FUJI Temperature Controller PXR5NAR1-8W000-C

Core Features 1. Universal Multi-Sensor Input (N-Suffix) The "N" suffix emphasizes broad input versatility, eliminating the need for sensor-specific controllers: Triple-Type Sensor Support: Thermocouples (K/J/T/R/S/B/E/N): Covering a wide temperature range of -200°C to 1800°C (e.g., K-type for general 0-1200°C industrial heating; S-type for 0-1700°C high-temperature furnace operations; B-type for 600-1800°C ultra-high-temperature metallurgical processes). RTDs (Pt100/JPt100, 2/3/4-wire): Suitable for high-precision low-to-medium temperature scenarios (-200°C to 600°C), such as laboratory refrigeration systems and pharmaceutical incubators. Analog Signals (4-20mA/0-10V): Enabling integration with external transmitters for hybrid process monitoring (e.g., simultaneous temperature and pressure detection in chemical batch reactors). Precision Signal Processing: Equipped with advanced cold-junction compensation (CJC) for thermocouples and linearization technology for RTDs, ensuring control accuracy within ±0.2% FS ±1 digit—critical for meeting ISO 9001 and other strict quality management standards. Auto-sensor recognition function: Automatically identifies the type of connected sensor (thermocouple/RTD/analog) and matches the corresponding calibration curve, reducing on-site setup time by approximately 30% for production lines with multiple types of equipment. 2. Adaptive Control Modes (A-Suffix) The "A" in "NAR1" denotes advanced adaptive control capabilities to handle complex thermal dynamics: Auto-Tuning PID with Feedforward: Analyzes the thermal characteristics of the load (such as thermal inertia and response lag) during startup, and optimizes the proportional (P), integral (I), and derivative (D) parameters in real time. The feedforward function can predict potential load changes (e.g., addition of raw materials in batch production) and pre-adjust the output, reducing temperature overshoot to ≤3% and stabilizing the temperature 25% faster than conventional PID control. Fuzzy-PID Hybrid Control: Combines the advantages of fuzzy logic (fast response to sudden load fluctuations, such as oven door openings or material feeding) and PID control (high precision in steady-state operation), ensuring that the temperature deviation is maintained within ±0.5% FS even in highly disturbed processes. Dual-Zone Coordination Control: Supports basic dual-zone temperature control through the auxiliary output, realizing synchronous regulation of two independent heating/cooling zones (e.g., left and right sections of a semiconductor diffusion furnace), which helps to improve the uniformity of temperature distribution. 3. "8W000" Configuration: Flexible Output & Streamlined Functionality The "8W000" suffix defines a practical I/O configuration tailored for industrial adaptability: Main Output (8): 1-channel configurable output that supports three common industrial actuation types: SSR (Solid-State Relay) Drive (DC 3-32V, 20mA max): Suitable for fast-response and low-noise control of precision heaters (e.g., semiconductor wafer stage heaters), enabling high-frequency switching (up to 100 cycles/min) to maintain tight temperature ranges. Relay Output (SPDT AC250V 5A): Used to drive high-power loads (e.g., heating elements of industrial ovens, contactors) in low-frequency switching scenarios (≤10 operations/min, typical for slow-heating equipment). Analog Current Output (4-20mA): For proportional control of variable-speed devices (e.g., inverter-driven cooling fans, proportional valves for heating/cooling media), adjusting the output linearly according to temperature deviations. Auxiliary Output (W): 1-channel dual-purpose output, configurable for: Secondary Control: Acting as a second output for dual-zone heating (e.g., controlling both main and auxiliary heaters of a small drying oven) or coordinating heating and cooling systems (e.g., using relays for heating and SSR drives for cooling). Alarm Signaling: Triggering alerts for critical faults (such as over-temperature, sensor open/short circuits, and heater overloads) to protect equipment and products, with dry contact outputs compatible with PLCs, buzzers, or emergency shutdown systems. No Pre-Installed Modules (000): A base model without built-in communication or additional alarm modules, but retains an expansion slot for optional RS-485 (Modbus RTU) modules to realize integration with PLCs, SCADA systems, or HMIs—meeting the needs of users for future system upgrades. 4. Rugged "C" Suffix Design for Harsh Environments The "C" suffix represents enhanced durability to withstand tough industrial conditions: Protection Rating: The front panel has an IP66 protection rating (dust-tight and protected against high-pressure water jets), while the rear terminals have an IP20 rating—suitable for wet and dusty workshops (e.g., food processing plants, chemical factories) or areas requiring frequent cleaning (e.g., pharmaceutical cleanrooms). Environmental Resilience: Operates stably in an ambient temperature range of -10°C to 55°C and a relative humidity range of 30%-85% (non-condensing), and can resist vibration (complying with IEC 60068-2-6, 10-55Hz, 0.35mm amplitude), ensuring reliable performance in unconditioned factory environments. EMC Compliance: Meets the requirements of IEC 61000-4 (including ESD, EFT, and surge protection), minimizing electromagnetic interference from nearby high-voltage equipment (e.g., motors, welders) and ensuring stable control performance. 5. User-Friendly Operation & Practical Functions Intuitive HMI: Dual 4-digit LED displays (green for real-time temperature/PV, red for set temperature/SV) that show both values simultaneously, eliminating the need for display switching and facilitating quick status checks. A 6-key tactile keypad with dedicated "one-touch auto-tuning" and "parameter copy" functions (for batch configuration of multiple controllers), and a 2-level password protection mechanism to prevent unauthorized modification of critical parameters (e.g., PID constants, alarm thresholds). Operational Reliability: Power-off memory function: Retains all parameters (set temperature, PID settings, I/O configurations) for at least 10 years without power supply, and automatically resumes operation according to pre-shutdown settings when power is restored, minimizing production downtime. Self-diagnostic function: Continuously monitors the status of sensors, outputs, and internal circuits, and triggers visual and electrical alarms in case of faults, helping maintenance personnel quickly locate and resolve problems.
