The GE IS421ESWAH3A is an 8-port Ethernet switch from the ESW Series for the Mark VIe control system. It is designed to manage high-speed, real-time communication between the main controller and various I/O modules, using copper-based Ethernet connections only, as it has no fiber optic ports. This makes it a cost-effective solution for short-distance network traffic within a control cabinet.
Key Features and Applications
The IS421ESWAH3A is a core part of the Mark VIe’s communication network, offering a straightforward and reliable solution for local data traffic.
- 8-Port Ethernet Switch: The switch serves as a data hub, routing information efficiently between the connected devices. With 8 ports, it can support a significant number of I/O modules, enabling the system to collect a large amount of data from and send commands to field devices.
- Copper-Based Connectivity: This model relies on standard Ethernet cables for all connections. This makes it a more affordable and simpler option for applications where long-distance, EMI-resistant communication isn’t a primary concern. It’s ideal for interconnecting modules within the same control panel or a local area.
- IONet Protocol: The switch operates on the IONet protocol, a proprietary GE network designed for real-time, low-latency control. This ensures that critical data is delivered quickly and reliably, which is vital for the fast response times required in turbine and generator control.
- System Redundancy: In critical applications, these switches can be deployed in redundant pairs. This configuration ensures that if one switch fails, the other can take over seamlessly, preventing communication loss and maintaining continuous control of the system.
Common Applications
The GE IS421ESWAH3A is commonly used in:
- Power Generation: To link turbine and generator control modules to the main processor, particularly within a single control cabinet.
- Oil & Gas: For connecting I/O modules in local control rooms or non-hazardous areas.
- Industrial Plants: In various process control systems where a high-port-count switch is needed for managing data traffic over short to medium distances.
