GE IS200TBCIH1CA VME TURBINE CARD is available in stock

FUNCTIONAL DESCRIPTION:

IS200TBCIH1CA is a Contact Input Group Isolation Terminal Board manufactured and designed by General Electric as part of the Mark VIe Series used in GE Distributed Control Systems. The contact input terminal board (TBCI) accepts 24 dry contact inputs wired to two barrier-type terminal blocks. DC power is wired into TBCI for contact excitation. The contact inputs have noise suppression circuitry to protect against surge and high-frequency noise. In the Mark VIe system, the PDIA I/O packs plug into the TBCI. One, two, or three PDIA packs support a variety of system configurations. Mark VIe requires the C version of this board for correct mechanical alignment of connector JT1 with I/O pack mechanical support.

• 
• INSTALLATION:The 24 dry contact inputs are wired directly to two I/O terminal blocks mounted on the terminal board. These blocks are held down with two screws and can be unplugged from the board for maintenance. Each block has 24 terminals accepting up to #12 AWG wires. A shield terminal strip attached to the chassis ground is located immediately to the left of each terminal block. For a simplex system connector JR1 is used; for a TMR system, all three connectors are used. Cables or I/O packs are plugged in depending on the type of Mark VI or Mark VIe system, and the level of redundancy.

  OPERATION:

  Filters reduce high-frequency noise and suppress surge on each input near the point of signal entry. The dry contact inputs on H1 are powered from a floating 125 V dc (100-145 V dc) supply from the turbine control. The 125 V dc bus is currently limited in the power distribution module before feeding each contact input. H2 and H3 versions use lower voltages as shown in the specification table. The discrete input voltage signals pass to the I/O processor, which sends them through optical isolators providing group isolation and transferring the signals to the system controller. The reference voltage in the isolation circuits sets a transition threshold that is equal to 50% of the applied floating power supply voltage. The tracking is clamped to go no less than 13% of the nominal rated supply voltage to force all contacts to indicate open when the voltage dips below this level.
