IS200WROBH1A

Product Description

The IS200WROBH1A board is a WROB Relay Fuse and Power Sensing Board; part of the Mark VIe Series produced by General Electric. This board is known as an option board that can be used with several other boards in the series, all of the boards are used in the PDIO Discrete Input/Output Module, and the boards which the WROB can attach to are the TDBS, SRLY, and the TDBT boards. This board can be used in simplex or triple-modular redundant (TMR) modes. When this board is being used in TMR applications the WROB board will mount on the TDBT board and can provide the equivalent of a terminal board combined with a contact input terminal board (TBCI).

When the IS200WROBH1A board connects to the TDBS board it has the ability to turn the relay portion into a potential equivalent to that of the IS20TRLYH1B board. With this option, it provides sensed and fused power distribution to the first six initial relay outputs as well as dedicated power to the final relay outputs. This board will also have a default fuse value of three-point-fifteen amperes. When the board is used with the isolated voltage on the TDBS it will be used to detect different statuses of the fuses on the six fuse pairings on the board.

While the IS200WROBH1A board is considered obsolete it can still be found in new and used surplus.
