Product Name:

GE IS420ESWBH2A/IS420ESWBH3A Ethernet IONet Switch

Product Description:

• Both are unmanaged industrial Ethernet switches designed for GE’s Mark VIe control systems. They provide reliable, deterministic communication for real-time control applications   
• “Unmanaged” means they are plug-and-play, requiring no configuration.   
• They are designed for harsh industrial environments.

Key Differences between IS420ESWBH2A and IS420ESWBH3A:

This is where it gets tricky. Official, detailed datasheets directly comparing these specific models are not readily available publicly. However, based on information gathered from various sources, here’s what we can deduce:

• IS420ESWBH2A:
  • 16 x 10/100Base-TX copper ports (RJ-45)   
  • 2 x 100Base-FX multi-mode fiber ports (LC-type)
• IS420ESWBH3A:
  • Likely has a similar number of copper ports (16 x 10/100Base-TX)
  • The key difference is in the fiber ports. It seems the H3A might have:
    • More fiber ports: Possibly 4 or more.
    • Different fiber type: Potentially Gigabit or single-mode fiber, offering higher bandwidth or longer distance capabilities compared to the H2A’s multi-mode.
    • No fiber ports at all: Some sources suggest the H3A might be a purely copper switch, focusing on a higher density of copper connections.

Product Parameters and Specifications (General for both, with known differences):

• Number of Ports:
  • H2A: 16 copper + 2 fiber
  • H3A: Likely 16 copper, fiber configuration varies (possibly 0, 4, or more of a different type)
• Port Type:
  • 10/100Base-TX (copper, RJ-45)
  • 100Base-FX (multi-mode fiber, LC-type) – H2A
  • H3A fiber: Possibly Gigabit or single-mode, or none
• Switching Technology: Store-and-forward
• Power Requirements: 24/28 VDC, 1A max   
• Operating Temperature: -40 to 70°C (-40 to 158°F)  
• Mounting: DIN-rail mountable
• Dimensions: Approximately 18.8 x 8.6 x 5.6 cm (7.40 x 3.40 x 2.20 in)  

Product Use:

The core use is the same for both:

• Connecting Devices: Linking controllers, I/O modules, HMIs, and other devices within the Mark VIe control network.
• Facilitating Communication: Enabling data exchange within the control system.
• Ensuring Real-Time Performance: Providing reliable communication for time-critical control applications.

Applications:

• Power Generation (gas turbine, steam turbine, combined cycle)
• Oil and Gas (refineries, pipelines, offshore platforms)
• Other Industrial Processes

Key Features and Benefits (General):

• Industrial Grade
• Unmanaged Operation (plug-and-play)
• Real-Time Performance
• Fiber Optic Options (more varied on the H3A)
