IS200WROBH1A WROB RELAY FUSE AND POWER SENSING BOARD

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).

Overview

Essential details：IS200WROBH1A WROB RELAY FUSE AND POWER SENSING BOARD

DESCRIPTION

IS200WROBH1A is a Power Distribution Board under the Mark VI series. GE created the board as part of their Speedtronic range. The Mark control platform offers scalable redundancy levels. A single (simple) controller with simplex I/O and a single network is the foundation of the system. The dual system has two controllers, singular or fanned TMR I/O, and dual networks, which increases reliability and allows for online repairs. Three controllers, singular or fanned TMR I/O, three networks, and state voting amongst controllers make up the TMR system, which allows for maximum fault detection and availability.

The core distribution system and branch circuit elements are two distinct types in the PDM. They are responsible for a cabinet’s or a set of cabinets’ primary power management. The branch circuit elements take the core output and distribute it to specific circuits in the cabinets for consumption. Branch circuits have their own feedback methods that are not included in the PPDA I/O pack’s feedback. IS200WROBH1A is a Relay Fuse And Power Sensing card from WROB. The card has twelve fuses on it. The fuse has a 3.15 A rating and is rated for 500VAC/400VDC.

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. If you have any questions regarding the availability of this board, please reach out to our sales team during normal business hours Monday through Friday to receive quotes on pricing, repairs, and shipping times.
