Configured for high-speed data routing and discrete contact execution in Mark VI turbine control system platforms, the GE IS200REBFH1BBA (IS200REBF Ethernet Interface Board) provides direct physical/electrical execution. The module manages determinism across network links via dual redundant Ethernet interfaces while accommodating local dry-contact execution through 16 Form C relay output channels. Onboard diagnostic LEDs deliver real-time feedback for power rail stability, port link integrity, and active packet transactions.

The IS200REBFH1BBA optimizes backplane bus communication velocity across the Mark VI control rack by offloading protocol processing directly at the interface module layer. Through native execution of TCP/IP and UDP packet framing over dual redundant Ethernet channels, the module isolates external network traffic from core executive scan cycles. This distributed communication handling ensures firm firmware flash compatibility across Mark VI node revisions while maintaining precise I/O density scaling for Form C relay output commands.
Q: How does the dual redundant Ethernet port architecture operate on the IS200REBFH1BBA?
A: The board provides two isolated physical Ethernet interface channels that execute simultaneous network data exchange using TCP/IP or UDP, maintaining link availability if one network path fails.
Q: What contact output configuration is supported by the onboard relays?
A: The module contains 16 Form C relay outputs, offering single-pole double-throw (SPDT) dry-contact switching for discrete field device control.
Q: What are the input voltage requirements for powering the IS200REBFH1BBA board?
A: The module operates from a nominal 24 VDC power supply bus routed through the rack structure or dedicated power header.
Our production line was down due to a faulty Bently Nevada monitor. We found it in stock here and they shipped it via DHL immediately. Back in operation within 48 hours—truly a lifesaver for our plant.
