Yokogawa Electric Corporation announced that it has developed the OpreX Multi-Sensing Remote I/O as an addition to its OpreX Components lineup. OpreX Multi-Sensing Remote I/O devices accurately obtain data from multiple sensors, convert it to a digital format, and transfer it to a higher-level system for monitoring.

The first model is the VZ20X Analog Sensing Unit, which is being released for sale on August 31 in 64 countries and regions in the Asia-Pacific and the Middle East. The smallest-in-class VZ20X is a high-speed, high-precision, and highly noise-resistant device that is capable of simultaneously collecting data from analog sensors on up to 120 channels. With a height and width less than that of a typical business card and weighing less than 200g, it is suitable for installation wherever space is at a premium, including on production equipment.

Leveraging such characteristics and the capabilities of Yokogawa's AI technology, users of the VZ20X will be able, for example, to detect when an abnormality is likely to occur on a production line, so that condition-based maintenance (CBM) can be performed at a suitable time. The VZ20X is also able to accurately collect data needed for the development of components, such as the on-board batteries used in electric vehicles (EVs), plug-in hybrid vehicles (PHVs), and fuel cell vehicles (FCVs).

Features of the new VZ20X remote I/O includes as follows;

World-class compact design

Shorter and narrower than a business card and weighing less than 200g, the VZ20X is suitable for installation in tight spaces. As well as minimizing the need for the reconfiguration of existing production equipment, it is ideally sized to be mounted on unmanned transport vehicles and other vehicle types for the running of battery performance assessments, performance of preventive maintenance, etc.

Easy connection of devices using push-in connections and ferrule terminals.

Power can also be supplied via USB (Type C).

 

High-speed, high-precision, multi-channel synchronization, and high noise resistance

High-speed: Analog input signals can be sampled at 1 millisecond (0.001 seconds) intervals.

High precision: Synchronization accuracy of ±100 microseconds (1 microsecond = 1 millionth of a second), measurement accuracy of ±0.05%, temperature measurements accurate to within ±0.16℃ or less, and voltage measurements accurate to ±1mV

Multi-channel synchronization: With each module having 8 channels, a maximum of 15 units can be connected, enabling simultaneous measurement across up to 120 channels.

High noise resistance: Input channels are insulated from each other, so data can be accurately measured even in a noisy environment.

Support for a range of analog sensors

A single module can accept a wide range of analog inputs including DC voltage signals, unified signals, resistance signals, and temperature signals from sensors, such as thermocouples (TC) and 3-wire/4-wire resistance temperature detectors (RTD). By accommodating inputs from a variety of analog sensors, it facilitates the monitoring and control of a wide range of variables, including voltage, temperature, humidity, pressure, and vibration.

Major target markets include transport and logistics, automobiles and machinery, electronic devices, energy and materials, food, and agriculture.
