The Yokogawa UT150 is a compact digital indicating controller designed for precise temperature and process control. With its 1/16 DIN size, the UT150 provides high reliability, fast response, and easy operation. The UT150-RN/RET variant is configured for reliable control applications with standard relay or retransmission outputs. Its compact design, bright LED display, and flexible I/O options make it suitable for a wide range of industrial temperature and process control systems.

The Yokogawa UT150-AL S5 is a Digital Indicating Controller from the UTAdvanced family, specifically designed for temperature control applications.
The key differentiator of this model is the "AL" in its type code, which signifies it is equipped with a built-in alarm function as a standard feature. The "S5" suffix indicates a specific configuration, typically related to the control output type (e.g., a relay output for driving heaters/contactors) and the power supply specification.

The Yokogawa UT150-VN is a Digital Indicating Controller from the UTAdvanced family. It is a versatile, compact, and user-friendly panel-mounted instrument designed for precise measurement, display, and control of process variables such as temperature, pressure, flow, and level.

The Yokogawa AMN11 is a Signal Conditioner / Isolator Module from the UTAdvanced series (also known as the UT55A series). It is specifically designed as a current-to-voltage converter.
Its primary function is to accept a standard DC current input signal (most commonly 4-20 mA DC) and convert it into a proportional, electrically isolated DC voltage output signal (e.g., 1-5V DC). This type of signal conversion is essential for interfacing devices that use different signal standards within a control system.

The Yokogawa AAM11 is a Signal Conditioner / Isolator Module belonging to the UTAdvanced series (also known as the UT55A series). It is specifically designed as a current-to-current isolator and converter with alarm functionality.

The Yokogawa ACM11 is a Signal Conditioner / Isolator Module from the UTAdvanced series (also marketed as the UT55A series). It is specifically designed as a current-to-current isolator and converter.

The Yokogawa AMN33 is a Signal Conditioner / Isolator Module belonging to the UTAdvanced series (also known as the UT55A series in some regions). It is a versatile and highly reliable module designed for signal interfacing in industrial process control systems.

The Yokogawa UP55A-020-11-00 is a Signal Conditioner / Isolator Module designed for use with Yokogawa's UTAdvanced and UT55A series signal conditioning systems.
Its primary function is to electrically isolate a standard 2-wire 4-20 mA DC input signal and convert it into an identical, isolated 4-20 mA DC output signal. This isolation is crucial for breaking ground loops, preventing noise interference, and protecting sensitive control system equipment from voltage surges or faults occurring in the field.

The Yokogawa AIP501 is an expansion / analog input / I/O / coupler module used in Yokogawa’s control systems such as CENTUM VP,Its role is to accept many analog inputs (voltage, current, RTD, thermocouple), or to act as a coupler in network / backplane connections (V-Net) for distributing input signals. It is used in industrial process control / monitoring environments.

The Yokogawa AIP502 is a V-Net Coupler Module (Style S1) used in Yokogawa’s CENTUM CS / CENTUM VP distributed control systems (DCS). Its purpose is to link/control communications between Field Control Units (FCUs) and other networked devices via the V-Net protocol. It acts as a bridge (“coupler”) for the V-Net network, enabling communication over Ethernet/other networks, facilitating high-speed, reliable data transfer within the control system. The unit is rack-mountable or module-mountable, designed for industrial environments.
