The IS200TVBAH2A (including the IS200TVBAH2ACC variant) is a high-performance vibration termination board designed for the GE Speedtronic Mark VI control system. It serves as the physical interface for seismic, proximity, and acceleration sensors, providing essential signal conditioning and transient protection before routing data to the vibration processor (VVIB) modules.

Product Q&A
-
Q: What is the purpose of the IS200WNPSH1ABA modules in this set?
-
A: The WNPS modules are localized power supplies that provide regulated voltage specifically for the transducers connected to the termination board.
-
-
Q: Does the “ACC” suffix indicate a special feature?
-
A: The “CC” typically stands for Conformal Coating, providing superior resistance to moisture and chemical contaminants in industrial environments.
-
-
Q: Is this board compatible with Mark VIe systems?
-
A: No, the IS200 series is specific to the Mark VI VME-based architecture; the Mark VIe uses the IS215/IS220 series.
