Converter ET-485 NTET4850A

Ethernet/Modbus RTU communication converter – a bridge between automation worlds

The ET-485 device is a microprocessor-based converter that enables integration of Ethernet 10BASE-T and 100BASE-T networks with devices using the RS-485 interface and the Modbus protocol. This is a key solution for industrial automation systems where communication between modern Ethernet networks and older Modbus devices is necessary. It acts as a Modbus server, forwarding requests from Ethernet clients to devices on the Modbus network and back.

The ET-485 converter is not just a simple data relay. It offers advanced configuration features, such as flexible addressing in the Ethernet network (static or dynamic IP address, the ability to change the MAC address) and access security (password for configuration, IP address filter). This allows for secure and efficient communication management in the network. It supports various data exchange modes in Modbus RTU or ASCII network, with the ability to configure parity control and transmission speed.

Versatility and functionality for professionals

ET-485 stands out with its extensive monitoring and control capabilities. It allows reading parameters of connected devices, sending programmable SMS and email notifications, and creating a history of parameters in the form of graphs. This gives the user a complete picture of the system situation and allows for quick response to any problems. Remote control of devices and access via the Internet via Ethernet open up new possibilities for remote management and diagnostics. The device allows connecting up to 247 Modbus devices simultaneously, making it an ideal solution for complex automation systems.

The converter is mounted on a DIN rail and is characterized by compact dimensions (95x52x67mm). It has LED indicators informing about the connection status and a web interface for configuration and monitoring. The power supply is 230/240 AC. The use of high-quality components ensures reliable operation in a wide temperature range (from -35°C to +55°C). It meets the requirements for electrical safety (class II, protection degree IP20/IP30).
