The Yokogawa UD1BG3-045L-010102 is a specific model from the UTAdvanced series, functioning as a Line-Powered Signal Conditioner and Isolator.
This unit is designed to accept a DC Voltage input signal (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, protect against electrical noise, and ensure signal integrity. It then converts this isolated signal into a standard 4-20 mA DC analog current output, which is the industry-standard signal for transmission to control systems, PLCs, recorders, or indicators.

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.

This instrument is a Yokogawa UM1 series strip chart recorder, model UM1LG3-310B-1AA-2SA-N, designed for accurate recording of process variables on moving chart paper. It is widely used in industrial process control and laboratory data acquisition applications.

The UM1LG3-310B-1AA-1SA-Z is a high-precision direct-drive linear servo actuator / drive module (LINEARSERV series) from Yokogawa. It combines servo motor + linear actuator (slider) plus head amp / drive in an integrated unit. Designed for applications demanding excellent position accuracy, minimal backlash, and high dynamic performance (motion control, semiconductor equipment, precision assembly, etc.). The suffixes indicate feedback/encoder type (“1AA-1SA”) and connector/option/version (“Z”).

The UD1BG3-060N-1KC-2SB-N is a Direct-Drive Servo Actuator / Intelligent Drive unit in Yokogawa’s DrvGIII / DYNASERV / BG3 series. It is designed for high-precision motion control, providing torque, position and velocity control without the need for mechanical transmission elements (gears, belts), enabling high responsiveness, low backlash, and high accuracy. The “060N” indicates a certain torque / size class; “1KC-2SB” denotes specific feedback (encoder or resolver), input/output connector and internal configuration; “N” likely indicates standard version or region.

The UM1LG3-230C-1AA-2SA-N is part of Yokogawa’s LINEARSERV series, which are high-precision linear servo actuator and drive combinations. It is designed to provide accurate, direct-drive linear motion with high positioning resolution, no mechanical backlash, and fast response. These systems are typically used in semiconductor manufacturing, precision assembly, and other high-performance automation applications.

YOKOGAWAe UD1CG3-004N-1AA-2SA-N/CNIt is designed to drive a direct-drive servo motor (zero backlash, high precision), with high control fidelity. It supports auto-tuning, precise servo control, and is used in applications requiring high torque, precise position, or velocity control, e.g. in robotics, semiconductor equipment, precision assembly, motion control, etc.
The suffixes in the model name define options such as input voltage code, feedback or encoder type, braking or safety features, connector types, etc. The "CN" likely indicates “China / Chinese region / connector variant” or similar regional option.
