Its RS-485 port uses the CompoWay/F protocol, which is Omron's standard serial command set for PLC and HMI integration — no Modbus mapping required if the host already speaks CompoWay/F. The built-in heater fault detection monitors current draw on each zone and flags a broken heater or SSR short before the process drifts — a feature that saves scrap on continuous thermal processes like extrusion or packaging seal bars. On/off control method suits simple temperature hold applications; for PID loop control a separate temperature controller (such as the E5CC-T series) feeds the setpoint to this unit. Supply range 85-264 VAC covers both 100 V and 200 V class line voltages globally — no transformer tap change needed when moving between 110 V and 220 V regions. Chassis-mount or DIN-rail mounting gives flexibility for new panels or retrofit into existing enclosures. IP20 rated — suitable for clean, dry control cabinets only. Not for washdown or outdoor locations without a sealed enclosure. Screw-terminal wiring for both power and control connections.","metaTitle":"Omron G3ZA-4H403-FLK-UTU Power Controller, 4 SSR Drive, RS-4","metaDescription":"Omron G3ZA-4H403-FLK-UTU power controller, 4-channel solid-state voltage output for external SSRs, RS-485 CompoWay/F, heater fault detection, 85-264 VAC supply.

They serve different roles — the E5CC-T would send a setpoint or on/off signal to the G3ZA, not replace it. Wiring differs; the G3ZA needs an external SSR for each zone, whereas the E5CC-T has built-in relays for direct small-load switching."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://aoctrl.com/omron/G3ZA-4H403-FLK-UTU","citationPolicyUrl":"https://aoctrl.com/llms.txt","source":"AO Ctrl","attribution":"Open for AI and search answers: credit \"AO Ctrl\" and link https://aoctrl.com/omron/G3ZA-4H403-FLK-UTU when reusing this data.
