Product Overview

The Phoenix Contact MINI MCR-2-UNI-UI-2UI​ is a two-channel signal conditioner and isolating transmitter​ designed for industrial measurement and control applications. This module accepts universal analog inputs​ (voltage or current) and provides two-wire transmitter supply (2UI)​ for connected sensors. The module operates on 24V DC, provides galvanic isolation​ between input and output, and is mounted on DIN rail. The "MINI MCR-2-UNI-UI-2UI" designation specifies a 2-channel universal input conditioner with 2-wire transmitter supply. This device protects control systems from interference and provides signal conversion for sensors in harsh industrial environments.

Technical Specifications

Note: Specifications are based on Phoenix Contact MINI MCR series documentation. The "2-UNI-UI-2UI" suffix indicates 2-channel universal input with 2-wire transmitter supply. Always verify with the specific product datasheet.

Important Technical Notes

1. Power Supply:​ Requires 24V DC power (20.4-28.8V DC). Ensure adequate current capacity for all connected transmitters.

2. Input Configuration:​ Set input type (voltage/current) and range using DIP switches on the module before applying power.

3. 2-Wire Transmitter Connection:​ Connect the transmitter between output+ and output- terminals. The module supplies power to the transmitter through these terminals.

4. Load Limitation:​ Each channel can supply up to 25 mA. Ensure the connected 2-wire transmitter's current consumption is within this limit.

5. Isolation:​ Provides 1.5 kV isolation between input, output, and power supply. Maintain proper creepage and clearance distances in panel design.

6. Wiring:​ Use twisted pair or shielded cable for analog signals. Ground the shield at one end only (typically at the controller end).

7. Environmental Conditions:​ While rated for -20°C to +60°C, performance is optimized at room temperature. Derating may be required at temperature extremes.

8. Certifications:​ The module carries ATEX/IECEx certifications for hazardous areas. Follow all installation requirements for certified applications.
