Nishanth Technologies delivers reliable Modbus gateways enabling secure, redundant communication between Modbus TCP and Modbus RTU/ASCII, ensuring high-speed data exchange and stable connectivity for industrial.
The MGate MB3660 Series is a high-performance industrial Modbus gateway designed for reliable integration between Modbus TCP and Modbus RTU/ASCII networks. Built for demanding automation and utility environments, it ensures stable, secure, and uninterrupted communication across large-scale SCADA and control systems.
The MGate MB3660 Series (MB3660-8 and MB3660-16) is a powerful, industrial-grade Modbus RTU to Modbus TCP gateway engineered for large-scale Modbus deployments. Built with dual Ethernet ports, wide power input support, SD card backup, and isolation models, it ensures uninterrupted communication in mission-critical environments.
With support for up to 256 TCP master/client devices and 128 TCP slave/server devices, the MGate MB3660 simplifies Modbus network expansion by offering flexible routing, high-performance polling, and support for both RTU and ASCII protocols. Featuring built-in redundancy, intelligent command learning, and advanced auto-device routing, it is ideal for substations, SCADA systems, and industrial automation.
The MGate MB3660 Series is built to ensure uninterrupted industrial communication through redundant Ethernet design, high-polling efficiency, wide power support, and fault relay capabilities. Its 2 kV isolation (on “-I” models) makes it suitable for noisy industrial and power substation environments.
The MGate MB3660 supports both Modbus TCP and Modbus RTU/ASCII, offering unmatched flexibility:
8-port model: Supports up to 248 serial slave nodes
16-port model: Supports up to 496 serial slave nodes
Each serial port can be configured individually for baudrate, serial mode, and protocol—allowing mixed environment integration through a single gateway.
