The Yokogawa UR1BG3-030A-020102-LZ-N/CN is a specific model of a Loop-Powered Signal Conditioner (also known as an Isolator or Interface Converter) from Yokogawa's high-density UTAdvanced series.

This unit is designed to accept a single 4-20 mA DC analog current input signal from a field transmitter (e.g., pressure, temperature, flow). Its primary function is to provide electrical isolation between the input and the output circuits to prevent ground loops, protect against electrical noise, and eliminate interference. It then generates two isolated and precise 4-20 mA DC output signals that are linear representations of the input signal.

The Yokogawa NFDV161-P00 Digital Input Module is an advanced industrial automation component designed to provide reliable data input for various control systems.

Yokogawa AAI143-H00 is an analog input module used in the CENTUM series distributed control systems. It receives analog signals from field transmitters, performs high-resolution A/D conversion, and transmits accurate digital data to the control processor. With robust isolation and stability, it ensures reliable acquisition of process variables in continuous industrial operations.
