• Turbine control networks (Gas and Steam).
• Industrial process control for steel, building materials, and non-ferrous metal production.
• Critical infrastructure including water treatment and large-scale heating systems.

Technical Specifications

Installation Guidelines

• Ensure the module is installed in a clean, dry, and well-ventilated cabinet to maintain the specified operating temperature range.
• Use shielded twisted-pair cabling for copper ports to minimize EMI interference in industrial environments.
• Verify that the power supply meets the 24/28 V dc requirements and is properly grounded before connection.
• Handle fiber optic LC connectors with care to prevent dust contamination; use protective caps when ports are not in use.
• Always power down the system before inserting or removing the module from the rack to prevent electrical arcing or damage to the backplane.

FAQ

What is the primary function of the IS420ESWBH2A?

It serves as an industrial Ethernet switch within the GE Mark VIe control platform, facilitating reliable data communication between controllers, I/O modules, and supervisory systems.

Does this switch support fiber optic connections?

Yes, it includes two 100Base-FX multi-mode fiber optic ports with LC-type connectors, which are ideal for longer distance network runs compared to standard copper cabling.

Is this device suitable for hazardous environments?

Yes, the IS420ESWBH2A is rated for use in hazardous locations, including Class 1, Div 2, Class 2, Zone 2, and ATEX-certified areas.

How does the switch handle inrush current?

The unit features a soft-start mechanism that limits inrush current to less than 200% of the normal operating current, protecting the power distribution system during startup.
