About the IS200DTRTH1ABA
Hardware Tips and Specifications
The Simplex DIN-railed Mounted Trip Transition Board IS200DTRTH1ABA is used to interface to the VTUR board alongside the DRLY board in the General Electric Mark VI Series. This model also permits up to six trip functions on the VTUR board which will interface with the DRLY model rather than the TRPG module. With some of the connectors on the DTRT board, there is the possibility for up to two VTUR boards to be connected. If two VTUR boards have been connected to the DTRT board, there is the possibility for the VTUR boards to control six relays. For every application in which a trip system between the DRLY and VTUR model is used, the IS200DTRTH1ABA model must also be used. Note that if only one VTUR model is required, under no circumstances can the DTRT be eliminated. The main components of the DTRT board are:
- three thirty-seven-pin D-type connectors
- two connectors labeled J1 and J2 used to cable from the two VTUR boards
- J3 connector is used to connect to the DRLY board
- three screws labeled TB1
- used for ground (SCOM) connection
While there are several other redundancy types that can be used with Mark VI models, the DTRT board can only be used with a simplex redundancy type. Please note that this model is known as a termination box board, with a plastic mounting holder to allow the model to be mounted in a DIN-rail capacity. For more information on the IS200DTRTH1ABA model, refer to the Mark VI Turbine Control GEH-6421C Instruction Manual for installation procedures.
