Product Details

MW100-E-1H Product Description

The Yokogawa MW100-E-1H is a high-performance Ethernet communication module engineered for the MW100 Data Acquisition Unit series, purpose-built to serve as the data backbone of energy-aware industrial automation environments. In modern manufacturing facilities where energy cost reduction, load balancing, and production line efficiency are strategic priorities, the MW100-E-1H delivers the real-time connectivity and data throughput required to make intelligent energy decisions at every level of the control hierarchy.

Designed for seamless integration into energy management systems (EMS) and SCADA platforms, the MW100-E-1H enables continuous acquisition of power consumption data, thermal load metrics, and equipment utilization rates across distributed production assets. Whether deployed in automotive assembly, chemical processing, food and beverage manufacturing, or semiconductor fabrication, this module provides the communication infrastructure that transforms raw sensor data into actionable energy intelligence.

The MW100-E-1H is not a standalone device — it is the communication nerve center of a coordinated, energy-optimized automation architecture. In a typical smart production line deployment, the module interfaces directly with the Yokogawa MW100 main unit and its associated input modules, aggregating analog signals from current transformers, voltage transducers, and power quality sensors. This data is then transmitted over Ethernet to upstream control and monitoring systems in real time.

When integrated with a Yokogawa STARDOM FCN/FCJ autonomous controller or a third-party PLC such as a Siemens S7-1500 or Mitsubishi MELSEC iQ-R series, the MW100-E-1H enables closed-loop energy control strategies. The PLC can receive power consumption feedback from the MW100 system and dynamically adjust the setpoints of connected Yaskawa GA700 variable frequency drives (VFDs) or Mitsubishi FR-F800 inverters, reducing motor speed during low-demand periods and cutting unnecessary energy draw without compromising throughput.

For servo-driven axes on precision assembly lines, the MW100-E-1H works alongside Yokogawa WT series power analyzers to capture regenerative braking energy data from Panasonic MINAS A6 servo drives, enabling engineers to quantify energy recovery rates and optimize deceleration profiles. This data feeds into the plant's energy management system via Modbus TCP, where it is correlated with production output metrics to calculate energy intensity per unit produced.

The module also communicates with Yokogawa EJX series differential pressure transmitters and flow sensors deployed on compressed air and cooling water circuits — two of the largest sources of hidden energy waste in industrial facilities. By monitoring these utility flows in real time alongside electrical load data, the MW100-E-1H gives energy managers a complete picture of total energy consumption, enabling targeted reduction initiatives.

On the HMI and visualization layer, the MW100-E-1H supports direct data feeds to Yokogawa FAST/TOOLS SCADA and third-party HMI platforms via standard OPC-DA or Modbus TCP interfaces. Operators can monitor live energy dashboards, set demand threshold alarms, and trigger automated load-shedding sequences when peak demand limits are approached — all without manual intervention.

Industrial production lines face a fundamental challenge: energy is consumed continuously, but value is only created during active production cycles. Idle equipment, inefficient motor loading, thermal runaway in drive cabinets, and undetected power quality issues all contribute to energy waste that directly erodes profitability. The Yokogawa MW100-E-1H addresses this challenge by providing the high-resolution, time-stamped energy data that modern production optimization requires.

By deploying the MW100-E-1H at key energy measurement points — motor control centers, compressed air stations, HVAC systems, and process heating zones — plant engineers can establish accurate energy baselines for each production segment. These baselines become the foundation for ISO 50001 energy management programs, enabling systematic identification of energy-saving opportunities and verification of improvement measures.

The module's high-speed data acquisition capability allows it to capture transient load events — motor start surges, welding pulses, press impacts — that would be invisible to conventional energy meters with 15-minute demand intervals. This granular data enables engineers to redesign production schedules to stagger high-demand events, reducing peak demand charges that can account for 30–40% of industrial electricity bills.

For predictive maintenance applications, the MW100-E-1H provides the continuous electrical signature data needed to detect early signs of motor degradation, bearing wear, and insulation breakdown. Abnormal increases in motor current draw, power factor deterioration, or harmonic distortion levels can be flagged automatically, allowing maintenance teams to schedule interventions during planned downtime rather than responding to unexpected failures that disrupt production rhythm and waste energy through emergency restarts.

The result is a production line that runs at its designed energy efficiency point — motors loaded optimally, drives operating in their high-efficiency zones, utilities consumed only when needed, and maintenance performed proactively. The MW100-E-1H is the measurement and communication foundation that makes this level of energy discipline achievable in real industrial environments.

All units are pre-tested prior to shipment, covered by a 12-Month Warranty, and available from stock for immediate delivery to support urgent project timelines.

Q1: What energy saving results can I expect from deploying the MW100-E-1H in my facility? The MW100-E-1H itself is a measurement and communication module — its energy saving value comes from the visibility it provides. Facilities that implement real-time energy monitoring with the MW100 system typically identify 10–25% energy reduction opportunities through load scheduling optimization, VFD setpoint adjustment, and elimination of idle-state consumption. Actual savings depend on your baseline energy profile and the control actions taken based on the data.

Q2: Is the MW100-E-1H compatible with my existing SCADA or EMS platform? Yes. The MW100-E-1H supports Modbus TCP, FTP, HTTP, and SMTP protocols, making it compatible with the majority of industrial SCADA, DCS, and energy management systems on the market. It can also be integrated with IIoT platforms via standard Ethernet connectivity. For specific compatibility verification with your system, please contact our technical team with your platform details.

Q3: Can the MW100-E-1H replace an older MW100 Ethernet module, and what is the replacement process? The MW100-E-1H is designed as a direct replacement for earlier MW100 series Ethernet communication modules. The replacement process involves powering down the MW100 unit, swapping the module, restoring network configuration parameters, and verifying communication with the host system. No changes to the MW100 main unit or input modules are required. Our team can provide configuration guidance to ensure a smooth transition with minimal downtime.

Q4: What does the 12-Month Warranty cover, and how is the testing process conducted before shipment? Every MW100-E-1H unit undergoes functional testing prior to shipment, including Ethernet communication verification, protocol response testing, and visual inspection for physical integrity. The 12-Month Warranty covers manufacturing defects and functional failures under normal operating conditions from the date of delivery. Units are shipped with appropriate ESD protection packaging to prevent transit damage. For warranty claims or technical support, contact our team directly.
