Signal Routing & Conversion
The IS200ISBEH1ABC includes a bypass relay that switches transmit signals between P1A, P1B, and P2. When 24 Vdc is present and the interlock is closed, the board routes signals through electrical-to-optical converters. If power is lost, it reroutes optical input from P3 to P2, maintaining communication integrity.
Power & Interface Design
The onboard dc-dc converter accepts 18–36 Vdc and supports up to 5 watts of input power. The board features multiple connectors for full-duplex input, auxiliary data, and fiber-optic transmission, ensuring flexible integration with GE control modules.
Application & Compatibility
The IS200ISBEH1ABC is ideal for turbine control systems requiring robust ISBus communication and node bypass capabilities. It ensures reliable data flow across fiber-optic and electrical interfaces, even during power loss or interlock faults.
