The Yokogawa YF3INT-16 is an Electronic Totalizer (also called an Integrator) designed for use with Yokogawa's YF Series of Vortex Flowmeters. It is not a standalone device but a dedicated secondary electronic unit.

Its primary function is to receive the pulse output signal from a YF series vortex flowmeter (which is proportional to the flow rate) and calculate, display, and output the totalized flow. This means it continuously sums the flow over time to provide a reading of the total volume or mass of fluid that has passed through the meter.

The Yokogawa CP401-10 is a Signal Conditioner from the UTAdvanced series of DIN-rail mounted instruments. It is specifically designed as a Pulse (Frequency) to Analog Signal Converter.
Its primary function is to accept a pulse or frequency input signal from a field device (such as a turbine flowmeter, vortex flowmeter, or digital tachometer) and convert it into a standardized 4 to 20 mA DC analog output signal. This allows pulse-generating sensors to be easily integrated into process control systems, PLCs, or DCSs that expect a standard analog input.

The Yokogawa PW482-11 is a DC Power Supply Module designed for installation in Yokogawa's proprietary PLC (Programmable Logic Controller) or DCS (Distributed Control System) racks, such as those from the FA-M3 series.
It is part of a family of power supplies where the suffix number typically indicates the output current rating. The primary function of this module is to convert AC line power into a stable, well-regulated, and isolated 5V DC output used to power the backplane of the PLC rack. This backplane power is essential for operating the system's CPU module, I/O modules, and communication modules.

The Yokogawa SPW482-13 is a DC Power Supply Module designed for installation in Yokogawa's proprietary PLC (Programmable Logic Controller) or DCS (Distributed Control System) racks, such as those from the FA-M3 or other Yokogawa control families.

It is a specialized, high-power variant within the power supply lineup. Its primary function is to convert AC line power (typically 100-240V AC) into a stable, well-regulated, and isolated 5V DC output used to power the backplane of the PLC rack. This backplane power is essential for operating the system's CPU module, I/O modules, communication modules, and other internal components.

The Yokogawa PW482-50 S2 is a DC Power Supply Module designed for installation in Yokogawa's proprietary PLC (Programmable Logic Controller) or DCS (Distributed Control System) racks, such as those from the FA-M3 or other Yokogawa control families.

Its primary function is to convert AC line power (typically 100-240V AC) into a stable, well-regulated, and isolated 5V DC output used to power the backplane of the PLC rack. This backplane power is essential for operating the system's CPU module, I/O modules, communication modules, and other internal components.

The Yokogawa CP451-51 S2 is a Signal Conditioner from the UTAdvanced series of DIN-rail mounted instruments. It is specifically designed as a Pulse (Frequency) to Analog Signal Converter.
Its primary function is to accept a pulse or frequency input signal from a field device (such as a turbine flowmeter, vortex flowmeter, or digital tachometer) and convert it into a standardized 4 to 20 mA DC analog output signal. This allows pulse-generating sensors to be easily integrated into process control systems, PLCs, or DCSs that expect a standard analog input.

The Yokogawa S2CP471-01 is a Signal Conditioner from the S2 series of DIN-rail mounted instruments. It is specifically designed as a Pulse (Frequency) to Analog Signal Converter.
Its primary function is to accept a pulse or frequency input signal from a field device (such as a turbine flowmeter, vortex flowmeter, or digital tachometer) and convert it into a standardized 4 to 20 mA DC analog output signal. This allows pulse-generating sensors to be easily integrated into process control systems, PLCs, or DCSs that expect a standard analog input.

The Yokogawa AAI543-H53 is a Signal Conditioner from the UTAdvanced series of DIN-rail mounted instruments. It is specifically designed as a Dual-Channel Analog Isolator and Converter.
This model is a highly versatile module that accepts two independent 4 to 20 mA DC analog input signals from field transmitters. It provides electrical isolation between the input, output, and power supply circuits for each channel, and converts each input into a corresponding 1 to 5 V DC output signal.

The Yokogawa NFAI143-H50 is a Signal Conditioner from the UTAdvanced series of DIN-rail mounted instruments. It is specifically designed as a Dual-Channel Analog Input Isolator and Converter.
This model is a versatile module that accepts two independent 4 to 20 mA DC analog input signals from field transmitters (e.g., pressure, temperature, flow transmitters). It provides electrical isolation between the input, output, and power supply circuits for each channel, and converts each input into a corresponding 4 to 20 mA DC output signal.

The Yokogawa AAI543-H61 S1 is a Signal Conditioner from the UTAdvanced series of DIN-rail mounted instruments. It is specifically designed as a Dual-Channel Analog Isolator and Converter.

This model is a highly versatile module that accepts two independent 4 to 20 mA DC analog input signals from field transmitters (e.g., pressure, temperature, flow). It provides electrical isolation between the input, output, and power supply circuits for each channel, and converts each input into a corresponding 4 to 20 mA DC output signal.
