About the IS200TRPLH1A
This IS200TRPLH1A Turbine Primary Trip Board printed circuit board product offering from General Electric was originally designed and manufactured specifically for placement in the Mark VI Turbine Control System Series, as should have been made obvious in our brief IS200TRPLH1A Turbine Primary Trip Board product description paragraph stored above. The Mark VI Series that this IS200TRPLH1A Turbine Primary Trip Board product belongs to is a significant upgrade upon its preceding Mark V Turbine Control System Series of the same full extended Mark Series title, as the Mark V Series has a more restricted set of possible functional applications in gas and steam turbine-based applications alone; completely shirking the coming Mark VI Series' possible alternative energy-minded wind turbine functional applications. This IS200TRPLH1A Turbine Primary Trip Board's greater Mark VI Series is additionally seen as an attractive GE Mark product series given its nature as one of the trusted brand's final-developed Mark Series to utilize the patented Speedtronic control system technology across quite the wide swathe of GE products.
Hardware Tips and Specifications
The IS200TRPLH1A functions as a Large Steam Turbine Primary Trip terminal card used as the primary protection from overspeed when used in conjunction with large steam turbines. Control of the board is placed on the turbine protection controller card, typically a VTUR or PTUR board depending on the system type. The TRPL board can be used in a Mark VI or Mark VIe Control System, as mentioned above. When the model is used in a Mark VI control system the model will be controlled by the VTUR and is only supported in TMR applications. When the model is used with the Mark VIe Control it is controlled by the PTUR I/O packs on the TTURH1C model and is only supported in TMR applications as well. The model also works in conjunction with a TREL board to provide emergency/primary interfaces to the ETDs. The TRPL board provides the negative side of the 125 VDC to the trip solenoids while the TREL offers the positive side. Together the TREL and TRPL board can connect up to three solenoids. The IS200TRPLH1A is populated by two large terminal strips with a total of 48 connector points. It also has three d-shell connectors, MOV (metal oxide varistors) diodes, resistors, transistors, integrated circuits, wire jumpers, and nine magnetic relays.
The relays on this board are in three voting circuits that interface with three trip solenoids. The solenoids use two out of three contact voting, and trip circuits include solenoid suppression and voltage monitoring. This IS200TRPLH1A Turbine Primary Trip Board product offering, not unlike any other relevant Mark VI Series product offering, is at least contextualized onlne through a series of product-specific installation and replacement requirements. These requirements are oftentimes considered crucial to understand given the possible presence of potentially-damaging or even lethal IS200TRPLH1A Turbine Primary Trip Board surface voltages on its base printed circuit board. Some of this IS200TRPLH1A Turbine Primary Trip Board product's installation requirements include:
- Usage of a standard wrist grounding strap
- Connection of several wires for three trip solenoids directly to the first I/O terminal block
- Additional wire connections for primary emergency stop and optional secondary terminal block emergency stops
- Final trip power solenoid connection
