The NTROB NT-MB1200 is a high-performance Modbus-TCP bus coupler designed for modular slice I/O systems. Operating over standard Industrial Ethernet with CAT6A STP cabling, it seamlessly bridges Modbus-TCP client networks (such as SCADA systems, PLCs, and Industrial Edge Controllers) with flexible field I/O expansion modules. Supporting up to 32 expansion sub-modules (Digital, Analog, and Function modules) with built-in disconnection diagnostics and a high 10A I/O output current capacity, the NT-MB1200 offers reliable, cost-effective distributed control for modern industrial automation.
