The GE DS200SNPAH1A DS200SNPAH1ABB provides SNP protocol communication for Mark V turbine systems. This interface board connects the turbine controller to external devices and networks. It supports point-to-point and multidrop configurations for flexible system design. Weighing only 0.32 kg, the GE DS200SNPAH1A DS200SNPAH1ABB mounts inside Mark V control cabinets. Its dimensions measure 220 mm x 130 mm x 25 mm.
Communication Specifications and Protocol Features
The GE DS200SNPAH1A DS200SNPAH1ABB supports SNP (Series Ninety Protocol) for GE controller communication. This interface board provides RS-232 and RS-485 physical layer connections. It handles baud rates from 9,600 to 115,200 for flexible network speeds. Moreover, the GE DS200SNPAH1A DS200SNPAH1ABB includes optical isolation between the controller and communication lines. Consequently, it protects the turbine control system from ground loops and electrical noise.
Energy Storage and Diagnostic Features
The GE DS200SNPAH1A DS200SNPAH1ABB contains no internal battery for maintenance-free operation. This board draws 150 mA from the 5 V DC and 24 V DC power supplies. It includes LED indicators for power, transmit, receive, and fault status. The GE DS200SNPAH1A DS200SNPAH1ABB features test points for signal verification during troubleshooting. Therefore, technicians can diagnose communication issues without disconnecting cables.
