GE IS410TRLYS2F Mark VIeS Relay Output with TMR Contact Voting

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.

Functional Description

The Analog I/O pack (PAIC) is an electrical interface that connects one or two I/O Ethernet networks to an analog input terminal board. 

The PAIC includes a BPPx processor board as well as an acquisition board dedicated to the analog I/O function.

The module has ten analog inputs. The first eight inputs can be set to 5 V or 10 V or 4-20 mA current loop inputs. 

The final two inputs can be set to 1 mA or 4-20 mA current inputs.

The load terminal resistors for current loop inputs are located on the terminal board, and the PAIC senses voltage across these resistors. 

PAICH2 has two current loop outputs ranging from 0 to 20 mA.

 It also includes additional hardware that allows for 0-200 mA current on the first output only.

The I/O pack receives and sends data to the controller via dual RJ-45 Ethernet connectors and is powered by a three-pin connector. 

Field devices are communicated with via a DC-37 pin connector that connects directly to the associated terminal board.

LED indicator lights provide visual diagnostics.
