FUNCTIONAL DESCRIPTION:

IS200DDPTH1A is a Simplex Dynamic Pressure Transducer Input Terminal Board manufactured and designed by General Electric as part of the Mark VI Series used in GE Speedtronic Gas Turbine Control Systems. The Simplex Dynamic Pressure Transducer Input (DDPT) terminal board is a small, DIN-rail mountable acoustic terminal board. The board accommodates either Vibro-Meter® or Bently Nevada* transducers as two pressure transducers for monitoring pressure waves in gas turbine combustion chambers. Two cables are used to link it to the VAMA, and it is made to comply with Class 1, Division 2 environmental standards for hazardous gases.

INSTALLATION:

The DDPT board should be slid into the plastic holder after mounting it to the DIN rail. The 42-terminal permanent Euro-Block type terminal block should be connected with the pressure transducer wires. The most common type of wire is shielded twisted triplet #18 AWG. For the SCOM (ground) connection, ten screws are available. Connect the cables from the DDPT JR1 connector to the J3 connector on the front panel of the VAMA, and from the DDPT JR5 connector to the J5 connector on the lower half of the VME rack. The cables are secured by these locking connectors.

OPERATION:

VAMA supplies a ±24 V dc to the DDPT to power the pressure sensing equipment. VAMA/DDPT supports the following third-party vendor equipment:

  • Vibro-Meter Galvanic Separation Unit types GSI 1_
  • Bently-Nevada 86517 with modifications 142533 or 159840 charges amplifier
  • Bently-Nevada dynamic pressure charge amplifier 350500.

The Vibro-Meter GSI configuration conditions a pico-coulomb output from a dynamic pressure transducer (Vibro-Meter CP216 or CP231) through a charge amplifier (Vibro-Meter IPC 704) with an output current equal to roughly 125 A/psi. In order to represent the dynamic pressure (gain represented in mV/psi) riding on top of a dc bias voltage of about +7 V dc, the GSI unit outputs an ac signal (nearly 2 V peak). GSI unit needs a +24 V dc power supply. The PCOM on the terminal board is not often utilized, and the power supply return for the GSI is grounded externally. PCOM needs to only be utilized in the absence of an external return ground.

The dynamic pressure transducer charge signal is converted from pico-coulombs to milli-volts, which represents the pressure in psi, by the Bently-Nevada 86517 interface module. The interface module generates an ac signal (about 1.2 V peak) on top of a -10 V dc negative dc bias voltage. A -24 V dc power supply is necessary for the Bently-Nevada unit.

CONFIGURATION:

Two jumpers set the bias voltage for the transducers, and two jumpers set the power return from the transducers:

• JPA and JPB apply either a +28 V bias or –28 V bias to the transducer signals.
• JP2 and JP4 connect the transducer power return to PCOM or to Open.
