The IS200ISBEH1A board component is part of the Mark VI Speedtronic system from General Electric. One of the final industrial Speedtronic control systems released by GE, the Mark VI was designed as a complete control/protection/monitoring system that could meet the needs and requirements of industrial gas and steam turbines. This system is built with a PC_based HMI operator interface that uses a Microsoft Windows platform preloaded with GE’s proprietary CIMPLICITY software. The HMI can be reinitialized or replaced with no impact to processes running elsewhere on the system.
The IS200ISBEH1A functions as an ISBus Extender board. It typically connects directly to the J11A interface on the CAPB Control Assembly Backplane board, where it is used to connect that board to higher-level controllers like an ACL_ board. The board can also mate with the J12A interface on the same board.
The IS200ISBEH1A is built upon DIN rails. The board has six inputs/outputs located on opposite board edges. Each board edge includes a small terminal strip, while one side has two plug connectors and the other edge has two fiber-optic connectors. In between these edges, the board is populated by integrated circuits, LED indicators (red, yellow, and green), a jumper switch to set bypass/unbypassed, capacitors, resistors, and diodes. Most components are marked. The board is marked with its board ID and also carries several other codes.
Additional information about proper installation techniques, maintenance, and handling can be found through original documentation like manuals and user guides provided by the OEM.
