Product Details

MX110-VTD-L30 Product Description

The Yokogawa MX110-VTD-L30 is a 30-channel thermocouple and DC voltage input module engineered for the MX100 Distributed Data Acquisition System. Designed to serve as a critical node in industrial data link architectures, this module bridges field-level thermal and voltage signals directly into Ethernet-based plant networks, enabling real-time data acquisition, remote diagnostics, and seamless SCADA/HMI integration across smart factory environments. Whether deployed in energy monitoring, process temperature control, or multi-zone thermal mapping, the MX110-VTD-L30 delivers the signal fidelity and network connectivity that modern industrial automation demands.

In a connected factory data chain, the MX110-VTD-L30 operates as the front-end acquisition layer. Thermocouples and DC voltage transmitters wired to its 30 input channels feed live measurement data into the MX100 mainframe, which aggregates readings and transmits them upstream via Modbus TCP over standard Ethernet infrastructure. This architecture allows plant engineers to integrate temperature and process voltage data directly into Yokogawa STARDOM FCN/FCJ controllers, Yokogawa CENTUM VP DCS platforms, or third-party SCADA systems without additional protocol converters. The module's native Ethernet port connects to industrial managed switches — such as those in the Yokogawa ProSafe-RS safety network or compatible Layer 2/Layer 3 industrial Ethernet switches — ensuring deterministic data delivery across the plant LAN.

The data flow begins at the sensor level: Type K, J, T, E, R, S, B, N thermocouples and ±10 V / ±1 V DC voltage inputs are scanned at configurable intervals, with each channel independently calibrated for cold-junction compensation and linearization. Digitized values are time-stamped within the MX100 mainframe and transmitted to upstream systems including Yokogawa GA10 Data Logging Software, Yokogawa PRM Plant Resource Manager, or any Modbus TCP-compatible HMI panel. For facilities running Yokogawa Exaquantum plant historian or third-party OSIsoft PI System integrations, the MX110-VTD-L30's structured data output maps cleanly into historian tag databases, supporting long-term trend analysis and regulatory compliance reporting.

Remote diagnostics capability is a key operational advantage of the MX110-VTD-L30 within smart factory deployments. Channel-level alarm thresholds can be configured via the MX100 network interface, with alarm events transmitted in real time to SCADA dashboards or edge gateway platforms. When integrated with Yokogawa's OpreX Asset Management suite or compatible IIoT edge gateways, the module supports predictive maintenance workflows — flagging sensor drift, open-circuit faults, or out-of-range readings before they escalate into process shutdowns. This remote visibility eliminates the need for on-site inspection in hazardous or hard-to-access measurement zones, reducing maintenance costs and improving plant uptime.

System expansion is straightforward within the MX100 ecosystem. The MX110-VTD-L30 can be combined with complementary modules such as the MX110-UNV-M10 universal input module for mixed-signal acquisition, or the MX110-SDV-D08 digital I/O module for discrete status monitoring. Multiple MX100 units can be networked together via Ethernet, with a single Yokogawa GA10 or SCADA server polling all nodes through a unified Modbus TCP map. This scalable architecture supports phased factory expansion — adding measurement points without rewiring or replacing existing infrastructure. For facilities requiring wireless data backhaul, the MX100 network output can be routed through industrial cellular gateways or Wi-Fi access points compliant with IEEE 802.11 industrial standards, extending remote monitoring to geographically distributed sites.

Every MX110-VTD-L30 unit shipped by NANKMOS undergoes pre-delivery functional verification, including channel continuity checks, Ethernet link validation, and Modbus TCP communication testing. Units are supplied with original Yokogawa documentation, factory calibration certificates where applicable, and are backed by a 12-month warranty covering manufacturing defects and communication failures. Stock is maintained for prompt dispatch, supporting both urgent replacement orders and planned project procurement timelines.

In a typical smart factory deployment, the MX110-VTD-L30 sits at the data acquisition layer, collecting thermal and voltage signals from field instruments — including resistance temperature detectors wired through signal conditioners, thermocouple transmitters on process vessels, and DC voltage outputs from pressure transducers. These signals are digitized and passed to the MX100 mainframe, which acts as a local data concentrator before forwarding structured Modbus TCP frames to the plant network.

