Protocol converter EM-482-1 NTEM48201

Protocol Converter Modbus – connectivity in TCP/IP and RS-485 networks

This EM-482-1 converter is a solution for integrating devices using the Modbus protocol in Ethernet networks with access via Wi-Fi and systems based on the RS-485 interface. It enables effective communication between various automation and monitoring elements, regardless of their physical location. It is an ideal solution for both installers of building automation systems and end-users who need remote access to Modbus device data.

Flexibility and reliable connection

EM-482-1 was designed with demanding operating conditions in mind. Equipped with an external antenna, it provides a stable Wi-Fi connection even in places with a weak signal – for example, in metal control cabinets. The converter offers a wide range of configurable RS-485 settings, allowing it to be adapted to different devices and network topologies. The ability to choose master or slave mode, transmission speed, parity, number of stop bits, and transmission delay ensures compatibility with most Modbus RTU devices on the market.

Monitoring and remote control functions

The converter is not limited to just transmitting data. It offers advanced monitoring and remote control functions that increase the efficiency and safety of automation systems. The most important of these include:

• Parameter reading: Access to data from connected Modbus devices in real time.
• Notifications: Programmable SMS and email notifications when specified parameter values are exceeded.
• Data history: Saving data in the form of graphs, allowing analysis of trends and diagnosis of problems.
• Remote control: The ability to remotely control connected devices via Wi-Fi or the Internet.
• Security: Access protection with passwords for device configuration, Modbus network connection, and data reading/writing.
• Updates: The ability to update the converter's firmware, allowing for the addition of new features and security improvements.

The converter supports simultaneous connection with up to 247 Modbus devices, making it an ideal solution for complex industrial and building automation systems. Configurable query redirection further increases the device's flexibility, allowing for optimization of communication in the network.
