It runs on a universal 24 VAC/DC supply, so it fits panels where only a low-voltage control transformer or DC bus is available — no need to pull a separate 100–240 VAC feed. The output stage gives you three relay outputs for on/off or alarm functions, one analog output for driving a valve or SCR power controller, and a voltage pulse output for an external SSR — enough flexibility to handle most single-loop heating or cooling applications without adding auxiliary modules. ## PID tuning and heater diagnostics built in Control method is selectable between On/Off and proportional-integral-derivative (PID) with auto-tuning, so you can start with a simple bang-bang loop and move to PID once the process is stable. The heater fault detection feature monitors current draw on the load and flags an alarm if the heater opens or degrades — a real time-saver when you're troubleshooting a mold or oven that's not reaching setpoint. RS-485 communications support both Omron's CompoWay/F protocol and standard Modbus, letting you pull PV, SV, and alarm status into a PLC or SCADA without a separate gateway. ## Panel fit and environmental sealing Mounts in a standard 45 mm x 45 mm square panel cutout — the same footprint as every other E5CC variant — so swapping between models doesn't require re-punching the panel. The front panel carries an IP66 rating, meaning it's dust-tight and protected against hose-directed water. That makes it suitable for food-processing or washdown zones where a standard IP20 controller would fail. It ships in bulk packaging, which is typical for OEM quantities; if you need individual boxes for MRO stock, confirm at quote time.","metaTitle":"Omron E5CC-CQ3D5M-003 Temperature Controller, 24V, PID","metaDescription":"Omron E5CC-CQ3D5M-003 process/temperature controller, 24VAC/DC, PID control, RS-485 Modbus, analog + 3 relay outputs, IP66 front panel.","metaKeywords":null},"attributes":{"series":null,"packageCase":null,"mountingType":null,"rohsStatus":null,"productStatus":"Active","categoryPath":["Process / Temperature Controllers"],"specifications":{"Type":"Process, Temperature Controller (RTD, Type B, E, J, K, L, N, PLII, R, S, T, U, W)","Series":"E5CC","Weight":"0.265 lb (120.2 g)","Package":"Bulk","Features":"Heater Fault Detection","Input Range":"-200°C ~ 2300°C, 0 ~ 20mA, 0 ~ 10VDC","Output Type":"Analog, Relay (3), Voltage (External SSR)","Display Type":"LCD - Dual Color Characters, Backlight","Mounting Type":"Panel Mount","Communications":"RS-485 (CompoWay/F, Modbus)","Control Method":"On/Off, Proportional (PID)","lifecycle_stage":"current","Voltage - Supply":"24VAC/DC","Termination Style":"Screw Terminal","Ingress Protection":"IP66 - Dust Tight, Water Resistant","Operating Temperature":"-10°C ~ 55°C","Panel Cutout Dimensions":"Square - 45.00mm x 45.00mm","Display Characters - Height":"0.600\" (15.20mm), 0.280\" (7.10mm)","Number of Characters Per Row":"4, 4"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":null,"priceTiers":null},"links":{"datasheetUrl":"https://cdn.aoctrl.com/c6d2565f7c49acd020a74c22dc4212b3.pdf","sourceUrl":null,"alternativesUrl":"https://aoctrl.com/api/mcp/products/E5CC-CQ3D5M-003/alternatives.json"},"ai":{"faq":[{"question":"What is the difference between the E5CC-CQ3D5M-003 and the E5CC-QX2DBM-002?","answer":"Both are E5CC-series controllers with the same input range, output count (analog + 3 relay + SSR drive), RS-485 communications, and 24 VAC/DC supply. The deciding difference is termination: the CQ3D5M-003 uses screw terminals, while the QX2DBM-002 uses spring-clamp terminals.
