Introduction

The SC10MK2-485 MT is a high-performance, dual-port protocol converter designed to reliably translate Modbus RTU/ASCII data to Modbus TCP. This device acts as a transparent gateway, allowing Modbus TCP masters to communicate directly with serial slave devices as if they were native Ethernet endpoints. Its robust hardware and versatile design ensure dependable data connectivity and interoperability in complex industrial environments.

Powered by a high-end CPU, the SC10MK2-485 MT is the ideal choice for demanding applications, including the integration of Energy Meters, Solar controls, Distributed Control Systems (DCS), Programmable Logic Controllers (PLCs), and Human-Machine Interfaces (HMIs). By providing a powerful and efficient conversion mechanism, it unlocks the value of legacy assets and facilitates their integration into modern IIoT and data acquisition platforms. This datasheet outlines the key features and technical specifications that make this converter a superior choice for industrial connectivity.
