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.
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.
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).
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.
Model Breakdown:
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.
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.
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.
Product Introduction: The MV20MV2010-3-4-1 is a Coriolis-type mass flowmeter that directly measures mass flow rate, fluid density, and temperature simultaneously. The model code breaks down as: MV20 = Coriolis series, MV2010 = 10 mm nominal bore, "3" = output/communication option, "4" = process connection option, "1" = special configuration. It uses the DPharp (Digital Phase Measurement) sensor technology for high accuracy and stability.
Product Introduction: The SDV551-P10 is a smart digital valve controller designed to operate pneumatic control valves (globe, butterfly, ball valves) with high precision. It accepts a 4-20 mA control signal from a DCS/PLC and converts it to a proportional pneumatic output signal to the valve actuator. The P10 suffix defines the specific input/output range and diagnostic configuration.
Product Series: UT450 Advanced Indicating Controller Product Introduction: The UT450-04/Z is a 1/4 DIN (96 × 96 mm) advanced panel-mount controller with 4 universal inputs, 3 relay outputs, 2 analog outputs, and Ethernet/RS-485/USB communication. The "04" denotes 4 control loops, and "Z" indicates the grounding terminal. It is designed for complex multi-variable process control in a compact footprint.
Product Series: UT35 Universal Indicating Controller Product Introduction: The UT35-A13501-A/RET1/RLEX/SPD/Z is a 1/8 DIN (96 × 48 mm) panel-mount universal controller with relay output, extended function, and specific configuration options. It accepts multiple input types and provides ON/OFF or PID control with relay and analog outputs. The suffix codes define: A13501 = input/output configuration, RET1 = relay output type, RLEX = extended relay function, SPD = serial communication option, Z = grounding terminal.
