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

Step 1: Determine Module Series Based on Environment & Function

• Special harsh environments: MCR-FL series (e.g., outdoor, high-temperature, high-voltage) → 2864215, 2814838.
• Standard industrial scenarios: MCR-C series (general signal conversion) → 2810913, 2814537.
• Bus-based systems: MCR-ADC/DAC series (analog-digital conversion) → 2766931, 2808190.
• Multi-channel isolation: MCR-CLP series (1/2/4 channels) → 2814058, 2814045.
• High-reliability current processing: MCR-CPS/CPSS series → 2810900, 2814553.

Step 2: Confirm Input/Output Type & Voltage

• Input/Output Type:
  • Voltage-to-current (U→I): MCR-C-U-I-xxx (e.g., 2814537).
  • Current-to-voltage (I→U): MCR-C-I-U-xxx (e.g., 2814511).
  • Current-to-current (I→I): MCR-C-I-I-xxx or CLP/CPS series (e.g., 2814508, 2814016).
  • Voltage-to-voltage (U→U): MCR-C-U-U-DC (2814469).
  • Universal (U/I→U/I): MCR-C-UI-UI-xxx (e.g., 2810913).
• Power Supply:
  • 24V DC (automation systems): Most MCR-C/CLP models (e.g., 2814537).
  • 230V AC (mains power): MCR-FL-xxx-230 (e.g., 2864228).
  • Universal power (24/230AC/DC): MCR-FL-xxx-24/230 (e.g., 2814838).

Step 3: Select Special Requirements

• Channel Count: 1-channel (2814016) → single-signal; 2-channel (2810913) → dual-signal; 4-channel (2814537) → multi-signal; 8-channel (2766931) → bus-based multi-point monitoring.
• Non-contact Design: Cleanroom/high-safety scenarios → NC suffix (e.g., 2810939, 2814252).
• Bus Compatibility: BUS suffix (e.g., 2766931, 2808190) for DCS/PLC bus systems.
• High-Voltage Isolation: 450V isolation → 2810887 (for high-voltage environments).
• Custom Configuration: Need parameter adjustment → MCR/PI-CONF-WIN (2814799) software.

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

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

1. Input/Output Type Mismatch: PLC requiring current input using voltage-output modules → Confirm U-I (current output) or I-U (voltage output) in model (e.g., 2814537 for U→I).
2. Power Supply Error: 24DC system using 230AC models → Check power suffix (24/230/24/230) to avoid module burnout.
3. Channel Count Insufficiency: 4 sensors using 2-channel modules → Select 4-channel (2814537) or 8-channel (2766931) based on sensor quantity.
4. Special Environment Neglect: Harsh/outdoor environments using standard MCR-C models → Choose MCR-FL series (2864215) for enhanced stability.
5. Isolation Requirement Ignorance: High-interference environments using non-isolated modules → Select DCI/CLP isolation models (2810913, 2814016) to prevent signal distortion.
6. Bus Compatibility Oversight: Bus-based systems using non-BUS modules → Choose ADC/DAC BUS models (2766931) for seamless integration.
7. Non-Contact Need Neglect: Cleanroom applications using contact models → Select NC suffix (2810939) for non-contact signal processing.
