The Yokogawa UR1BG3-045N-1KC-2TA-N is a Line-Powered (4-wire) Signal Conditioner and Isolator from Yokogawa's UTAdvanced series.
This sophisticated unit is designed to accept a DC Voltage input signal within a user-configurable range (e.g., from a sensor, transducer, or other voltage source). Its primary function is to provide electrical isolation between the input and output circuits to prevent ground loops and protect against electrical noise. It then performs a scaling conversion on this isolated signal.
