Features:
- IS420ESWBH3A provides 16 unmanaged 10/100 Ethernet ports with auto-negotiation and redundant power inputs.
- HP-MDIX auto-sensing eliminates crossover cables; 100 Mbps FX uplink supports fiber connectivity options.
- DIN-rail mountable with 256KB buffer, 4K MAC table, and IEEE 802.3/802.3u/802.3x compliance.
The IS420ESWBH3A delivers 16 high-speed 10/100Base-T copper ports specifically engineered for industrial control networks. Each port supports auto-negotiation, automatically detecting and configuring the optimal speed (10 or 100 Mbps) and duplex mode (half or full) based on the connected device. This plug-and-play capability simplifies installation and reduces configuration errors. The unmanaged design means the switch operates without user configuration—no IP addresses, VLANs, or spanning tree settings are required—making it ideal for deterministic real-time control networks like GE's IONet.
The IS420ESWBH3A incorporates redundant power supply inputs using diode-OR'd circuitry, a critical feature for high-availability control systems. Two separate power sources can be connected to the switch; if the primary supply fails, the secondary supply automatically takes over without any interruption to switch operation. This redundancy eliminates the power supply as a single point of failure, ensuring continuous network communication even during power source maintenance or failure events. The HP-MDIX (Automatic MDI/MDI-X) feature on all copper ports eliminates the need for crossover cables. The switch automatically detects whether a connected device uses straight-through or crossover wiring and adjusts its internal signal routing accordingly.
The IS420ESWBH3A is designed for easy integration into standard industrial control cabinets using DIN-rail mounting. GE provides three qualified mounting clip options: 259B2451BVP1 for ESWB switches mounted with the long edge parallel to the rail, and 259B2451BVP4 for perpendicular orientation. Mounting screws are included with each switch, simplifying installation. The switch is available in multiple hardware versions (H1A through H5A) that differ in fiber optic port configuration. Options include no fiber ports (all copper), multi-mode fiber ports for distances up to 2 km, or single-mode fiber ports for longer distances up to 15 km or more.
The IS420ESWBH3A GE Ethernet Switch may still be available for purchase and support from Apter Power beyond
End-Of-Life (EOL) by the manufacturer (OEM).

- Power Generation (Turbine Control): Broadly used in GE distributed gas turbine and steam turbine control architectures. It handles high-priority operational inputs, configurations, and redundancy information.
- Safety Instrumented Systems (SIS): Certified for use in the Mark VIeS Functional Safety System. It establishes a secure network topology for emergency shutdowns and fire/gas isolation loops.
- Heavy Process Automation: Installed in petrochemical plants, oil and gas pipelines, and large scale manufacturing units requiring sub-millisecond control loop response times.
- Network Redundancy Structures: Serves as the core hub for Simplex, Duplex, or Triple Modular Redundancy (TMR) architectures, preventing localized networking failures from tripping a plant.
- Ambient Temperature: Operational from -40°C to 70°C (-40°F to 158°F). (Storage/shipping limits extend from -40°C to 85°C).
- Humidity Limits: Operates within 5% to 95% relative humidity, non-condensing.
- Chemical/Corrosion Resistance: Features a protective conformal coating compliant with IEC 60721-3-3 Class 3C2 and is G3 compliant, allowing deployment near harsh atmospheric pollutants like sulfur or chlorine.
- Hazardous Locations: Certified for use in hazardous areas including Class 1, Div 2 / Class 2, Zone 2 / ATEX environments.
- Port Configuration: Features 16 10/100Base-TX copper RJ-45 ports (no fiber options).
- On-Module Loop Diagnostics (Open/Short & Out-of-Range): The General Electric IS420PUAAH1A continuously checks thermocouples for open circuit, RTDs for open/short, and 4-20mA loops for high (>21.5mA) or low (<3.6mA) faults, immediately flagging sensor failures to ToolboxST.
- Performance: Utilizes a 256 KB buffer with a 4K MAC address table for managing data traffic, including multicast and broadcast packets, ensuring reliable, low-collision communication.
- Functionality: Complies with IEEE 802.3/u/x standards, featuring HP-MDIX auto-sensing for automatic cable detection and configuration.
