A Predictive Maintenance Solution to Prevent Sudden and Critical Failures
Realizing Unstoppable Manufacturing Equipment
With manufacturing sites experiencing labor shortages and aging equipment, there is a growing need for “predictive maintenance.” Predictive maintenance, whereby data is collected from various sensors to predict equipment performance degradation or failure and perform maintenance at the optimal time, is an essential technology for safe and stable operations.
The Multi-Sensing Remote I/O Analog Sensing Unit VZ20X performs reliable sensing to visualize the status of legacy equipment that has not been converted to digital operation. By incorporating IoT and AI, the unit identifies signs of deterioration and facilitates predictive maintenance. As such, it keeps problems with equipment to a minimum and helps ensure improved productivity and efficiency in facility maintenance.
The VZ20X Meets the Needs of the Following Users:
- Those who want to inspect and replace industrial machinery (production equipment) in a timely manner.
- Those who want to add to or improve existing industrial machinery without placing a strain on it.
- Those who want to prevent minor stoppages and major failures in industrial machinery.

The Predictive Maintenance That Manufacturing Sites Require
In conventional manufacturing, maintenance consists of “corrective maintenance,” performed after a failure, and “preventative maintenance,” performed periodically. However, these maintenance methods present problems such as labor-intensive maintenance work and the inability to prevent sudden equipment failures. As such, they represent a major burden for manufacturing sites, which are increasingly short on manpower.
This is why “predictive maintenance,” whereby signs of failure are detected and maintenance is performed accordingly, has been attracting attention. With predictive maintenance, maintenance is performed only on equipment that shows signs of failure, thus significantly reducing the man-hours and cost involved in maintenance operations. In addition, downtime due to sudden equipment failures can be minimized, thus improving uptime.
The VZ20X, Enabling Predictive Maintenance
The VZ20X is the world’s smallest class of sensing remote I/O unit, capable of simultaneously measuring various analog sensor signals with high speed, high accuracy, and at high voltages. The measured data is sent via Ethernet to a higher-level system that performs monitoring and constantly assesses the status of the facility. Predictive maintenance is achieved by quickly detecting signs of equipment failure or deterioration, thereby resolving issues of reduced uptime and safety due to equipment stoppages.

Benefits of VZ20X Installation
The VZ20X is equipped with the ideal features for implementing predictive maintenance. This section describes some of the benefits of installing the VZ20X at your manufacturing site.
Converting Signs of Deterioration Into Digital Data Allows Optimal Timing of Replacement and Inspection
The VZ20X collects data from multiple sensors simultaneously at high speed and with high accuracy to visualize signs of equipment deterioration. Combined with Yokogawa Electric’s proprietary AI, equipment anomalies and signs thereof can be analyzed and detected at an early stage. This makes possible CBM (condition-based maintenance), in which maintenance is performed at the optimal timing in accordance with the condition of the equipment. This reduces the man-hours required for inspection and parts replacement, helping to achieve labor savings in maintenance work.
Easy Installation on Existing Equipment to Acquire Diagnostic Data and Make Improvements
The VZ20X is one of the world’s smallest analog sensing units, shorter and narrower than a business card, and weighing less than 200g. Because it can fit in the gaps between production equipment, it can be easily replaced, minimizing the need for extensions or modifications to existing facilities. It can be applied to evaluating the performance of batteries installed in tight spaces inside a vehicle, or to predictive maintenance of unmanned vehicles.
Furthermore, it employs a push-in connection mechanism that allows installation simply by inserting a ferrule terminal, eliminating the need for special tools. These advantages make it easy to install on any piece of equipment without requiring much space or wiring, allowing predictive maintenance and evaluation of products and components.
High Noise Resistance Helps Ensure Safe Operation
The VZ20X provides stable data measurement thanks to its improved isolation between input channels and noise resistance. Because it can measure highly reliable data even when simultaneously measuring multiple channels or in environments where noise is likely to occur, it is able to accurately analyze the cause of equipment failures. This reduces the number of cases of imprecise maintenance, which in turn reduces the man-hours required for maintenance work.
Also, when using VZ20X in production quality evaluation, safe and reliable testing can be performed because it is less susceptible to the characteristics of products and components and the testing environment.
High-Speed and Highly Accurate Sensing Detects Signs of Failures Before They Occur
A single VZ20X unit can measure 8 channels of analog inputs at high speed with a sampling cycle of 1 ms. It supports simultaneous measurement by up to 15 units across 120 channels, helping to enable predictive maintenance at manufacturing sites where large amounts of equipment and many sensors are in operation. It is also capable of extremely precise measurement with synchronization accuracy of ±100 µs, measurement accuracy of ±0.05%, temperature measurements accurate to within ±0.16°C, and voltage measurements accurate to ±1mV. In this way, high-speed and highly accurate measurements that do not miss even the slightest changes in the equipment enable the prediction of failures.
Monitors Equipment Status With Support for All Kinds of Analog Sensors
DC voltage, 4-wire resistor, thermocouple (TC), and 3-wire/4-wire RTD can be measured with a single unit. The use of analog sensors that support these inputs allow a variety of data to be measured, eliminating the need to use numerous data measurement devices for different kinds of sensors.
Accurate Sensing Even Without a Power Outlet
Using the USB Type Detection Disable feature, the VZ20X can be powered by sources other than USB Type-C. Powering the device from a PC’s USB Type-A port eliminates the need for an external 24V DC power supply or power cable, reducing installation and wiring costs. Moreover, by connecting the VZ20X to a commercially available PoE (Power over Ethernet) splitter, it is possible to supply power using an Ethernet cable.
Examples of VZ20X Applications
VZ20X can be used in CBM (condition-based maintenance) at manufacturing and logistics sites.
Manufacturing Plants: Predictive Maintenance of Manufacturing and Logistics Equipment
Recently, manufacturing plants have been making use of automatic guided vehicles and other advanced automation systems to reduce the number of workers on production lines. However, there are still many pieces of analog equipment for which it is difficult to successfully detect signs of deterioration, leading to issues of reduced operating rates due to sudden failures.
The VZ20X is extremely small and lightweight, about the size of a business card, and can be retrofitted to existing analog equipment. Furthermore, when combined with Yokogawa Electric’s data logging software (GA10), real-time OS controller (e-RT3 Plus), and its proprietary AI, highly accurate data collection, monitoring, anomaly detection, and causal analysis can be achieved. Properly timed maintenance reduces the number of man-hours required to troubleshoot problems associated with equipment stoppages, contributing to improved uptime and labor savings.
