Its 2 ~ 22A input range covers the typical draw of multiple cartridge or band heaters in a single zone, and the two solid-state outputs can drive an alarm or trigger a PLC input directly. ## RS-485 monitoring and 85~264 VAC supply The unit communicates over RS-485 using the Omron CompoWay/F protocol, so it can report heater current values and alarm status back to a PLC or SCADA host without pulling a separate analog input for each zone. The 85 ~ 264 VAC supply range means it works on common global line voltages without a step-down transformer. A 4-digit red LED display shows the measured current in amperes, readable from a few metres across the panel.","metaTitle":"Omron K8AC-H22PN-FLK Heater Element Detector, 2~22A","metaDescription":"Active Omron K8AC-H22PN-FLK heater element detector. 2~22A input, RS-485 CompoWay/F, DIN rail, spring terminals.
