GE IS200VSV0H1BED – Vibration Sensor Interface Board | Mark VI Turbine Control Platform
Engineering Background
The GE IS200VSV0H1BED is a vibration sensor interface board engineered for GE’s Mark VI turbine control system — one of the most widely deployed distributed control architectures in gas turbine, steam turbine, and combined-cycle power generation facilities worldwide. The VSV (Vibration Sensor Voting) board serves as the critical signal conditioning and voting logic layer between field-mounted proximity probes or accelerometers and the Mark VI’s TMR (Triple Modular Redundancy) processing core.
Product Positioning
Designed for procurement engineers and reliability teams responsible for maintaining continuous turbine operation, the IS200VSV0H1BED provides direct drop-in replacement capability for aging or failed VSV boards without requiring system reconfiguration. Its role in the vibration monitoring chain makes it a tier-1 critical spare for any facility operating GE Frame 6, Frame 7, Frame 9, or LM-series gas turbines under Mark VI supervision.

Engineering Advantages
- TMR Fault Tolerance: Voting architecture prevents spurious trips caused by single-channel sensor or board faults, maintaining turbine availability during partial failures.
- Direct Replacement: Pin-compatible with existing Mark VI VSV slots — no firmware re-flash or I/O configuration change required for same-revision swap.
- Signal Integrity: On-board signal conditioning filters and amplifies raw proximity probe signals before digitization, reducing susceptibility to EMI common in turbine hall environments.
- Diagnostic Transparency: Board-level diagnostics are surfaced through the Mark VI HMI (ToolboxST), enabling maintenance teams to isolate faults to the channel level without physical inspection.
- Long Service Life: Industrial-grade components rated for continuous duty in high-vibration, high-temperature environments typical of turbine enclosures.
System Architecture & Signal Flow
In a Mark VI TMR configuration, three IS200VSV0H1BED boards operate in parallel — one per control path (R, S, T). Each board independently conditions and digitizes vibration signals from shared field sensors. The digitized values are transmitted over IONet to the VCMI (VME Communication Module Interface) and then to the VTUR/VCOR processing modules, where the 2oo3 voting algorithm determines the authoritative vibration value used for protection and control logic. A single board failure is self-announcing and non-tripping in TMR mode, allowing planned maintenance without forced outage.
Sourcing & Quality Verification

Technical FAQ
Q: Is IS200VSV0H1BED compatible with Mark VIe?
A: The IS200VSV series was designed for Mark VI. Mark VIe uses a different I/O architecture (ETM/EtherNet-based). Cross-compatibility requires engineering review — contact us before ordering for a Mark VIe application.
Q: Can this board be used in a Simplex (non-TMR) Mark VI configuration?
A: Yes. The IS200VSV0H1BED operates in both TMR and Simplex Mark VI racks. In Simplex mode, voting logic is bypassed and the single board output is used directly.
Q: What proximity probe types are supported?
A: The board is designed for Bently Nevada-compatible 3300 series and equivalent eddy-current proximity probes (standard -24 VDC bias). Verify your probe driver output range against GE IS200VSV application notes before installation.
Q: Do you provide a test certificate?
A: Yes. A functional test report is included with every unit shipped from Konmask.com.
Q: What is the return policy?
A: 30-day return window for unused, uninstalled units in original packaging. Contact support@konmask.com to initiate.
