About the IS215VPROH2BC
The IS215VPROH2BC model was designed to work as both a turbine-based emergency trip as well as a turbine protection board. It is primarily used as the input/output processor board for the TPRO and TREG boards. The TREG board is the model used when the VPRO is interfacing with the turbine emergency trip board. The TPRO model is used with the VPRO in a turbine protection application. The Mark VI Turbine Control System Series containing this IS215VPROH2BC Turbine Emergency Trip Board, as they are both known at length, exists with a specific set possible application in the control and management systems of General Electric-compatible gas, steam, and wind turbine automated drive assemblies. This must be characterized as quite the significant functional upgrade from the previous industry-standard Mark V Turbine Control System Series of just about the same full extended series title, as the Mark VI Series added the increasingly-important alternative energy-based wind turbine possible functional envrionment onto the gas and steam-based rudimentary settings seen earlier on with the rollout of the Mark V.
Hardware Tips and Specifications
The I/O signal types when the VPRO model is being used with a TREG board are, economizing relays, emergency stop inputs, trip interlock inputs, and trip solenoid drivers. There are also a set number of I/Os per processor. For example, there are seven trip interlock inputs with three trip solenoid drivers per available TREG board. Please note that when the IS215VPROH2BC model is operating as a turbine emergency trip processor board it also has the ability to connect to the TPRO terminal board through an Ethernet cable. When the IS215VPROH2BC board is being used in a protection module application the primary purpose is to ensure that the chosen turbine does not experience any type of overspeed. A vital note needed when operating this model is that it will always be triple redundant and will have three totally separate and independent sections which will be named X, Y, and Z. The model has the capability to shut down one of the sections while the turbine is running without potentially compromising the protection system. Please note that the VPRO board will have its own onboard power supply that will generate between five and twenty-eight volts of direct current from the one-hundred twenty-five volts of direct current which will be taken from the cabinet PDM.
The above-attached information is primarily reminiscent of a service technician-guided visual inspection of the IS215VPROH2BC Turbine Emergency Trip Board PCB itself. While this may be true, this IS215VPROH2BC Turbine Emergency Trip Board device's Mark VI Series is actually relatively well-contextualized online within a wealth of originally-pertinent instructional manual materials. For starters, this IS215VPROH2BC Turbine Emergency Trip Board device has an average solenoid response time of 0.1 second, which of course pertains to the numerous trip solenoid components made available to this IS215VPROH2BC Turbine Emergency Trip Board device's base printed circuit board. On top of this, this IS215VPROH2BC Turbine Emergency Trip Board product offering makes use of trip solenoid circuits that are rated for the NEMA class E creepage level, with the ability to clear a maximum fuse voltage rating of 15 A for this process. This IS215VPROH2BC Turbine Emergency Trip Board unfortunately cannot be defined as the originally-developed product of its specific GE Mark VI Turbine Control System Series functional product role, as that would have to be highlighted as the IS215VPROH2 parent Turbine Emergency Trip Board notably not taking advantage of this IS215VPROH2BC Turbine Emergency Trip Board product's two-fold significant revision table. This IS215VPROH2BC Turbine Emergency Trip Board device's specific revisions include the:
- B-rated primary functional product revision
- C-rated secondary functional product revision
