Integrated RS-485 serial communication runs deterministic networks via Modbus-RTU or CompoWay\/F protocols, transmitting process variables and alarm flags directly to host PLC nodes. Non-volatile EEPROM memory ensures complete firmware flash compatibility, securing user calibration maps, PID settings, and communication baud rates across mains power loss events without requiring battery backup.\u003c\/p\u003e\n\u003ch3\u003ePackage Deliverables \u0026amp; Accessories\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003e1 x Omron E5CC-QX3A5M-003 Digital Temperature Controller\u003c\/li\u003e\n\u003cli\u003e1 x Flush Panel Mounting Adapter Bracket\u003c\/li\u003e\n\u003cli\u003e1 x Waterproof Front Panel Sealing Ring\u003c\/li\u003e\n\u003cli\u003e1 x Protective Rear Terminal Cover\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch3\u003eField Wiring \u0026amp; Mechanical Mounting Rules\u003c\/h3\u003e\n\u003ch4\u003ePanel Cutout \u0026amp; Ingress Sealing\u003c\/h4\u003e\n\u003cul\u003e\n\u003cli\u003ePrepare a standard 45 mm x 45 mm panel cutout; slip the rubber sealing ring over the front housing bezel before inserting into the door to maintain IP66 front-face sealing.\u003c\/li\u003e\n\u003cli\u003eSlide the panel mounting adapter from the rear of the unit until the ratcheting mechanisms seat tight against the interior panel face.\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eSignal \u0026amp; Power Terminal Connections\u003c\/h4\u003e\n\u003cul\u003e\n\u003cli\u003eConnect AC line supply and control loop wiring to the rear screw terminals using crimped M3 spades or ring lugs; tighten screws to a maximum torque of 0.5 N-m.\u003c\/li\u003e\n\u003cli\u003eRoute RS-485 serial communication lines and Current Transformer (CT) leads using shielded twisted-pair cables, bonding the outer braid shield to panel earth ground at one point only.\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch3\u003eFrequently Asked Questions\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003e\n\u003cp\u003eWhat signal drive type is generated by the QX output designation?\u003c\/p\u003e\n\u003cp\u003eThe QX output delivers a 12 VDC PNP voltage pulse rated up to 21 mA, designed specifically to drive external Solid State Relays (SSRs).\u003c\/p\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cp\u003eWhich serial communication protocols are supported over the RS-485 interface?\u003c\/p\u003e\n\u003cp\u003eThe option 003 hardware supports standard Modbus-RTU slave protocol as well as Omron proprietary CompoWay\/F serial communication protocols.\u003c\/p\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cp\u003eHow does the controller detect 3-phase heater burnout conditions?\u003c\/p\u003e\n\u003cp\u003eThe unit processes AC current inputs from two external Current Transformers (CTs) to monitor individual phase line currents during heater conduction cycles.\u003c\/p\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cp\u003eWhat sensor types can be terminated to the universal input terminals?\u003c\/p\u003e\n\u003cp\u003eThe input stage accepts standard thermocouples (K, J, T, E, R, S, B), Pt100 RTDs, linear 4-20 mA current loops, and 0-10 VDC voltage signals.\u003c\/p\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cp\u003eWhat relay rating is provided on the 3 auxiliary output contacts?\u003c\/p\u003e\n\u003cp\u003eThe three auxiliary relay outputs support switching resistive loads up to 250 VAC at 2 A using a single shared common line.\u003c\/p\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cp\u003eHow is configuration parameter data protected against power supply failure?\u003c\/p\u003e\n\u003cp\u003eSettings are written to internal EEPROM non-volatile memory, maintaining parameter retention indefinitely across complete AC line outages.\u003c\/p\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cp\u003eWhat is the loop update rate of the internal PID control calculation?\u003c\/p\u003e\n\u003cp\u003eThe instrument executes complete analog input sampling and PID algorithm processing at a fixed cycle rate of 50 ms.\u003c\/p\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cp\u003eWhat front panel ingress protection rating is achieved after installation?\u003c\/p\u003e\n\u003cp\u003eWhen mounted with the included rubber gasket, the front display bezel provides IP66 water-resistant and dust-tight protection.\u003c\/p\u003e\n\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"Omron","offers":[{"title":"Default Title","offer_id":47306646749357,"sku":"E5CC-QX3A5M-003","price":100.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0733\/1613\/9181\/files\/E5CC-QX3A5M-003-1.jpg?v=1789997632","url":"https:\/\/www.maxwellplc.com\/ga\/products\/e5cc-qx3a5m-003-omron-digital-temperature-controller-e5cc-series","provider":"Maxwell PLC Ltd","version":"1.0","type":"link"}
