In mission-critical industrial applications such as semiconductor manufacturing, plastics extrusion, metallurgical heat treatment, and glass annealing, strict thermal stabilization is paramount to preventing structural defects and minimizing operational downtime. This controller utilizes an advanced 2-PID control algorithm with auto-tuning to achieve optimal thermal trajectories while suppressing overshoot. Equipped with a high-speed sampling loop of 60 milliseconds and high-resolution multi-inputs, the instrument ensures deterministic process control under highly dynamic thermal load variations.\u003c\/p\u003e\n\u003ch3\u003eControl Architecture \u0026amp; System Configuration\u003c\/h3\u003e\n\u003cp\u003eThe controller is engineered with a modular hardware configuration tailored for high-reliability process loops. It features a universal input stage that natively supports various thermocouple types (K, J, T, E, L, U, N, R, S, B, W, PL II), platinum resistance thermometers (Pt100, JPt100), and analog voltage\/current inputs (4-20 mA, 0-20 mA, 1-5 V, 0-5 V, 0-10 V). The control output block is configured with a voltage output (12 VDC) optimized for driving external Solid State Relays (SSRs) in high-cycling proportional control applications. To enhance localized safety interlocks, the architecture includes three independent auxiliary relay outputs for flexible alarm signaling. The \"-500\" suffix designates the inclusion of a terminal cover as a standard safety accessory, protecting field technicians from high-voltage terminal paths.\u003c\/p\u003e\n\u003ch3\u003eEquipment Specifications\u003c\/h3\u003e\n\u003ctable cellpadding=\"8\" cellspacing=\"0\" border=\"1\"\u003e\n\u003ctbody\u003e\n\u003ctr\u003e\n\u003cth\u003eParameter\u003c\/th\u003e\n\u003cth\u003eSpecification Details\u003c\/th\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eModel\u003c\/td\u003e\n\u003ctd\u003eE5AN-Q3MT-500-N\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eBrand\u003c\/td\u003e\n\u003ctd\u003eOMRON\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eOrigin\u003c\/td\u003e\n\u003ctd\u003eJapan\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eController Size\u003c\/td\u003e\n\u003ctd\u003e1\/4 DIN (96 mm x 96 mm x 78 mm)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eInput Type\u003c\/td\u003e\n\u003ctd\u003eUniversal Input (Thermocouple, Platinum RTD, Analog V\/mA)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eControl Output\u003c\/td\u003e\n\u003ctd\u003eVoltage Output for driving SSR (12 VDC, PNP, maximum 21 mA)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eAuxiliary Outputs\u003c\/td\u003e\n\u003ctd\u003e3 Relay Outputs (SPST-NO, 250 VAC, 3 A resistive load)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eSampling Period\u003c\/td\u003e\n\u003ctd\u003e60 ms\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eSupply Voltage\u003c\/td\u003e\n\u003ctd\u003e100 to 240 VAC, 50\/60 Hz\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003ePower Consumption\u003c\/td\u003e\n\u003ctd\u003e10 VA maximum\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eIndication Method\u003c\/td\u003e\n\u003ctd\u003e11-Segment Digital Display (PV: 15.8 mm, SV: 9.5 mm)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eTerminal Type\u003c\/td\u003e\n\u003ctd\u003eM3 Screw Terminals\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eWeight\u003c\/td\u003e\n\u003ctd\u003e0.31 kg\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eOperating Temperature\u003c\/td\u003e\n\u003ctd\u003e-10 to 55 deg C (with no icing or condensation)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003c\/tbody\u003e\n\u003c\/table\u003e\n\u003ch3\u003eHardware FAQs\u003c\/h3\u003e\n\u003cp\u003e\u003cstrong\u003eWhat is the functional difference between the older E5AN-Q3MT-500 and the \"-N\" version?\u003c\/strong\u003e\u003cbr\u003eThe \"-N\" designation indicates OMRON's upgraded series generation. It features an enhanced 60 ms sampling cycle (down from 250 ms), an upgraded 11-segment high-visibility display panel, and expanded advanced tuning parameters. It serves as a direct downward-compatible replacement for the legacy non-N models.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eCan the auxiliary relay outputs on this unit be configured as control outputs?\u003c\/strong\u003e\u003cbr\u003eNo. The primary loop regulation must be handled by the 12 VDC voltage output driving an SSR. The three auxiliary outputs are strictly software-mapped internal relays reserved for event alarms (e.g., upper\/lower limits, deviation, loop burnout) or basic logical interlocks.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eDoes this model require manual hardware jumpers to change from a K-type thermocouple to a Pt100 RTD sensor?\u003c\/strong\u003e\u003cbr\u003eNo hardware jumper changes are required. The input stage is fully universal. Field technicians simply modify the internal software parameter configuration via the front display panel or CX-Thermo software to change the sensor characteristics.\u003c\/p\u003e\n\u003ch3\u003eField Installation \u0026amp; Wiring Directives\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eEnclosure Cutout and Mounting:\u003c\/strong\u003e Prepare a standard 1\/4 DIN square panel cutout measuring 92 mm x 92 mm. Insert the controller through the panel front and secure it tightly from the rear using the provided mounting brackets. Tighten the fixing screws to a torque of 0.43 to 0.58 N-m to ensure a tight NEMA 4X\/IP66 front panel seal.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSensor Shielding and Input Separation:\u003c\/strong\u003e To minimize high-frequency noise corruption on low-voltage thermocouple or RTD inputs, run sensor cables through dedicated grounded metal conduits.

Observe correct polarity (Terminal 1 positive, Terminal 2 negative).
