About the IS215VPROH2BC
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. 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
- 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
- to connect to the TPRO terminal board through an Ethernet cable when the IS215VPROH2BC model is operating as a turbine emergency trip processor board
The above-attached information is primarily reminiscent of a service technician-guided visual inspection of the IS215VPROH2BC Turbine Emergency Trip Board PCB itself.
IS215VPROH2BC Ratings and Revisions
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
