Basic Product Information

Project Content

Brand GE (General Electric)

Model IS200WROBH1AAA

Mark VI Series/Mark VI Series

Type: Relay Fuse and Power Sensing Board

Revision level A (functional revision x 2, artwork revision x 1)

Origin: United States

core functionality

1. Main functions

Power distribution management: responsible for primary power management of cabinets or a group of cabinets

Branch circuit allocation: allocate the core output to specific circuits inside the cabinet for consumption

Relay protection: As the fuse and power sensing card of WROB relay, responsible for the safety protection of the relay part

Power sensing: power detection and feedback for branch circuits

2. System architecture

System Function Description

The core part of power distribution in the core distribution system

Branch circuit components allocate core outputs to specific circuits

The feedback method branch circuit has an independent feedback method, which is different from PPDA I/O pack

technical parameters

System compatibility and configuration

1. Supporting modules

Supporting board description

TDBS board can be used in conjunction with TDBS board

SRLY board can be used in conjunction with SRLY board

TDBT board installed on TDBT board in TMR application

2. Redundant configuration mode

Configuration Mode Description

The simplex mode can be used as a TRLY relay creation device in simplex mode

Dual redundancy mode supports dual controllers and dual network systems

TMR (the third mock examination Redundancy) supports triple redundancy mode to achieve maximum fault detection and availability

3. TMR application functions

In TMR applications, the WROB board is installed on the TDBT board

Can provide equivalent terminal board functionality combined with TBCI (contact input terminal board)

When connected to the TDBS board, the relay part can be converted to the same potential as the IS22TRLYH1B board

Provide induction and fuse power distribution for the first six relay outputs

Provide dedicated power supply for the last relay output

Precautions

Notes on Precautions

This board is considered outdated, but can still be found in both old and new spare markets

There are few original technical documents available online, and information needs to be obtained through manuals and visual inspections

There are variant models such as IS200WROBH1A and IS200WROBH1ABA for model differentiation, and their functions may be slightly different

Fuse replacement. Each fuse comes with a factory printed label for easy identification
