Reason S20 | Managed Ethernet Switches
GE´s Reason S20 managed Ethernet switch range is designed for harsh environments, such as power systems and industry applications, providing all elements needed in an IEC 61850 digital substation network, including IEEE 1588v2 Precision Time Protocol (PTP).
The Reason S20 series includes the following models:
- S2020, the cost-effective choice, offers a high density of Ethernet ports in a 1U form factor for easy rack mounting. This model supports up to 5 modules with 4 ports each and allows configurations with up to 20 fast Ethernet ports or up to 4 gigabit ports plus 16 fast Ethernet ports.
- S2024, the premium model, offers full gigabit Ethernet switch functionality. This model supports up to 24 ports, provided by 6 interface modules with 4 ports each. The 1U mechanical design is identical to the S2020 model.
GE's Reason S20 series of managed Ethernet switches are designed to enable an IEC 61850 digital substation network, including IEEE 1588v2 (PTP), in harsh environments within power systems and industry applications. Using the Reason S20, packet switching between substation devices is flexible, reliable and robust, even in situations where routing is necessary.
