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

Step 1: Determine Core Function & Signal Type

• Temperature measurement (PT100/thermocouple):
  • General temperature → MCR-PT100 series (e.g., 2810353);
  • High-temperature → MCR-SL-HT/FL-HT series (e.g., 2864516, 2864529);
  • Explosion-proof area → MCR-FL-EX series (e.g., 2864574).
• Current/voltage conversion: MCR-R/SL series (e.g., 2769653, 2864011).
• Signal distribution: MCR-SGA series (e.g., 5604058).
• Power supply: MCR-PS series (e.g., 2781877).
• Frequency signal: MCR-F series (e.g., 2814605).

Step 2: Confirm Input/Output & Power Requirements

• Input signal: PT100 → select "PT100" models; thermocouple → "T/TS" models; current → "I" models; voltage → "U" models.
• Output signal: Need 4-20mA → "I" suffix; 0-10V → "U" suffix; relay → "RA" suffix.
• Power supply: 24V DC (most automation systems) → "DC-24" models; universal power → no voltage suffix.

Step 3: Select Special Requirements

• Installation: Quick wiring → Push-in (SP suffix, e.g., 2814948); space-constrained → low-profile (LP suffix, e.g., 2864558).
• Explosion-proof: Hazardous areas (Zone 0/1/2) → "EX" suffix models (e.g., 2864574).
• Protection: High-interference environments → 4KV surge protection (e.g., 2814841).
• Configuration: Custom parameters → USB-configurable (MCR-PAC-T-USB, 2309000).

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

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

1. Explosion-proof misuse: Non-EX models used in hazardous areas → Only "EX" suffix models (2864574) are compliant with explosion-proof standards.
2. Signal mismatch: PT100 input using thermocouple models → Confirm "PT100" in model (e.g., 2814948) for temperature compatibility.
3. Power supply error: 24DC system using AC-powered models → Check "DC" suffix (e.g., 2814883) to avoid module burnout.
4. Space neglect: Compact cabinets using standard-profile models → Select LP suffix (2864558) for low-profile installation.
5. Interference ignoring: High-voltage environments using unprotected models → Choose 4KV surge protection (2814841) to prevent signal distortion.
6. Output type error: PLC requiring voltage input using current-output models → Match "U" (voltage) suffix (2810340) or add conversion module (2769653).

Conclusion: Select the Right MCR Module for Precise Signal Processing