Upstream, a Yokogawa STARDOM FCN autonomous controller or a Yokogawa CENTUM VP field control station receives the Modbus data and integrates it into the process control loop. HMI panels — whether Yokogawa's own ProSafe or third-party Weintek/Siemens HMI terminals — display live channel readings and alarm states. For facilities using Yokogawa GA10 Data Logging Software, the MX100 network node is polled directly, with all 30 channels logged at configurable scan rates and exported to CSV or database formats for quality records and process audits.

At the edge layer, industrial Ethernet switches route MX100 data traffic alongside signals from Yokogawa YS1700 single-loop controllers, Yokogawa WT series power analyzers, and third-party Modbus RTU devices bridged through protocol gateways. IIoT edge computing platforms aggregate these data streams, applying local analytics before forwarding summarized datasets to cloud-based MES or ERP systems. This end-to-end architecture — from thermocouple to cloud — is the backbone of transparent, data-driven smart factory operations.

Many industrial facilities face persistent data gaps: legacy field instruments that speak only analog 4–20 mA, protocol mismatches between Modbus RTU field devices and Ethernet-based SCADA servers, and measurement islands where temperature data never reaches the control room in real time. The MX110-VTD-L30 addresses these challenges by providing a direct Ethernet-connected acquisition front-end that eliminates the need for intermediate RTU converters in thermocouple measurement applications.

For sites struggling with data silos, the MX100 system's ability to network multiple modules under a single IP address simplifies SCADA tag mapping and reduces configuration overhead. Alarm tracking is centralized — threshold violations on any of the 30 channels trigger Modbus exception responses that SCADA systems can poll and log without custom scripting. Remote diagnostics via the Ethernet interface allow maintenance engineers to verify channel health, review historical alarm logs, and adjust scan intervals from the control room or remotely via VPN, without dispatching technicians to the field panel.

Production line transparency improves significantly when thermal data from critical process points — furnace zones, heat exchangers, reactor vessels — is continuously streamed to the plant historian. Trend visualization in Yokogawa Exaquantum or compatible SCADA platforms enables engineers to correlate temperature excursions with product quality deviations, supporting root-cause analysis and continuous improvement initiatives. System expansion requires only adding MX100 modules to the existing Ethernet network, with no changes to the SCADA communication architecture.

Q1: What communication protocol does the MX110-VTD-L30 use, and is it compatible with third-party SCADA systems?The MX110-VTD-L30 communicates via Modbus TCP over standard 10/100BASE-TX Ethernet. This is one of the most widely supported industrial protocols, making the module compatible with virtually all major SCADA platforms including Wonderware, Ignition, iFIX, and Yokogawa's own CENTUM VP and GA10 systems. No proprietary drivers or middleware are required for basic integration.

Q2: How does the module support remote diagnostics and predictive maintenance?Channel-level alarm thresholds are configurable via the MX100 network interface. When a thermocouple open-circuit, over-range, or under-range condition is detected, the module flags the channel status in its Modbus register map, which SCADA or HMI systems can poll and display as real-time alarms. Combined with IIoT edge gateways, these alarm events can trigger automated notifications to maintenance teams, supporting condition-based maintenance workflows without on-site inspection.

Q3: Can the MX110-VTD-L30 be expanded as measurement requirements grow?Yes. The MX100 system supports multiple module types — including the MX110-UNV-M10 universal input module and MX110-SDV-D08 digital I/O module — that can be added to the same mainframe or networked as additional Ethernet nodes. The Modbus TCP register map scales accordingly, and SCADA systems simply add new tags to accommodate the expanded channel count. This modular architecture protects the initial investment while supporting phased factory expansion.

Q4: What pre-shipment testing and warranty coverage does NANKMOS provide?Every MX110-VTD-L30 unit undergoes pre-delivery functional verification including channel continuity checks, Ethernet link validation, and Modbus TCP communication testing. All units are supplied with original Yokogawa documentation and are backed by a 12-month warranty covering manufacturing defects and communication failures. NANKMOS maintains ready stock for prompt dispatch to support both urgent replacement and planned project procurement.
