The in-house pager system and pocket calling terminal 'PCall-1' is a calling system that instantly notifies the terminal from a calling switch or abnormal output signals from an automatic calling unit. It operates in the 920MHz band and can be used without interfering with Wi-Fi. Expanding the communication range through wireless relay stations is also easily achievable. It supports customization to meet the needs of different sites and can perform calls using a light sensor to activate the display light. 【Features】 ■ Capable of sending messages to multiple terminals from a calling switch ■ Automatic calling based on abnormal outputs from equipment ■ Easy integration with multiple devices and equipment ■ Can also be linked with a forklift calling system * We are currently offering product introduction materials with usage examples. Please check them out via "PDF Download."

The "UMM-2400" is a built-in antenna type 2.4GHz wireless modem with high flexibility in installation location. By integrating the radio and antenna, it is made drip-proof, and the communication cable and power supply are combined into one, making 2.4GHz communication easier to use. 【Features】 ■ High flexibility in installation location with built-in antenna ■ Integration of radio and antenna ■ Drip-proof design, with communication cable and power supply combined ■ Easier to use 2.4GHz communication *For more details, please feel free to contact us.

The "Network Master" is a parent wireless device that can be connected to either "ETHERNET" or "RS-232C." It can be used as a wireless information collection network system. Especially in large-scale systems, by connecting the same Network Master as a relay device via LAN, data from numerous child devices installed in a wide area can be collected in a short time. 【Features】 ■ Can be connected to either "ETHERNET" or "RS-232C" ■ Used as a wireless information collection network system ■ In large-scale systems, data from numerous child devices installed in a wide area can be collected in a short time *For more details, please feel free to contact us.

The "FCall-M/FCall-A" is a terminal for calling forklifts using switches or sensors. It is possible to notify the forklift whether the operator presses the switch or the sensor detects it. The switch part is illuminated, allowing you to determine the status of the call communication based on the blinking or lighting condition. 【Features】 ■ Wireless ■ Call forklifts using switches or sensors ■ Illuminated switch part ■ Determine communication status based on blinking or lighting condition *For more details, please feel free to contact us.

The monitoring system "vibInsight" from Arrow Seven conducts regular measurements of bearing [vibration and temperature anomalies], which account for about half of the causes of machine failures, using high-sensitivity sensors via battery-operated wireless devices. It detects signs of bearing anomalies quantitatively, without relying on human experience or intuition, thereby reducing downtime caused by bearing failures. Not only does it reduce manufacturing losses, but it also eliminates the need for personnel to check for anomalies, contributing to labor savings. One master unit can manage up to 100 sensors, with a wireless transmission range of 1.2 km in line of sight and over 100 meters within a factory. *With the placement of wireless relay stations, measurements can be extended over a wider area. **Features** - The vibration sensor responds up to a high frequency of 20 kHz. - Minimal effort and low cost for power and communication wiring. - The battery-operated measurement device has a battery life of about 10 years with measurements taken once a day. - Up to 10 relay devices can be connected. - The wireless frequency band is 920 MHz, with no interference from WiFi and other devices. - Raw waveform data during measurements is also collected, allowing for comparisons with past data. - FFT analysis display is possible from raw waveform data. *For more details, please refer to the catalog. Feel free to contact us with any inquiries.

"vibInsight" is a system that detects abnormal signs in motor bearings and similar components. It monitors temperature and humidity wirelessly. Data collection is conducted using our proprietary wireless relay network system, allowing for extensive measurements and data transmission. Furthermore, it can be easily installed with wireless relays, offers flexible placement, and operates on batteries for 10 years. 【Features】 ■ Two sensors can be connected to one terminal ■ Temperature and humidity sensor terminals can also collect data on the same wireless network ■ Compatibility with various sensors such as current sensors is also possible ■ 10 years of operation on batteries (when measuring once a day) ■ A flexible wireless relay network that can cover a wide area freely *For more details, please refer to the PDF document or feel free to contact us.

"vibInsight" is a vibration and temperature predictive monitoring system that utilizes a wireless relay transmission system to enable data collection from a wide range. The cause of equipment and rotating machinery failures is nearly half due to bearing failures. By regularly measuring peak values and checking trends, it is possible to detect anomalies. Furthermore, with a response frequency of 20kHz, it captures signals from low to high speeds without loss and converts them into electrical signals. 【Features】 ■ Data collection from multiple buildings and multiple floors is possible with MAX10 relay stages. ■ Data can be collected beyond just bearing vibrations: - Ambient temperature - Current ■ New sensor designs can also be added. *For more details, please refer to the PDF materials or feel free to contact us.

"PCall-1" is an in-house pager system that ensures reliable calling through sound, vibration, and messages. It is a portable pocket-type device equipped with a strap attachment. With its response function, you can feel secure on-site, and the calling messages can be easily configured using a management PC. 【Features】 ■ Reduces running costs compared to providing mobile phones ■ Comes with a strap attachment ■ Reliable calling through sound, vibration, and messages ■ Immediate peace of mind on-site with the response function ■ Calling messages can be easily configured using a management PC ■ Covers a wide area with 920MHz band wireless *For more details, please refer to the PDF document or feel free to contact us.

UMR-920B uses 920MHz band wireless to enable wireless communication with RS-485 Modbus RTU. - 1-to-1 communication - 1-to-N communication - Cases where the slave side is prioritized with multiple RS-485 connections Various configurations are possible, and it can also accommodate mixed cases of the above scenarios.
