IS200WROBH1A GE Mark VIe, WROB Relay Fuse and Power Sensing Board

Description:

The IS200WROBH1A board is a WROB (Watchdog Relay, Overload, and Breaker) module that includes relay, fuse, and power sensing capabilities. It is part of the Mark VIe Series manufactured by General Electric (GE). This board serves as an optional component that can be integrated with several other boards within the series. All these boards are utilized in the PDIO (Programmable Discrete Input/Output) module, and the WROB can be connected to TDBS (Telecommunications Data Bus Submodule), SRLY (System Relay), and TDBT (Terminal Board and Contact Input Terminal Board) modules. The WROB board is versatile and can operate in either simplex or triple-modular redundant (TMR) configurations. In TMR setups, the WROB board is mounted on the TDBT and functions similarly to a combination of a terminal board and a contact input terminal board (TBCI).

When interfaced with the TDBS board, the IS200WROBH1A has the capability to transform the relay section to mimic the functionality of the IS20TRLYH1B board. With this configuration, it offers monitored and protected power distribution to the first six primary relay outputs, along with dedicated power to the subsequent relay outputs. The board is also preset with a default fuse rating of three-point-fifteen amperes. When paired with isolated voltage on the TDBS, it is designed to detect various states of the fuses across the six fuse pairings on the board.
