so it works on any standard line voltage without a separate transformer. The 4-digit red LED display shows the measured current value, and the On/Off control method allows simple threshold-based switching. Mounts on a DIN rail and uses screw terminals for wiring — no special tools needed for installation.
How it compares to the K8AC-H12PC-FLK
The closest functional peer is the K8AC-H12PC-FLK, which shares the same series, DIN rail mount, relay output, RS-485 communications, and 85 ~ 264VAC supply. The key difference is the input range: the H13CC-FLK covers 20 ~ 200A, while the H12PC-FLK covers 2 ~ 22A. If your heater current falls below 20A, the H12PC-FLK is a better fit; above 22A, only the H13CC-FLK (or a different series) will work. Both use screw terminals, so wiring is identical.
Installation notes
The unit is rated for operating temperatures from -10°C to 55°C, so it can live in a warm panel but not directly next to a heat source. The screw terminals accept standard stranded or solid wire; no ferrule required. The RS-485 bus uses CompoWay/F protocol — set the node address via the front panel. The relay output is rated for the load you connect; verify the contact rating against your alarm or control circuit.
