        Overview Manuals Hardware Interfaces Vibration Processing Protection Logic Turbine Applications

        Features:

        • High-speed probe processing supports turbine vibration and rotor-position protection calculations.
        • Current-limited excitation helps contain a shorted probe supply without removing every measurement channel.
        • TVIB buffered outputs can feed portable or permanent vibration-monitoring equipment alongside Mark VI protection.
        IS200VVIBH1C derives peak-to-peak vibration from the maximum and minimum signal values collected during each sample period, then filters and scales the result for the configured displacement or velocity measurement.

        In a TMR arrangement, the connected termination hardware can select the highest available -28 V DC bus through a diode high-select circuit. This keeps probe excitation available when one redundant supply path is lower or unavailable.

        Mark VI can present total vibration, the 1X component, and 1X phase angle from IS200VVIBH1C data. The control platform uses those values for monitoring and protection, while detailed vibration analysis remains the role of dedicated condition-monitoring equipment.

        Interfaces That Define an IS200VVIBH1C Replacement

        • Rack relationship: the board occupies the VME processing layer of the Mark VI controller rather than serving as a field termination card.
        • Termination pairing: probe wiring reaches IS200VVIBH1C through the applicable TVIB or DVIB termination arrangement.
        • Sensor assignment: termination-board jumper positions distinguish seismic, Velomitor, Proximitor, and accelerometer paths before signals reach the board.
        • Redundancy layout: simplex and TMR installations use different cable paths between terminal boards and the controller racks.
        • External monitoring: optional TVIB connections can share buffered probe information with Bently Nevada equipment without replacing the Mark VI protection path.

        How IS200VVIBH1C Builds Usable Vibration Data

        • Displacement processing: maximum and minimum samples are subtracted to produce peak-to-peak shaft-motion values.
        • Velocity processing: seismic and Velomitor signals are scaled for velocity monitoring after the selected filtering is applied.
        • Phase reference: a Keyphasor pulse gives the controller a once-per-revolution reference for 1X magnitude and phase.
        • Position tracking: DC gap information supports axial-position and eccentricity calculations in addition to dynamic vibration.
        • Controller results: processed values are delivered to the Mark VI logic where limits, alarms, faults, and trips are evaluated.

        Protection Decisions Supported by IS200VVIBH1C

        • System limits: two configurable limit checks can be applied across the board points for monitored gap or motion conditions.
        • TMR comparison: a difference limit identifies disagreement among redundant vibration inputs before voting masks a developing channel problem.
        • Latched response: configured limits can retain an alarm indication so a brief excursion is not lost after the signal returns to normal.
        • Hardware supervision: board diagnostics distinguish operating status from run and fail conditions through the rack-facing indicators.
        • Protective escalation: the controller turns qualified measurement limits into alarm, fault, or trip action appropriate to the configured turbine function.

        Turbine Protection Uses for IS200VVIBH1C

        • Journal-bearing vibration: paired radial proximity probes let IS200VVIBH1C supply shaft displacement information in two directions for alarm and trip logic.
        • Thrust-bearing protection: an axial probe tracks thrust-collar movement so the controller can detect excessive rotor position associated with bearing wear.
        • Differential expansion: non-contact probes measure relative growth between the rotor and turbine casing during thermal changes.
        • Turning-gear eccentricity: once-per-revolution shaft observations support eccentricity monitoring while the turbine rotates slowly on turning gear.
        • Predictive maintenance: buffered TVIB outputs allow portable data collection while IS200VVIBH1C continues feeding the Mark VI protection system.
        Description
        IS200VVIBH1C is a General Electric VME vibration monitor board used in the Mark VI turbine control system to receive, digitize, and forward machinery-condition signals from connected vibration termination hardware. Its position in the VME rack makes it the processing link between field probes and the controller functions that act on vibration and rotor-position information.

        For rotating-equipment protection, IS200VVIBH1C works with proximity, seismic, accelerometer, and Velomitor inputs selected at the termination board. This allows one board arrangement to support radial shaft vibration, axial position, differential expansion, eccentricity, and phase-reference measurements without treating unlike probe technologies as interchangeable.

        Inside the signal path, IS200VVIBH1C converts analog probe returns with a 16-bit converter and transfers the resulting data over the VME bus. Simultaneous sampling and defined time windows keep related channels aligned so the controller can compare motion, position, and Keyphasor information in protection logic rather than relying on isolated readings.

        The IS200VVIBH1C architecture supports simplex and triple-modular-redundant Mark VI arrangements through the applicable TVIB termination-board connections. When planning a replacement, the installed probe types, terminal-board wiring, redundancy arrangement, and rack interface should be documented together because each determines how the vibration channels are presented to the control system.

        Technical notes
        IS200VVIBH1C uses a reduced scan rate when nine or more probes are configured; account for that change when interpreting diagnostic timing.

        FAQS

        The following is a list of questions commonly asked by our customers. Please contact us if you have a question about our process that is not answered below.
        VIEW ALL FAQS
        How can a maintenance team avoid ordering the wrong termination-board combination for IS200VVIBH1C?
        For IS200VVIBH1C, record whether the rack is simplex or TMR, identify each connected TVIB, and capture the probe-type jumper arrangement before removal. Those details determine the cable and channel configuration that must be restored.
        Why might vibration values look plausible while protection behavior is still wrong after an IS200VVIBH1C replacement?
        IS200VVIBH1C processes several probe types whose scaling and protection use differ. A channel assigned to the wrong sensor type can still produce a signal, so compare probe selection, scaling, and controller point configuration rather than checking only for live data.
        Several IS200VVIBH1C channels changed together—where should troubleshooting start?
        Because IS200VVIBH1C samples related inputs simultaneously, a common change across channels may point to shared termination-board power, cabling, or reference conditions. Separate those common causes from a single damaged probe before replacing another board.
        How should a site preserve Keyphasor and phase information when exchanging IS200VVIBH1C?
        IS200VVIBH1C uses the Keyphasor reference with vibration inputs for phase calculations. Keep the reference-probe assignment, polarity, and channel mapping tied to the original configuration so the controller does not lose the intended once-per-revolution relationship.
        What evidence helps distinguish a probe problem from an IS200VVIBH1C channel problem?
        For IS200VVIBH1C troubleshooting, compare the affected channel with another known probe path, inspect the termination-board jumper and probe supply, and use available buffered signals where the installed TVIB provides them. This isolates field hardware from the VME processing path.
        Can IS200VVIBH1C be moved between simplex and TMR racks without additional planning?
        IS200VVIBH1C supports both architectures, but the termination-board cabling and redundant signal paths are arranged differently. Treat an architecture change as a configuration project, not a direct board swap, and document every connected rack channel.
        How can operators reduce false trips after returning IS200VVIBH1C to service?
        After installing IS200VVIBH1C, confirm sensor type, gap or bias condition, scaling, alarm direction, and system-limit settings against the retained site configuration. Then observe stable channels before restoring automatic protection actions.
