Let’s dive into the world of the YOKOGAWA ALE111-S51 and discover how it can enhance your industrial operations.

Technical Parameters of YOKOGAWA ALE111-S51

Understanding the technical specifications of the ALE111-S51 is crucial for assessing its suitability for specific applications. Below, we break down each parameter to provide a clearer picture of what this module offers:

Physical Layer Interface: IEEE802.3 10BASE-T

The ALE111-S51 utilizes the IEEE802.3 10BASE-T standard for its physical layer interface. This standard is widely adopted in Ethernet networks, ensuring compatibility with a broad range of devices and systems. The 10BASE-T specification supports data transmission at 10 Mbps, which is sufficient for most industrial communication needs.

Connection Method: Point-to-Point

The module employs a point-to-point connection method, meaning it establishes a direct link between two devices. This setup is ideal for scenarios where a dedicated communication channel is required, minimizing interference and ensuring data integrity.

Connector: RJ-45

Equipped with an RJ-45 connector, the ALE111-S51 uses the standard Ethernet port found on most networking equipment. This commonality simplifies the integration process, as it allows for the use of standard Ethernet cables and reduces the need for specialized connectors.

Transmission Method: Half-Duplex

The transmission method is half-duplex, which means data can be sent and received, but not simultaneously. While full-duplex communication is faster, half-duplex is often sufficient for many industrial applications where real-time data exchange is not critical.

Communication Functions: Modbus and DNP3 Protocols

One of the standout features of the ALE111-S51 is its support for Modbus and DNP3 communication protocols. Modbus is a widely used protocol in industrial automation for connecting different devices, while DNP3 is particularly popular in the utilities sector for its robustness and security features. This dual support makes the module versatile and adaptable to various industry requirements.

These technical parameters collectively make the ALE111-S51 a powerful tool for industrial communication, offering reliability, compatibility, and flexibility.
