UR1BG3-030-010102A4/CN/Z

The Yokogawa UR1BG3-030-010102A4/CN/Z is a highly advanced Single-Input Intelligent Signal Conditioner from the Yokogawa UTAdvanced series.
This "smart" DIN-rail mounted unit is designed for complex signal processing and distribution applications. It provides high-performance electrical isolation, signal conversion, and advanced mathematical computation. The complex suffix code defines its precise configuration: it is set up to accept a 4-20 mA DC current input signal, perform a Square Root (SQRT) extraction function on it, and produce two independent, isolated 4-20 mA analog outputs based on the result. The /CN/Z suffix indicates this is a standard production model (/Z) intended for the People's Republic of China market (/CN).
