In custody transfer processes where oil or gas is measured for trade, the accuracy of flow signals directly affects billing and compliance. Flow meters typically generate a single current loop, but both the seller and the buyer need the same information. By using this signal duplicator, the original input can be split into two identical outputs without losing precision. The built-in isolation ensures that electrical noise or grounding issues do not distort readings. As a result, both monitoring systems remain synchronized, helping reduce disputes and maintain regulatory compliance.
Large solar plants use numerous sensors to track voltage and current from panels, inverters, and storage systems. A signal duplicator enables one sensor signal to be delivered to both the local optimization controller and the remote SCADA system. This dual output design ensures accurate performance data is available for real-time adjustments while also maintaining long-term logging for efficiency analysis. Isolation prevents faults or surges in one system from damaging the other, while configurable ranges allow different equipment types to be supported without adding extra conversion hardware.
In water treatment facilities, precise dosing of chemicals depends on flow or pressure signals. These signals often need to be shared between a dosing controller, a safety alarm, and a backup recorder. The MINI MCR-2-UNI-UI-2UI makes this possible by offering two independent outputs from a single input. The ability to convert between voltage and current signals increases compatibility with both modern PLCs and older control equipment. Built-in monitoring features and clear diagnostic indicators also reduce troubleshooting time, ensuring safe and consistent water quality control.
Machine builders frequently face strict space limitations inside control cabinets, yet still require reliable duplication of sensor signals for multiple functions such as display, logging, and PLC input. With its narrow 6.2 mm housing, the signal duplicator fits easily into compact panels without sacrificing performance. Configurable settings allow the same unit to serve across different machine models, simplifying procurement and reducing design complexity. Reinforced isolation protects sensitive electronics from electrical noise and switching transients commonly present in factory environments, improving long-term system stability.
