The Yokogawa UP750-50 is a versatile Programmable Digital Panel Meter (digital indicator) designed for precise display of process variables. The "50" in the model number is a specific code that indicates this unit is pre-configured or optimized for AC voltage measurement.
Its primary function is to accept an AC voltage input signal, condition it, and display the true RMS value on a large, high-visibility display. It is commonly used to monitor the main power supply voltage in industrial control panels, electrical distribution systems, and on machinery.

The Yokogawa UP750-01 is a highly versatile Programmable Digital Panel Meter (also known as a digital indicator) designed for precise display of a wide range of industrial process signals.
Its core function is to accept an input signal from a sensor or transmitter, perform scaling and linearization if necessary, and present the measured value on a large, easy-to-read display. The "01" in the model number is a key identifier that typically signifies it is a base model with a standard, universal input capability, often pre-configured or most commonly used for basic DC voltage or current signals like 4-20 mA or 1-5V.

The Yokogawa UP750-51 is a highly versatile Programmable Digital Panel Meter designed for precise display and processing of a wide range of industrial signals.
Its core function is to accept an input signal from a sensor or transmitter, perform scaling, linearization, and other calculations, and then present the measured value on a large, easy-to-read display. The "51" in the model number is a key identifier that typically signifies it is pre-configured or particularly suited for a specific input type, most commonly AC Current when used with an external Current Transformer (CT).

The Yokogawa UT520-08 is a Dual-Digital Display Meter designed for simultaneous monitoring of two different process variables.
Its primary function is to accept two independent input signals from sensors or transmitters and display their values simultaneously on a single, compact dual-display unit. This is highly effective for applications where comparing or monitoring two related parameters is necessary, such as inlet/outlet temperature, pressure and temperature, or flow and total volume.

The Yokogawa UP750-51/Z+Z25 is not a single unit but a pre-configured system consisting of a Programmable Indicator/Controller and a corresponding current transformer (CT) sensor for electrical current measurement.

The Yokogawa VW3A4611 is an optional expansion board designed for the GA700 and A1000 series industrial AC inverters. This module provides additional analog input and output channels, significantly enhancing the flexibility and integration capabilities of the variable frequency drive (VFD) with external control systems.

The Yokogawa F3BU09-0N is a FOUNDATION Fieldbus (FF) Power Conditioner (PCD), commonly referred to as a "Terminator" or "Barrier". It is a critical component in a FOUNDATION Fieldbus H1 network infrastructure, designed to be installed inside a Fieldbus Power Supply or a related system cabinet.

The Yokogawa UT152-VN is a critical safety interface device. It is not just a signal converter but a certified safety barrier that protects industrial plants by ensuring signals to and from hazardous areas are energy-limited, thus preventing the risk of fire or explosion.

The Yokogawa UT155-VN is a repeater-type safety isolator. It is the preferred choice when the field device in the hazardous area has its own separate power source (4-wire configuration). Its role is to safely pass through and isolate the signal while maintaining the integrity of the intrinsic safety barrier.

The Yokogawa UT150-VN/AL/RES is a robust and reliable hardwired alarm and trip module. Its key differentiator is the manual reset (latching) function, making it indispensable for critical alarm and shutdown applications where an automatic return to normal operation without operator acknowledgment is unacceptable. It provides a simple, yet highly effective, layer of safety logic.
