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.

The Yokogawa NFLR121-S00 is a Signal Converter / Isolator from the NFL series of DIN-rail mounted instruments. It is specifically designed as a RS-422 / RS-485 Serial Communication Line Receiver (Isolating Repeater).

The Yokogawa SSB401-13 S1 is a Signal Conditioner from the SSB series of DIN-rail mounted instruments. It is specifically designed as a Dual-Channel Isolator and Converter.
Its primary function is to accept two independent 4 to 20 mA DC analog input signals from field transmitters, provide electrical isolation, and convert each input into a corresponding 1 to 5 V DC output signal. This conversion is essential for interfacing with control system hardware (like some PLC or DCS cards) that require voltage inputs instead of current inputs.

The Yokogawa NFSB100-S00 is a Signal Conditioner from the NFS series of DIN-rail mounted instruments. It is specifically designed as a Dual-Channel Isolator and Converter.
Its primary function is to accept two independent 4 to 20 mA DC analog input signals from field transmitters (e.g., pressure, temperature, flow), provide electrical isolation between the input, output, and power supply circuits, and convert each input into a corresponding 4 to 20 mA DC output signal.
