   • DIO: Digital input/output interface, with signal direction identification (R-L/L-R), suitable for industrial automation system connection.
   • 3L/L: Phase identification function, 3L is three-phase, L is single-phase, ensuring correct AC circuit wiring.
   • F/HEDI: Enhanced function, F improves control precision, HEDI realizes high-precision signal detection.
   • P/P: Dual polarity identification, suitable for dual-polarity circuit connection scenarios.
3. Appearance & Size Parameter
   • BU/OG/GY: Color coding, blue/orange/gray appearance facilitates quick circuit identification in complex wiring environments.
   • (6,3X32)/(5X20): Size of the status indicator module in millimeters, determining the installation compatibility with the terminal.
   • 120KOHM: Matching resistance parameter, tailored for high-precision circuit monitoring scenarios.

4. Product Selection Suggestions

1. Spec Matching According to Current Load
   • For high-power industrial main circuits (such as motor power supply): Select UT 6 series models.
   • For medium-load control and signal circuits (such as sensor connection): Choose UT 4 series models.
2. Channel Configuration Selection Based on Circuit Quantity
   • For multi-circuit parallel connection: Select TWIN dual-channel models for small-scale parallel; choose QUATTRO four-channel models for large-scale distribution.
   • For single-circuit or simple dual-circuit connection: Adopt basic UT 6/UT 4 models to reduce costs.
3. Function Selection Based on Scenario Requirements
   • For hazardous environment circuit monitoring: Prioritize models with EX explosion-proof suffix + HESILED/HESI status monitoring function.
   • For circuit safety requirements: Select models with PE protection grounding suffix.
   • For industrial automation digital control: Choose models with DIO digital interface suffix, and match the signal direction (R-L/L-R) according to the system requirements.
   • For three-phase AC circuit wiring: Select UT 6-3L model with three-phase identification function.
   • For dual-polarity circuit connection: Adopt models with P/P polarity identification suffix.
4. Identification & Cost Optimization
   • For complex wiring systems: Select color-coded models (BU/OG/GY) to improve maintenance efficiency.
   • For general non-critical circuits: Choose basic structure models without additional function suffixes (such as UT 6, UT 4) to reduce procurement costs.
