GE IS200TRPAH2A Multilin calibration module

Description:

GE IS200TRPAH2A Multilin calibration module

IS200TRPAH2A is an Aeroderivative Turbine Primary Trip terminal board developed by GE. 

Do not inadvertently connect the 240 V ac and dc voltages in 240 V ac applications. The peak voltage will exceed the MOV rating, causing the device to fail. Most ac supplies have a grounded neutral, and if an inadvertent connection between the 125 V dc and the ac voltage is made, the sum of the ac peak voltage and the 125 V dc is applied to MOVs connected between dc and ground. In 120 V ac applications, however, the MOV rating can withstand the peak voltage without failing.

Features

As part of the Mark VIe control system, the board interface with PTUR / YTUR I/O packs and TTUR terminal boards. The following are the inputs and outputs:

1.Twelve passive pulse rate devices (four per R/S/T section) measuring turbine speed by sensing a toothed wheel. Alternatively, six active pulse rate inputs (two per TMR section)

2.Two 125 V dc TMR voted output contacts for the trip coil to the main breaker coil.

3.Four 24-125 V dc voltage detection circuits for trip string monitoring

4.One 24-125 V dc 'Fail-safe' ESTOP input for disabling trip relays. Signals from TMR systems fan out to the PR3, PS3, PT3, JR4, JS4, and JT4 connectors.

System Design
1.The TRPA board is intended for use in two different ways. When a TRPA terminal board is used to connect three PTUR or YTUR I/O packs to a TTUR terminal board, three cables with DC-37 pin connectors on each end can be used.

2.The TRPA provides two contact-voted trip relay outputs, ESTOP, and four voltage sensors in this mode of operation.

3.TTUR has the standard set of features described for that board. The TRPA speed inputs are inactive and should not be used with this board configuration.

4.The TRPA board can also be used with three I/O packs attached to it directly. The speed inputs to TRPA become active paths into the I/O pack in this mode of operation, allowing for a single terminal board primary trip solution.
