Interface controller EM-481 NTEM48100

Smart interface for monitoring and remote control

The EM-481 interface controller is an advanced device that enables data collection from devices using the MODBUS protocol, transferring it to a server, and remote access to this information. It is an ideal solution for both professionals involved in industrial automation and end-users who need real-time monitoring and control. The device combines data collection, alarming, and simple control functions, offering flexibility and reliability in various applications.

Flexibility of connections and data security

EM-481 offers a wide range of communication possibilities – wired (Ethernet) and wireless (GSM/LTE). It automatically selects the optimal connection method to the server and also allows manual configuration of GSM network parameters. Additionally, it provides a high level of security thanks to access protection, such as passwords for configuration and MODBUS connections, the ability to restrict access to trusted servers only, and connection authorization. These are key aspects to ensure data integrity and protection against unauthorized access.

Functionality tailored to needs

The device supports various data exchange modes via RS-485 (RTU or ASCII), offering a wide range of transmission speeds and parity control. The ability to program data collection, define events and actions based on these events allows you to create a personalized monitoring and control system. Additional service functions, such as a real-time clock and the ability to update software, increase ease of use and ensure long-term reliability. EM-481 can handle up to 247 Modbus devices simultaneously.
