Phoenix MINI MCR Series: Compact Industrial Signal Conditioning & Conversion Modules - Selection Guide 

Product Overview

The Phoenix MINI MCR Series comprises ultra-compact signal conditioning, conversion, and interface modules designed for space-constrained industrial automation systems. Split into two core sub-series (MINI MCR-SL / MINI MCR-BL) and specialized variants (RTD/PT100 temperature signal processing, power supply, label accessories), these modules support analog/digital signal conversion, temperature measurement, power distribution, and isolation. Featuring flexible terminal options (plug-in/SP, fixed/NC), wide input/output compatibility, and a 6.2mm narrow design, they excel in sensor signal conditioning, PLC interface integration, and critical parameter monitoring—ideal for control cabinets, compact machinery, and process automation where space and reliability are paramount.

Core Technical Specifications (Universal)

Application Scenarios & Recommended Models

1. Temperature Measurement (PT100/RTD/TC)

• Requirement: PT100 sensor temperature signal→current output (low-power)

• Recommended Model: 2810609 (MINI MCR-BL-PT100-I-LP-NC)

• Key Reason: Low-power design saves energy; PT100 compatibility for industrial temperature monitoring

• Requirement: RTD sensor temperature→voltage/current conversion (fast wiring)

• Recommended Model: 2902850 (MINI MCR-RTD-UI-SP-NC)

• Key Reason: SP plug-in terminal for quick maintenance; UI signal flexibility

2. Signal Filtering & Noise Suppression

• Requirement: Noise-prone voltage/current signal conditioning (with status monitoring)
• Recommended Model: 2902962 (MINI MCR-SL-FM-RC-SP-NC)
• Key Reason: FM status indicator + RC filter; SP terminal for easy replacement

3. Compact Sensor Power Supply

• Requirement: 24V DC→5V DC low-power sensor power (space-constrained cabinet)
• Recommended Model: 2902823 (MINI MCR-SL-CVS-24-5-10-SP-NC)
• Key Reason: 6.2mm ultra-narrow design; 10mA output fits small sensors

4. Current Signal Conversion & Isolation

• Requirement: Dual-sensor current signal conditioning (fast wiring)

• Recommended Model: 2864781 (MINI MCR-SL-2CP-I-I-SP)

• Key Reason: 2-channel design saves space; SP plug-in terminal for quick deployment

• Requirement: Noise-free current signal transmission (isolation)

• Recommended Model: 2810463 (MINI MCR-BL-I-I)

• Key Reason: 3kV isolation eliminates interference; compact design for dense layouts

5. Voltage-to-Current Conversion (Multi-Channel)

• Requirement: 4-channel voltage→current signal conversion for multi-sensor systems
• Recommended Model: 2810492 (MINI MCR-BL-U-I-4)
• Key Reason: 4-channel density reduces cabinet space; reliable basic-line performance

Core Advantages

• Ultra-Compact Design: 6.2mm width (single-channel) maximizes dense cabinet utilization (up to 32 modules per meter of DIN rail)
• Dual Sub-Series Flexibility: SL (standard) and BL (basic) variants balance functionality and cost
• Flexible Terminal Options: SP (plug-in) for fast maintenance; NC (fixed) for secure wiring
• Wide Signal Compatibility: Supports voltage/current/RTD/PT100/TC signals for diverse sensors
• Industrial-Grade Reliability: 3kV isolation, -25℃~70℃ operating temperature, and ±0.1% conversion accuracy
• Integrated Functions: Filtering, isolation, power supply, and conversion in one module (reduces component count)
• Easy Integration: Direct compatibility with Phoenix I/O modules and mainstream PLC systems

Installation & Usage Notes

• Voltage Matching: Ensure supply voltage is 24V DC (19.2~28.8V); avoid overvoltage to prevent module damage
• Terminal Selection: Choose SP terminals for systems requiring frequent maintenance; NC terminals for vibration-prone environments
• Wiring Specifications: For NC terminals, strip wires to 7mm and tighten to 0.5~0.6Nm; use 0.14~2.5mm² conductors
• Sensor Compatibility: For PT100/TC/RTD models, verify sensor type (e.g., PT100 2/3-wire) and wiring configuration
• Mounting Spacing: Reserve ≥3mm between modules for heat dissipation (critical in dense layouts)
• Labeling: Use MINI MCR-DKL-LABEL (2810272) for clear identification in multi-module setups
• EMI Mitigation: Route signal lines away from power cables; use shielded cables for noise-prone environments
