Product Details
IONet Switches IS420ESWAH3A supports the GE IONet series of industrial communication protocols, which optimizes real-time data exchange and helps achieve response and coordination among various units of the control system. It is typically deployed at the core of the control network and transmits data between the controller and the field modules.
The port configuration of IS420ESWAH3A mainly includes:
8 10/100Base-TX copper cable RJ-45 ports: Provide standard Ethernet cable interfaces, supporting automatic speed negotiation (10/100 Mbps) and full/half duplex modes. New-Gen Automation Limited
No standard optical fiber port: Unlike some models with optical fiber uplinks, the IS420ESWAH3A version mainly uses copper cable ports for communication; some market versions may expand the fiber connection capability through additional modules.

No standard optical fiber port: Unlike some models with optical fiber uplinks, the IS420ESWAH3A version mainly uses copper cable ports for communication; some market versions may expand the fiber connection capability through additional modules.

GE's product line of industrial, unmanaged Ethernet 10/100 switches, ESWA and ESWB, is specifically designed to meet the needs of real-time industrial control solutions and is required for all IONet switches used in a Mark* VIe and Mark VIeS Safety control system. To meet the requirements for speed and functionality, the following features are provided:
• 802.3, 802.3u, and 802.3x compatibility
• 10/100 base copper with auto negotiation
• Full/half duplex auto-negotiation
• 100 Mbps FX uplink port • HP-MDIX auto sensing
• LEDs to indicate the status of Link Presence, Activity, and Duplex, and Speed per port (each LED has two colors)
• LED to indicate power status
• Minimum 256 KB buffer with 4 K media access control (MAC) addresses
• Redundant power supply inputs (Diode-OR'd)
IS420ESWAH3A Flow Control (Pause)
The switch supports flow control between switches. It uses usesIEEE®-definedd pause packets to receive and honor pause packets. The switch only sends the pause packets if it needs flow control on a port.
IS420ESWAH3A Reliability and Performance
Because high reliability is critical to any controls solutions business, the switch exceeds 4 million hours Mean Time Between Failures (MTBF) at 35°C (95 °F) ambient temperature, ground fixed controlled environment. The switch also meets the following performance criteria:
| Item | Description |
| Switch latency | Switch packet latency does not exceed required application limits. |
| Switch architecture | The switch supports store-and-forward architecture, providing high data confidence. |
| Inrush current | The switch provides soft start capability that limits inrush current to less than 200% of the normal operating current. |
| Mounting | The switch enclosure can be panel-mounted (switch mounts to the rear wall of the panel with a bracket) or DIN-rail mounted. DIN-rail mounting meets vibration and shock specifications. User connections are freely accessible with both mounting types. |
| Power connection | Supports two redundant diode-OR'd power supply inputs of 18 to 36 V dc |
| Cooling | Convection-cooled when mounted vertically or horizontally |
| Coating | Resistant to corrosion with provisions made for grounding per IEC 60721-3-3 Class 3C2 |
| Operating temperature | -30 to 65°C (-22 to 149 °F) |
| Shipping, storage temperature | -40 to 85°C (-40 to 185 °F) |
| Humidity | Operates in a 5 to 95% relative humidity non-condensing environment without any external temperature or humidity excursions |
| Seismic Vibration | Meets Universal Building Code (UBC) |
