ISBus Communication Features
The GE IS200EISBH1A uses a proprietary ISBus protocol for exciter control. This bus operates at 10 Mbps for high-speed data exchange. Therefore, the board provides real-time communication between exciter components. The isolation transformer provides 2500V RMS isolation from the field circuits. Consequently, the module protects sensitive logic from high-voltage transients.
Serial Communication Features
This exciter board offers two serial ports for external device connections. One port supports RS-232 for programming and diagnostics. The other port handles RS-485 for multi-drop instrument networks. Hence, the GE IS200EISBH1A connects to HMIs, programmers, and field devices easily. The baud rate adjusts from 9600 to 115200 bps for flexible integration.
Processing and Energy Storage
The 32-bit RISC communication processor manages all data routing tasks. This processor handles protocol conversion between ISBus and serial interfaces. Therefore, external devices see a standard serial connection while the exciter uses ISBus. The two 47µF tantalum capacitors provide 8 milliseconds of hold-up time. Thus, the GE IS200EISBH1A maintains communication during minor voltage sags.
Installation and Connectivity
You can mount the GE IS200EISBH1A on a standard DIN rail. Alternatively, secure it with M4 screws through its four mounting holes. The ISBus port connects to the exciter backplane via a dedicated cable. The RS-232 port uses a 9-pin D-sub connector for easy wiring. The RS-485 port uses a 3-pin terminal block for network connections. The GE IS200EISBH1A works seamlessly with the RMS-TSG-TZ-C static trip unit.
Environmental Durability
This exciter ISBus board operates reliably from -20°C to +60°C. It also withstands 95% relative humidity without condensation. The board survives vibration up to 2g from 10 to 500 Hz. Therefore, the GE IS200EISBH1A suits demanding power generation environments perfectly.
