Modbus Gateways - Modbus RTU/TCP/ASCII converters

This category includes Modbus gateways communicating in Modbus RTU/ASCII standard with RS-232 or RS-485 interface and Modbus TCP with Ethernet interface. Modbus is used in industrial automation, among others for communication with control systems, air conditioning, heating, BMS and many others. Due to its versatility, the Modbus protocol is one of the most popular communication protocols in the industry.

Get to know our Modbus Gateways products

We have prepared various industrial Modbus gateways for you, depending on the type of installation, the operating temperature range and the number of RS-232 and RS-485 ports on the Modbus RTU/ASCII side. Each converter available in our offer is easy to mount on DIN rail (standard or with mounting brackets), immunity to electromagnetic interference and the possibility of installation in outdoor boxes and environments with a wide operating temperature range from -40°C to 85°C. Our Modbus gateways are versatile enough to work in a variety of industrial environments, with the free software included with each device that is easy to configure.

Our offer also includes Modbus TCP to ASCII gateways, Modbus RTU to ASCII gateways and Modbus RTU to Modbus RTU gateways (multimaster-mulsitslave or slave-slave).

For your convenience, we divided our Modbus gates according to the price ranges in which they are located. Select the product you are interested in and get familiar with the technical specification:
