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.","metaTitle":"Omron K8AC-H23PC-FLK Heater Element Detector, 20-200A","metaDescription":"Omron K8AC-H23PC-FLK heater element detector, 20-200A input, relay output, RS-485 CompoWay/F, DIN rail mount.
