Z-KEY-2ETH IEC 61850: ModBUS IEC 61850 Gateway, 2 Serial Ports, 2 Ethernet (SINGLE CLIENT). Includes DIN rail for dual ETH port use.

The **Z-KEY-2ETH IEC 61850** is a **Modbus<->IEC 61850** gateway that allows integration between the Modbus protocol, used in industrial contexts for communication between devices such as PLCs, sensors, and actuators, and the **IEC 61850** standard, designed for communication in electrical substations and energy automation systems. Equipped with **two serial ports** and **two Ethernet ports**, the Z-KEY-2ETH IEC 61850 acts as a translator between the two protocols, allowing Modbus-based devices to communicate with IEC 61850-compliant systems. This is particularly useful in energy automation applications, where **secure, reliable communication** and interoperability between control and protection devices in substations are essential. The gateway allows integrating existing Modbus infrastructures with modern IEC 61850 systems, supporting real-time data collection, processing, and distribution for **advanced monitoring and control** of electrical grids, thereby improving the efficiency and safety of energy processes.

**Note: KEY series devices support up to a single IEC 61850 client. To interact with multiple clients simultaneously, EDGE TWS or PASS Series devices can be used.**
