Introduction

The SC10E4I MK 502 is a high-performance, 4 Port Isolated Modbus RTU to Modbus TCP Gateway. It is specifically designed to facilitate seamless protocol conversion and data exchange between serial-based industrial devices—such as PLCs, meters, and sensors—and IP-based Ethernet networks. By translating Modbus RTU commands from its serial ports to Modbus TCP on its Ethernet port, it allows TCP Masters to control and monitor RTU Slaves transparently across the network.

At its core, the device functions as a versatile communication hub, ensuring that critical data from the factory floor is accessible to higher-level management and control systems. Its rugged metal housing, extensive electrical protection, and wide operating temperature range make it exceptionally well-suited for deployment in demanding industrial environments where reliability is paramount. Whether operating as a TCP Server, TCP Client, RTU Master, or RTU Slave, the SC10E4I MK 502 provides the flexibility required for complex industrial control system architectures.

The gateway's performance is founded on a powerful hardware platform featuring a 580 MHz MIPS CPU, 128MB of DDR2 RAM, and a flexible OpenWrt Linux operating system. This combination ensures efficient protocol handling, stable network communications, and the capacity to manage multiple simultaneous requests without performance degradation.

These capabilities are enabled by a set of high-impact features designed to deliver superior connectivity, protection, and operational flexibility, differentiating the SC10E4I MK 502 in the industrial networking market.
