Part number: IS200WROBH1A
Manufacturer: General Electric
Product type: Power distribution board
Series: Made by Mark VI
Country/region: USA
The IS200WROBH1A board is the WROB relay fuse and power sensing board, part of the Mark VIe series produced by General Electric. The board is called an optional board and can be used with several other boards in the series, all for PDIO discrete input/output modules, and the boards WROB can connect to are TDBS, SRLY and TDBT boards. The board can be used in simplex or three-mode redundancy (TMR) modes. When the board is used for TMR applications, the WROB board will be mounted on the TDBT board and an equivalent terminal board is available in combination with the contact Input terminal Board (TBCI).
When the IS200WROBH1A board is connected to the TDBS board, it is able to convert the relay portion to a potential equivalent to that of the IS20TRLYH1B board. With this option, it provides induction and fuse power distribution for the first six initial relay outputs and dedicated power for the final relay output. The default fuse value for this board is 3.15 amps. When the board is used with the isolation voltage on the TDBS, it will be used to detect the different states of the fuses on the six fuses pairs on the board.
