1. PT Series Core Model List (With Product Descriptions)

2. Quick Interpretation of PT Series Model Naming Rules

Mastering the naming logic can help you quickly identify the core parameters and applicable scenarios of the product:

1. Series Prefix: PT = Phoenix dedicated industrial control component series, focusing on circuit control, signal transmission and equipment protection.
2. Core Specification & Channel Configuration:
   • 4/3/2: Core current-carrying specification parameters of the component. The larger the value, the stronger the current-bearing capacity, suitable for high/medium/low load circuit scenarios respectively.
   • 2X1/1X2: Channel configuration codes. 2X1 means 2 groups of single-channel parallel control; 1X2 means 1 group of dual-channel synchronous control, adapting to different circuit grouping requirements.
   • 2+1: Special channel configuration, representing 2 main channels + 1 auxiliary channel, suitable for multi-signal collaborative control scenarios.
3. Function Suffix Mark:
   • PE/S: Protection grounding function, enhancing the electrical safety of the circuit, suitable for equipment with grounding requirements.
   • F: Enhanced control function, improving control precision and stability, ideal for high-demand circuit scenarios.
   • HF: High-frequency signal adaptation function, designed for high-frequency circuit control scenarios such as communication and sensors.
   • TELE: Telecommunication signal adaptation function, suitable for industrial communication system circuit connection.
   • IT: Fault indication function, providing real-time circuit status feedback, facilitating quick troubleshooting.
   • PB: Universal function configuration, compatible with multiple signal types and connection modes.
   • 1R2: Precise parameter matching code, tailored for specific circuit impedance matching requirements.
4. Voltage & Installation Specification:
   • Voltage codes (230AC/120AC/60AC/24AC/48DC/24DC/12DC/5DC): Represent the rated working voltage of the component, covering AC and DC voltage systems to match different industrial power supplies.
   • ST: Standard installation structure, compatible with Phoenix standard mounting rails and accessories, facilitating quick assembly and replacement.
   • BE: Basic installation structure, compact design, suitable for space-limited installation environments.
5. Certification Mark:
   • FM: FM safety certification, complying with international industrial safety standards, suitable for export-oriented equipment or high-safety-requirement scenarios.

4. Product Selection Suggestions

1. Specification & Channel Matching
   • Determine the current load requirements first: select 4-spec models for high-power main circuits; choose 3-spec models for medium-load control circuits; adopt 2-spec models for low-load signal circuits.
   • For multi-circuit control: select 2X1 models for dual-group single-channel parallel control; choose 1X2 models for single-group dual-channel synchronous control; adopt 2+1 models for main-auxiliary signal collaborative control.
2. Function Selection Based on Scenarios
   • For circuits with grounding requirements: Prioritize models with PE/S suffix.
   • For high-precision control scenarios: Select models with F enhanced function suffix.
   • For high-frequency/communication signal control: Choose models with HF/TELE suffix.
   • For critical circuit monitoring: Adopt models with IT fault indication suffix.
3. Voltage & Installation Matching
   • Match the component's working voltage with the on-site power supply system to ensure stable operation of the circuit.
   • For compact installation environments: Select BE basic structure models; for standard control cabinet installation: Choose ST standard structure models for better compatibility.
4. Certification & Cost Optimization
   • For export-oriented equipment or high-safety-requirement scenarios: Select FM certified models.
   • For general non-critical circuits: Choose basic structure models without additional function suffixes to reduce procurement costs.
