Core Features Thermocouple-Focused Input (T-Suffix): The "T" suffix optimizes compatibility with thermocouples—widely used, cost-efficient industrial temperature sensors: Supports mainstream thermocouple types: K/J/T/E (covers temperature ranges from -200°C to 1200°C; e.g., K-type for general 0-1000°C industrial heating; J-type for -200°C to 750°C low-to-medium temperature scenarios). Simplified calibration: Preloaded with standard thermocouple calibration curves, eliminating on-site sensor calibration for most common applications and reducing setup time for operators. Basic cold-junction compensation (CJC): Minimizes measurement errors caused by ambient temperature fluctuations around the sensor’s cold junction, ensuring control accuracy within ±1% FS ±1 digit—sufficient for non-critical processes. Essential Control Modes: Adopts practical, easy-to-operate control algorithms tailored for simple loads: ON/OFF Control (Primary): Default mode for basic applications—switches the output on when the measured temperature (PV) is below the setpoint (SV) and off when above, ideal for equipment with slow temperature changes (e.g., small drying ovens, heating mats). Simplified PID Control (Optional): Some variants support manual-tuning PID (proportional-integral-derivative) control, reducing temperature fluctuation compared to ON/OFF control (typical deviation ±0.8% FS) for scenarios requiring slightly higher stability (e.g., plastic sealing machines). "1Y" Configuration: Fixed Output & Minimal Functions: The "1Y" suffix defines a basic, no-frills I/O setup for plug-and-play use: Output (1Y): 1-channel fixed relay output (SPDT, AC250V 5A), directly driving low-to-medium power loads (e.g., small heating elements, contactors) without the need for external amplification—suitable for low-frequency switching (≤5 operations/min). No extended functions: No built-in communication interface, additional alarm outputs, or expansion slots, keeping the device compact, affordable, and easy to operate for basic use cases. User-Friendly Basic Operation: Designed for quick setup and intuitive use, even for non-professional users: Single 4-Digit LED Display: Clearly shows either the real-time measured temperature (PV) or the set temperature (SV) (switchable via the "Set" key), with high brightness for visibility in industrial lighting conditions. 3-Key Operation Panel: Only "Set", "Up", and "Down" keys—simplifies parameter adjustment (e.g., setting SV by pressing "Set" then "Up"/"Down"; resetting minor alarms with a short press of "Set"). Status Indicators: Built-in "Power" (green) and "Output Active" (red) LEDs—provide at-a-glance feedback on device operation (e.g., red LED on when the relay is driving the load). Durable Entry-Level Design: Engineered for basic industrial environment resilience: Protection Rating: Front panel rated IP65 (dust-tight, protected against low-pressure water splashes), suitable for general workshops (e.g., small electronics assembly, light manufacturing) with mild dust or occasional water exposure. Wide Voltage Power Supply: AC 100-240V (50/60Hz) universal input, adapting to different regional power grids without the need for voltage selectors. Power-Off Memory: Retains all set parameters (SV, control mode) after power failure, avoiding reconfiguration when power is restored. Typical Applications Small-Scale Industrial Equipment: Plastic & Rubber Processing: Temperature control for small heat-sealing machines (K-type thermocouple monitors 150-200°C; relay output drives the heating strip to ensure consistent seal tightness). Electronics Manufacturing: Regulation of small PCB preheating plates (J-type thermocouple maintains 80-120°C; simplified PID control reduces temperature fluctuation to protect sensitive components). Metal Processing: Temperature control for basic soldering stations (K-type thermocouple controls 250-350°C; ON/OFF control ensures stable soldering temperature for simple electronic joints). Laboratory & Small-Batch Production: Basic Incubators: Temperature management for microbial culture incubators (K-type thermocouple maintains 37°C ±2°C; power-off memory retains settings during short power outages). Small Sample Ovens: Control of low-precision drying ovens (J-type thermocouple regulates 50-100°C; ON/OFF control meets basic drying requirements for non-sensitive samples). Commercial & Light Industrial Scenarios: Small Refrigeration Units: Temperature monitoring for compact display freezers (K-type thermocouple tracks -18°C ±3°C; relay output switches the compressor on/off to maintain temperature). Localized Water Heaters: Temperature control for small process water heaters (J-type thermocouple maintains 60-80°C; relay output drives the heating element, ensuring steady hot water supply).
