Phoenix MACX MCR/MCR-EX Series Selection Guide: Precise Matching of Part Number, Model, and Application

Opening: Efficient Industrial Signal Isolation Selection – One-Stop Part Number & Model Reference

In industrial scenarios such as petrochemicals, pharmaceuticals, energy, and intelligent manufacturing, the selection of signal isolators directly affects system stability, production safety, and compliance. As a core product line in the field of industrial signal conditioning, the Phoenix MACX MCR/MCR-EX series is widely used in various critical applications due to its advantages including explosion-proof certification, full signal compatibility, and high safety rating. This article integrates the part number-complete model correspondence of the entire series, combined with selection logic, application adaptation, and key points to avoid pitfalls, providing clear guidance for technical selection and procurement work, and helping to quickly lock in suitable solutions.

I. Core Advantages: Why Choose the MACX MCR Series?

• Comprehensive coverage of explosion-proof and general-purpose scenarios: The MCR-EX series (with "-EX-") holds Ex ia intrinsically safe certification, suitable for hazardous areas (Zone 0/1/2); the MCR series is designed for general areas.
• Full signal compatibility: Supports all signal types including current, temperature, frequency, and digital signals, with HART communication capability.
• Flexible installation: Offers Push-in quick connection (with "-SP" suffix) and screw connection (without suffix) to meet different installation requirements.
• High safety rating: SIL 2/3 certified, compliant with IEC 61508 standard, suitable for safety-critical systems.

II. Complete Product Series Selection Table (Part Number + Model + Core Information)

1. Current Signal Isolation Series (IDS) – Most Widely Used in Industry

2. Multi-Functional Signal Conditioning Series (AP) – All-Round Adaptation

3. Temperature Measurement-Specific Series (1TS/TC/CJC) – Precise Temperature Sensing

III. 3-Step Quick Selection Technique (Easy for Beginners)

Step 1: Determine the Scenario (Explosion-Proof/General-Purpose)

• Hazardous areas (Zone 0/1/2) → Select models with "-EX-" (e.g., 2908062, 1145207);
• General areas → Select models without "-EX-" (e.g., 1145196, 2924993).

Step 2: Lock in the Signal Type

• Current signals (4-20mA) → IDS series;
• Temperature signals (RTD/TC) → 1TS/AP series, thermocouples require CJC compensators;
• Frequency/digital signals → AP series (with "-F-" or "-REL-").

Step 3: Choose the Connection Method

• New projects/batch installation → Push-in (with "-SP" suffix, e.g., 2908062, 1292332);
• Renovation projects/vibrating environments → Screw connection (without "-SP", e.g., 2908060, 1292331).

IV. Recommended Industry-Scenario Combinations (Ready-to-Use)

V. Selection Pitfall Avoidance Guide (Common Mistakes to Note)

1. Forgetting to equip CJC compensators for thermocouple measurement → Must select 2925002 (explosion-proof areas) / 2924993 (general areas); otherwise, the error will exceed 5℃;
2. Selecting non "-EX-" models for hazardous areas → Violates explosion-proof regulations; prioritize the full MCR-EX series;
3. Choosing low-load models for long-distance transmission → Insist on the IDS series (load ≥700Ω) to avoid signal attenuation;
4. Using multiple single-channel models for multi-point measurement → Select dual-channel models (e.g., 2904931) to save 50% of space and costs.

Conclusion: Select the Right Model for Safe and Efficient Operations
