In process plants, a single sensor often needs to communicate with both a main controller and a separate monitoring unit. Directly connecting both devices can cause noise or uneven readings. The MINI MCR-BL-I-2I solves this by duplicating one 4–20 mA input into two identical outputs, each electrically isolated. This ensures the PLC and local display both receive the same stable measurement. By preventing cross-interference, it removes the need for installing extra sensors, reducing wiring complexity and maintenance costs while keeping measurements consistent across different control points.
Gas detectors are critical in hazardous areas, and their signals must reach safety systems as well as auxiliary alarms. Directly splitting the signal can compromise accuracy and potentially disturb the safety loop. With the MINI MCR-BL-I-2I, one detector output is safely duplicated into two isolated loops, keeping the integrity of the primary safety system intact. The second output can then be used for event logging or alarm activation without risk. Its isolation design and low transmission error make it a reliable safeguard in environments where compliance and quick detection are vital.
When flow meters measure liquids or gases for trade purposes, both supplier and customer often require the same measurement data. Installing two separate meters is costly and can introduce discrepancies. The MINI MCR-BL-I-2I enables one flow signal to be duplicated accurately, sending one output to process control and another to billing or verification systems. This guarantees both parties receive identical, trustworthy information. Its high precision and four-way isolation prevent drift or interference, ensuring fair and transparent measurement. This approach improves efficiency, saves installation expenses, and maintains confidence in the recorded flow values.
In large industrial facilities such as wastewater plants or power stations, sensors may be installed far from the control cabinet. Long cable runs expose signals to voltage drops, electromagnetic interference, and ground loops. By placing the MINI MCR-BL-I-2I near the sensor, the input signal is stabilized and safely duplicated into two isolated outputs. Each output maintains accuracy even when transmitted across extended wiring. Its protective design prevents noise from affecting downstream systems and ensures the control system receives consistent data. This is especially valuable in environments where real-time monitoring and reliability are critical for operations.
