Yokogawa PH450G-AA/UM

Product Introduction: The PH450G-AA/UM is a 2-wire, loop-powered pH/ORP (oxidation-reduction potential) transmitter from Yokogawa's FLXA21 series. It is designed for continuous online measurement of pH and ORP in industrial process streams. The AA configuration indicates standard glass electrode input with built-in temperature compensation, and the UM suffix denotes USB modem communication capability for remote configuration and diagnostics. The transmitter outputs a 4–20 mA DC signal proportional to the measured value and supports HART 7 digital communication.

Yokogawa F3SP76-7S

Product Introduction: The F3SP76-7S is a safety-rated programmable logic controller (PLC) from Yokogawa's F3SP series, specifically engineered for Safety Instrumented Systems (SIS). It is certified to SIL 2 (Single Fault Tolerant) and SIL 3 (High Integrity) per IEC 61508 and IEC 61511 standards. The unit executes safety logic for emergency shutdown (ESD), fire and gas detection, and critical process interlocks in hazardous environments. The suffix -7S denotes the standard (non-redundant) CPU configuration with 7 slots of I/O capacity.

Yokogawa ANB10D-420/CU2T/NDEL

Product Introduction: The ANB10D-420/CU2T/NDEL is a 10-channel analog input module from Yokogawa's F3 I/O series, designed for use in CENTUM VP, CENTUM CS 3000, and ProSafe-RS safety systems. It accepts 4–20 mA DC current signals from field transmitters and digitizes them for transmission over the F Fieldbus (H1) or Modbus RTU communication network. The CU2T designation indicates a copper terminal block wiring configuration, and NDEL specifies the non-delay (fast scan) processing mode.

Yokogawa AXW4A

Product Introduction: The AXW4A is a dedicated analog telephone interface unit manufactured by Yokogawa Electric Corporation for integration with the CENTUM VP and CENTUM CS 3000 Distributed Control Systems (DCS). It serves as the communication gateway between the DCS operator stations and standard analog telephone sets, enabling voice communication for process operations, emergency announcements, and inter-station calling within a control room environment.

Yokogawa C3UL30066R

Working Principle: The C3UL30066R is a remote I/O module that connects to the C3000 series CPU via the Synchronous Serial Link (SSL) or EtherNet/IP network. It acquires digital/analog field signals, converts them to data packets, and transmits them to the CPU for logic processing. The CPU sends output commands back to the module, which drives field actuators (relays, solenoid valves, etc.). The module operates with deterministic scan timing synchronized to the CPU cycle.

Yokogawa UD1045B0KC-2XN

Working Principle: The UD1045B0KC-2XN acquires analog and digital input signals from field instruments, converts them via high-speed A/D converters (16-bit resolution), and displays/records the data on a color TFT LCD screen. Data is stored in internal flash memory (up to 8 GB) and can be exported via USB, Ethernet, or RS-232C. The recorder supports real-time trend display, bar graph, numerical display, and alarm monitoring.

Yokogawa PH450G-A-A/UM

Working Principle: The PH450G uses a glass electrode (for pH) or metal electrode (for ORP) combined with a reference electrode. The potential difference between the measuring electrode and reference electrode is proportional to the hydrogen ion activity (pH) or oxidation-reduction potential (ORP). The internal high-impedance amplifier converts the millivolt signal into a 4–20 mA DC output proportional to the measured value. Automatic Temperature Compensation (ATC) is performed using a built-in or external temperature sensor (Pt1000).

Yokogawa UR5AG3-500N-1S E-2SA-N

Working Principle: The UR5AG3 uses an electromechanical pen-drive system. Input signals (voltage, current, thermocouple, RTD) are converted by internal circuitry and drive a servo motor with pen arm across a moving chart paper. The pen deflects proportionally to the input signal, creating a continuous analog trace. The chart paper advances at selectable speeds (25mm/h to 600mm/h). Alarm contacts close when input exceeds preset thresholds.

Yokogawa S5WB13242

Model Breakdown:

  • S5 = CENTUM DCS System Family
  • WB = Module Type Designator (Interface/Communication Module)
  • 13242 = Specific Part Identification Number
Working Principle: The S5WB13242 module serves as a system bus interface or communication gateway within the CENTUM DCS architecture. It facilitates data exchange between the System Bus (SBUS) and field I/O modules, enabling real-time process data acquisition and control command distribution across the distributed control network.

Yokogawa F3LX01-0N

Product Type: Vortex Flowmeter Transmitter (No Local Display) Working Principle: Kármán Vortex Street Principle. A bluff body (shedder bar) is placed in the flow stream. As fluid passes the bluff body, alternating vortices are shed downstream. The frequency of vortex shedding is directly proportional to the flow velocity. The piezoelectric sensor detects the vortex-induced pressure oscillations and converts them into an electrical signal.

Yokogawa NFCP100-SS3

Product Introduction: The NFCP100-SS3 is a compact flow computer designed for custody transfer, energy measurement, and process flow totalization. It accepts inputs from flowmeters (pulse, 4-20 mA, frequency), temperature sensors (RTD, TC), and pressure transmitters to compute compensated mass/volumetric flow, totalized flow, and energy content. The "SS3" suffix denotes the specific input/output and communication configuration.

Yokogawa EJA430E-JBS4815

Product Series: EJA430E — DPharp Digital Pressure Transmitter Product Introduction: The EJA430E-JBS4815 is a high-performance absolute pressure transmitter using Yokogawa's DPharp (Digital Phase Measurement) single-crystal silicon resonant sensor technology. The "JBS" indicates a low-range absolute pressure model, and "4815" defines the specific output, process connection, and material configuration. It provides superior accuracy, stability, and fast response for absolute pressure measurement.
