TLD-2 is a high-precision insulation monitoring device that enables the monitoring of leakage current in low-voltage circuits without stopping the power supply to the equipment. It supports single-phase and three-phase systems and allows simultaneous visibility of up to two circuits. It also comes standard with connection to upper systems via RS-485 (Modbus RTU) and alarm notification functions through contact output. With reliable data and operability, it supports safety and efficiency in the field. *Related links (Takeuchi Electric website) provide various downloadable materials.

At the chemical manufacturer, when trying to operate the outdoor blower motors, the leakage circuit breaker would trip, preventing operation. While predictive maintenance is necessary, there were challenges such as the effort required due to the presence of multiple blowers. Therefore, we introduced our "IRS-9500 (main unit)." Once a week, we create a timing for all blowers to stop and conduct a collective measurement. If any measurements fall below the pre-set threshold, an abnormal output is sent to the PLC, and a notification is sent to the office. Additionally, using the setup tool (software included with the main unit), it is possible to check the historical data of each blower and understand degradation trends. We received feedback from customers stating that "it is much easier to manage than manual methods and is very convenient." *For more details, please refer to the PDF document or feel free to contact us.

As an issue, it was pointed out that "due to heavy rain, the river swelled, and the pump that was supposed to drain water did not operate due to insulation degradation," and "after that, workers were regularly conducting insulation measurements, but since the pump room was located far away, it was very difficult and labor-intensive, so we wanted to implement some measures." Therefore, we introduced our "IRS-500 (main unit)" and "IRS-DA (analog output device)." The measured values are input from the "IRS-DA" to the control panel's PLC. With the PLC system, if the measured value falls below the preset insulation degradation threshold, a notification is sent to the office as an insulation degradation alarm. We received feedback from our customers saying, "It automatically measures, and we can check the degradation alarm without having to go on-site, which has made things much easier." *For more details, please refer to the PDF document or feel free to contact us.

• Wastewater/wastewater treatment equipment

At an automobile manufacturer, a rare short circuit occurred due to insulation degradation while using a machining tool for overhauls, nearly resulting in a fire. It was necessary to take urgent measures to prevent recurrence. Therefore, we introduced our "IRS-500 (main unit)" and "GP4115T2D-IRS (display unit)." To detect signs of degradation at an earlier stage, we utilized the pre-warning function of the display unit, setting it to issue an alert if the values fell below a predetermined threshold. During equipment downtime, insulation resistance is automatically measured, and the values are checked on the display unit before operation. We received feedback from the customer stating, "Over the years since the introduction, there have been several alarms for insulation degradation, but we were able to take measures before any failures, which was extremely helpful." *For more details, please refer to the PDF document or feel free to contact us.

The "Insulation Resistance Monitoring Device" is a product that contributes to reducing maintenance costs and preventing unexpected equipment failures and accidents by automating the monitoring of insulation resistance in electric motors and other equipment. Our popular product line "IRS Series" now includes the "Insulation Resistance Monitoring Device IRS-9000 Series." 【New Features】 - Capable of monitoring up to 9 devices with a single unit - Compatible with large electric motors (the maximum monitored equipment voltage is 440V) - Supports Modbus RTU, allowing data communication with PLCs and inverters - Easy configuration of judgment conditions and settings using a setup tool software Our product "Insulation Resistance Monitoring Device (IRS)" received the "Invention Award Nikkan Kogyo Shimbun Award" at the 46th Invention Awards co-hosted by the Japan Invention Promotion Association and Nikkan Kogyo Shimbun. We also offer single-device monitoring types, "IRS-250 / IRS-500." https://www.ipros.jp/product/detail/2000259557

• Insulation Tester

It measures highly reliable insulation resistance using the Megger method. It automatically monitors the insulation condition of various motors mounted on machine tools. This reduces maintenance costs and the burden of maintenance inventory costs, allowing for the prevention of sudden line stoppages in advance. No power outage of equipment is required. Due to the Megger method, it can measure high-precision values at a lower cost than the I0r method. Measurements can be taken after the motor has completely stopped, thanks to a delay timer. Alarm output settings can be differentiated from four types of measurement values (selectable from 1MΩ, 5MΩ, 10MΩ, 20MΩ). It is highly versatile and does not depend on the equipment, capacity, or manufacturer. Although it is a high-voltage measurement method, there is no concern about electric shock. It can also accommodate equipment that requires safety circuits. By connecting an optional touch panel, detailed settings and history management can be performed.

We are introducing a video that outlines the flow from wiring to data collection for the "Processing Abnormality Detection Device CIU." It concisely summarizes the necessary signals, data collection methods, and data verification processes. This content is useful not only for those considering implementation but also for those who have already purchased the device. We encourage you to watch it. By implementing the CIU in machine tools such as machining centers, the conditions during processing loads can be visualized as waveforms, allowing for the detection of tool wear and damage, and enabling the determination of the appropriate timing for tool replacement. *For more details about the product, improvement cases, and mechanisms, please view the PDF available for download or feel free to contact us. *Demo units are available for loan!
