I/O modules

Key Technical Specifications

This GE IS420ESWAH1A module operates from a 24V DC power supply. It provides 8 Ethernet switch ports for IONet communication. The unit measures 20 cm in length, 15 cm in width, and 3.5 cm in height. Its total weight equals 0.55 kg without any packaging materials.

The GE IS420ESWAH1A includes 8 RJ45 ports with auto-negotiation. Additionally, it features one backplane connector for system integration. A single 4-pin terminal block connects the DC power input. The module contains 1 switch controller, 8 transformers, 8 status LEDs, 2 voltage regulators, 12 resistors, and 10 capacitors.

GE IS420ESWAH1A stores energy using one electrolytic capacitor. This capacitor provides 22 µF at 35V rating for transient filtering. Consequently, the module maintains network connectivity during 10 millisecond power interruptions. Therefore, data packets remain intact through brief voltage dips.

Design and Integration

This IONet switch module uses four-layer PCB construction with isolated port banks for noise immunity. Consequently, the GE IS420ESWAH1A operates reliably from -10°C to +55°C ambient temperature.

For installation, you need M3 screws for the four mounting holes. The module draws 150 mA typical current from the 24V DC supply. Each port supports auto-MDI/MDIX for flexible cabling. We recommend using shielded Ethernet cables for all network connections.

Practical Application

This IONet switch module connects turbine control devices in a redundant network architecture. It links I/O packs, controllers, and operator workstations. The GE IS420ESWAH1A also provides diagnostic LEDs for each port. Therefore, it serves as the communication backbone for GE Mark VIe control systems.
