GE IS230TCYATH1A - TCAT ASSEMBLY / CORE ANALOG

Industrial Ethernet /IONet Switches

GE’s productline of industrial, unmanaged Ethernet 10/100 switches, ESWA and ESWB,

are specifically designed to meet the needs of real-time industrial control solutions and are 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 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)

The GE Ethernet/IONet switches are available in two hardware forms: ESWA and ESWB. 

Each hardware form is available in five versions (H1A through H5A)that vary in fiberoptic port configuration options, 

which include no fiber ports, multi-mode fiber ports,or single-mode (longer distance) fiber ports. 

Refer to the IS420ESWAH#A IONet Switch Specifications table and the IS420ESWBH#A IONet Switch Specifications table for these fiber option details.

The Mark * VIeS Functional Safety System reflects GE’ s  experience of three-plus decades, 

four generations, and over 10,000 installed Triple Modular Redundant(TMR) systems. 

The Mark VIeS is certified to IEC 61508 standards to meet the  needs of the majority of safety requirements – SIL 2 and SIL 3.

A proven and safe solution

GE brings decades of domain expertise to the Mark VIeS Functional Safety

System. The Mark series of controllers has earned a reputation for superior running 

reliability and superior tripping reliability when required in thousands of TMR 

systems installed in power generation and infrastructure applications globally. These 

proven philosophies are atthe heart of the Mark VIeS Functional Safety System.

Flexibility and reliability Redundancy is a critical feature in safety control system design,

enabling continuous process operation during system maintenance or repair. 

The Ethernet backbone of the Mark VIeS Functional Safety System allows each segment of the system to be configured with different levels of redundancy as follows:

• Can be: Simplex, Dual, or TMR

• I/Onetwork (IONet) communications can be: Simplex, Dual, or TMR

• I/O modules can be: Simplex or TMR This flexibility enables customers to design 

their system to meet the exact needs of their SIL application requirements, and ultimately reducing system costs. 

Customers can customize the level of redundancy to meet safety and running reliability needs.
