Ratoc System Launches "LTE IoT Communication Unit" for All-in-One Remote Notification of Temperature Anomalies and Equipment Alarms

Ratoc System Co., Ltd. (Headquarters: Nishi-ku, Osaka; Representative Director and President: Masakazu Kondo; hereinafter "Ratoc System") will begin shipping its "LTE IoT Communication Unit," an all-in-one device capable of handling sensor connection to cloud transmission, starting July 2026.

This product features built-in LTE communication, enabling low-cost and simple remote monitoring while minimizing installation effort. It resolves issues where remote monitoring adoption is hindered by internal network limitations or high setup costs.

By simply inserting an optional thermistor temperature sensor into its dedicated port, users can initiate temperature monitoring using Ratoc System's "Hasarepo" system. The unit also supports equipment alarm notifications via voltage-free contact input. It is ideal for sites requiring remote monitoring of a single location, such as server rooms, small storage facilities, or specific equipment.

Furthermore, the unit supports RS-485 communication and 4-20mA input, with plans to expand its application to a wider range of equipment monitoring uses, including temperature controllers and liquid level monitoring.

All solutions come with a standard application, allowing immediate use of on-site verification, push notifications, and log management without the need for dashboard construction.

The company previously offered multi-point monitoring systems that consolidate multiple sensors via a gateway. With the addition of this LTE-integrated model, customers can now flexibly choose the optimal configuration for their site, ranging from simple monitoring of a single point to multi-point monitoring within a factory. Both types can be introduced and expanded from one to multiple locations according to needs.

Use cases for the all-in-one type:

- **Simple monitoring of "just one location" (All-in-one type)** This is suitable for cases where users want to easily remotely monitor the temperature or equipment alarms of a single location, such as server rooms, small power receiving equipment, or food storage facilities. By connecting a temperature sensor or voltage-free contact output from equipment to this product, the entire process, including cloud linkage, is completed by a single unit. Operations can commence without relying on internal networks. - **Managing "physically distant locations" (Distributed deployment of all-in-one type)** This is suitable for cases where users want to monitor distributed locations, such as equipment scattered across different floors within a building or within a large site. By installing this product at each location, each unit can operate independently without concern for communication distance or network configuration.

Key Features of "LTE IoT Communication Unit":

This product supports linkage with the "Hasarepo" temperature management/anomaly notification solution. By using Hasarepo, temperature and equipment alarms can be centrally managed on the cloud, including recording, visualization, and alert notifications. The LTE IoT Communication Unit enables the introduction of temperature monitoring and equipment anomaly monitoring with a minimal configuration.

- **All-in-one from sensor connection to cloud linkage** With built-in LTE communication, the unit handles everything from sensor connection to data transmission to the cloud in a single device. It can operate without connecting to an internal network, allowing remote monitoring to start immediately after installation. - **Remote monitoring and recording by simply inserting a temperature sensor** Installation is complete by simply inserting an optional thermistor sensor into its dedicated port. Temperature monitoring, recording, and anomaly notifications begin automatically. This reduces the burden of manual inspections and handwritten records, and prevents oversight by notifying users via smartphone, email, or alarm lamp when an anomaly occurs. - **Retrofit anomaly notification for existing equipment** Equipped with voltage-free contact input, it captures alarm signals from existing equipment and notifies via the cloud when an anomaly occurs. It also features voltage-free contact output, allowing anomaly notifications to be sent to alarm lamps or buzzers. This strengthens the monitoring system, including nights and holidays, without requiring equipment updates. - **External power drive suitable for continuous monitoring of permanent equipment** Operates with external power sources such as AC adapters, eliminating the need for battery replacement. Ideal for continuous monitoring of indoor equipment. - **Mountable on DIN rail** Compatible with 35mm DIN rails, suitable for installation in control panels and racks. It can be fixed by simply pulling up the top lever without tools, allowing seamless integration as an in-panel device.

Future Development: Solution Expansion tailored to Industrial Site Applications

In addition to temperature monitoring and equipment anomaly notifications, the LTE IoT Communication Unit will support various equipment monitoring solutions tailored to specific applications.

- **Support for remote monitoring system for temperature controllers** Scheduled to support RS-485 communication and voltage-free contacts. This will enable status monitoring and anomaly detection for equipment equipped with temperature controllers, such as saunas and hot springs. - **Support for remote monitoring system for liquid level/tank remaining volume** Through 4-20mA input (HART communication compatible), it will enable remote monitoring of tank remaining volume using level sensors.
