Core Features Current-to-Current (I-I) Signal Conversion for Industrial Precision: Functions as a high-accuracy industrial signal conditioner designed to convert and isolate 4–20mA (or 0–20mA) input current signals to standardized 4–20mA (or 0–20mA) output current signals. It ensures signal integrity with ±0.1% full-scale (FS) accuracy and ultra-low temperature drift (<50ppm/°C), making it ideal for transmitting precise measurement data (e.g., from sensors to PLCs) in noisy industrial environments. Galvanic Isolation for Noise Immunity: Integrates 3-port galvanic isolation (input-output-power, 2.5kVrms isolation voltage) to eliminate ground loops and block conducted noise between connected devices. This critical feature protects sensitive control systems (e.g., PLCs, DCS) from voltage spikes or interference caused by nearby heavy machinery, ensuring stable signal transmission in high-electromagnetic-interference (EMI) settings. Flexible Signal Configuration & Wide Compatibility: Supports customizable input/output signal ranges to match diverse industrial sensors and controllers: Input: 4–20mA DC, 0–20mA DC (selectable via DIP switches or software). Output: 4–20mA DC, 0–20mA DC (corresponding to input range, with linear scaling). Power supply: 24V DC (19.2–30V DC wide range), compatible with standard industrial 24V DC power systems. Industrial Durability & Reliable Operation: Built for harsh industrial environments, with an IP20 protection rating (IEC 60529) to shield internal components from dust and accidental contact. It operates reliably in temperatures from -25°C to +70°C, suitable for cold warehouses, warm production floors, or outdoor enclosures (with proper housing). Additionally, it resists vibration (10–500Hz, 50m/s² per IEC 60068-2-6) and shock (1000m/s² per IEC 60068-2-27), ensuring performance in high-vibration setups (e.g., manufacturing lines with heavy machinery). Compact Design & Easy Integration: Features a slim, DIN-rail mountable form factor (35mm standard DIN rail) with a width of only 12.5mm—optimized for space-constrained control cabinets. Tool-free screw terminal blocks enable quick, secure wiring (accepts 0.2–1.5mm² cables), and a green LED status indicator confirms power-on and normal operation—simplifying installation and troubleshooting for signal conditioning systems. Typical Applications The Phoenix Contact MCR-CP-I-I-00-2769585 is engineered for precise current signal conversion and isolation in industrial control systems—ideal for scenarios where signal accuracy and noise immunity are critical for measurement or control—with core use cases including: Sensor-to-PLC Signal Transmission: Converts and isolates 4–20mA signals from field sensors (e.g., pressure transducers, flow meters, temperature sensors) to standardized 4–20mA signals for PLCs (e.g., Siemens S7-1500, Allen-Bradley ControlLogix). The galvanic isolation eliminates ground loops, ensuring accurate data collection—complying with IEC 61298-2 standards for process measurement instruments. DCS System Signal Conditioning: Conditions 0–20mA signals from distributed sensors in large-scale Distributed Control Systems (DCS) (e.g., Emerson DeltaV, ABB 800xA). The high accuracy maintains linearity between sensor input and DCS output, critical for process control in chemical, oil, or pharmaceutical manufacturing—complying with IEC 61508 standards for functional safety. Heavy-Machinery Signal Isolation: Isolates current signals between sensors (e.g., load cells, proximity sensors) and controllers in high-EMI environments (e.g., automotive stamping plants, steel mills). The galvanic isolation blocks noise from welding machines or large motors, preventing signal distortion—complying with IEC 61000-6-2 standards for industrial EMI immunity. Remote Sensor Signal Boosting: Transmits 4–20mA signals from remote sensors (e.g., tank level sensors in oil refineries) over long distances (up to 1km) to central control systems. The conditioner maintains signal linearity and strength, avoiding signal degradation that occurs with direct long-distance wiring—complying with IEC 60870-5-1 standards for remote telecontrol systems.
