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 protection.
2. Specification & Channel Configuration:
   • 4X1/2X2/1X2: Multi-channel configuration codes, representing 4 groups of single-channel, 2 groups of dual-channel and 1 group of dual-channel respectively, determining the circuit control quantity.
   • 5/4/2: Core specification parameters of the component, determining the current-carrying capacity and signal adaptation range of the product.
3. Function Suffix Mark:
   • BE: Basic structure type, standard configuration, suitable for general control scenarios.
   • FM: FM safety certification mark, complying with international industrial safety standards, suitable for export-oriented or high-safety-requirement equipment.
   • PE/S: Protection grounding function, enhancing the electrical safety of the circuit, suitable for equipment with grounding requirements.
   • HF: High-frequency signal adaptation function, designed for high-frequency circuit control scenarios.
   • EX(I): Explosion-proof grade with fault indicator, suitable for hazardous industrial environments with flammable and explosive risks.
   • +F: Enhanced function configuration, improving control precision and stability, suitable for high-demand control scenarios.
   • ST: Standard installation structure, compatible with Phoenix standard mounting rails and accessories, facilitating quick assembly.
4. Working Voltage Specification:
   • The voltage value in the model (24AC/24DC/12DC/5DC/48DC) represents the rated working voltage of the component, covering AC and DC voltage systems to match different industrial power supplies.

3. Core Advantages of Phoenix PT Series Components

1. Diversified Channel & Specification ConfigurationCovers multi-channel configurations (4X1/2X2/1X2) and core specifications (5/4/2), meeting the control needs of single-signal, multi-signal parallel and group synchronous control scenarios in industrial systems.
2. Wide Voltage Adaptation RangeSupports working voltages from 5V DC to 48V DC and 24V AC, matching low-voltage micro-signal circuits, mainstream industrial 24V systems and medium-voltage control circuits, with strong versatility.
3. Rich Extended Function SupportIntegrates protection grounding (PE/S), high-frequency adaptation (HF), explosion-proof (EX(I)), safety certification (FM) and enhanced control (+F) functions, adapting to complex industrial application scenarios.
4. Strong Compatibility & Easy InstallationThe ST standard installation structure is compatible with Phoenix's mounting rails and accessories, occupying small space in the control cabinet, suitable for dense wiring environments, and realizing quick plug-in and replacement.
5. Industrial-grade Reliable PerformancePasses strict high-temperature, high-humidity and vibration resistance tests, with stable operation in harsh industrial environments, ensuring long-term reliable work of the control system.

4. Product Selection Suggestions

1. Channel & Specification MatchingDetermine the number of controlled circuits and current load requirements first: select 4X1/2X2 multi-channel models for multi-circuit parallel control; choose 5-spec models for high-current control scenarios; select 2-spec models for micro-signal circuits.
2. Function Selection Based on Scenarios
   • For hazardous environments: Prioritize models with EX(I) explosion-proof suffix.
   • For high-frequency signal control: Select models with HF suffix.
   • For circuits with grounding requirements: Choose models with PE/S protection grounding function.
   • For export or high-safety-requirement scenarios: Select models with FM certification.
   • For high-precision control needs: Adopt models with +F enhanced function.
3. Voltage Adaptation ConfirmationMatch the component's working voltage with the on-site power supply system: select DC voltage models (24DC/12DC/5DC) for DC control systems; choose AC voltage models (24AC) for AC circuit control scenarios.
4. Installation & Cost OptimizationFor compact control cabinets: Select models with ST standard installation structure for space-saving; for general non-critical circuits: Choose basic BE structure models without additional functions to reduce procurement costs.
