More Information

Overview Manuals Protection Trip Paths Connections Installation

Features:

  • Independent emergency overspeed protection
  • Triple-redundant VPRO architecture
  • H1B support for a second TREG terminal board
The IS215VPROH1BD ordering code identifies an H1B-form VPRO board for the separate Mark VI Protection Module.

Three VPRO boards operate independently from the turbine control processors and vote on emergency protection conditions before acting on the trip path.

When selecting this code, confirm the installed TPRO, TREG, and TRPG arrangement, especially whether connector J4 serves a second TREG board.
The General Electric IS215VPROH1BD VPRO Emergency Turbine Protection Board is listed as Active / Available from OEM. Apter Power supports official-document review and protection-system matching.

Independent Trip Architecture

  • Protection module: Three VPRO boards form a separate triple-redundant emergency protection subsystem.
  • Overspeed function: Turbine speed signals are evaluated independently for emergency overspeed conditions.
  • Emergency stop: The VPRO logic also processes the emergency-stop path used by the protection module.
  • Controller separation: The protection subsystem operates independently from the turbine control processors.

Terminal-Board Roles

  • TPRO inputs: Passive magnetic speed pickups and other protection signals enter through the TPRO terminal board.
  • TREG control: IS215VPROH1BD controls trip relays located on the TREG terminal board.
  • Positive feed: TREG supplies the positive side of the trip-solenoid circuit.
  • Negative feed: TRPG provides the negative side used to complete the trip-solenoid path.

Front-Panel Interface Map

  • J3 path: Retain the documented J3 cable identity and terminal-board destination during replacement.
  • J4 path: The H1B configuration uses J4 when a second TREG terminal board is installed.
  • J5 and J6: These front connectors must return to their recorded protection-module cable positions.
  • J7 power: Verify the board power connection and rack power state before running diagnostics.

Rack Replacement Sequence

  • Power removal: De-energize the VME rack under the approved site procedure before removing the VPRO board.
  • Board seating: Slide IS215VPROH1BD into the designated slot and use both ejector levers to seat it fully.
  • Mechanical security: Tighten the captive screws after the board is aligned and seated in the rack.
  • Return to service: Restore J3-J7 cabling, review diagnostics, and complete the approved protection trip-verification process.
Description
IS215VPROH1BD is a VPRO Emergency Turbine Protection Board used in the separate Mark VI Protection Module. Three VPRO boards form an independent, triple-redundant protection system for emergency overspeed and emergency-stop functions.

In the protection architecture, IS215VPROH1BD receives turbine speed and additional protection signals through the TPRO terminal board. The VPRO boards vote on trip conditions and control the TREG trip relays, while the TRPG terminal board supplies the negative side of the trip-solenoid circuit.

The H1B hardware form documented for IS215VPROH1BD supports a second TREG terminal board through front connector J4. This distinction matters when an installed protection module uses the additional TREG path; a nearby VPRO form that omits this connection must not be assumed interchangeable.

To install IS215VPROH1BD, power down the VME rack, slide the board into the designated slot, seat the top and bottom levers, and tighten the captive screws. Restore the documented J3 through J7 connections, review board diagnostics, and perform only the approved site trip-verification procedure before returning the turbine protection system to service.

Technical notes
IS215VPROH1BD is an H1B-form VPRO board for independent Mark VI emergency turbine protection. Confirm the full nameplate, TREG arrangement, cabling, and approved trip configuration.

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.
What protection functions does GE IS215VPROH1BD perform?
GE IS215VPROH1BD participates in the independent Mark VI emergency overspeed and emergency-stop protection system.
Why does the H1B form matter when selecting GE IS215VPROH1BD?
The H1B form of GE IS215VPROH1BD supports a second TREG terminal board through J4, so the installed TREG arrangement must be confirmed.
Which terminal boards work with GE IS215VPROH1BD?
GE IS215VPROH1BD uses TPRO for protection inputs, controls trip relays on TREG, and works with TRPG in the trip-solenoid path.
Can an H2B VPRO board automatically replace GE IS215VPROH1BD?
No. GE IS215VPROH1BD has H1B-specific second-TREG support, while the documented H2B form omits that connection.
What should be checked if GE IS215VPROH1BD shows a diagnostic fault?
For GE IS215VPROH1BD, review RUN and FAIL indications, IONet status, rack power, J3-J7 cabling, terminal-board connections, and system diagnostics.
How should GE IS215VPROH1BD be installed in the protection rack?
With rack power removed, slide GE IS215VPROH1BD into its designated slot, seat both levers, secure the captive screws, and reconnect documented cables.
What must be verified before returning GE IS215VPROH1BD to service?
After installing GE IS215VPROH1BD, confirm cabling, board diagnostics, TREG configuration, IONet communication, and the approved site trip-verification results.
