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. World of Controls has the most comprehensive selection of GE Speedtronic Mark VI control replacement components.
