FUNCTIONAL DESCRIPTION:

IS230PCCAH1A is a Core Analog Power Connect Card manufactured and designed by General Electric as part of the Mark VIe Series used in GE Distributed Control Systems. The Power Connect Card (PCCA) serves as the link between the control electronics of the drive and the SCR power bridge. It uses pulse transformers to provide gate drive signals to the SCR bridge. The PCCA also incorporates snubber circuits, which mitigate voltage spikes across the AC lines, DC bus, and gate drivers for low- to medium-horsepower controllers. For higher horsepower systems, some or all of these snubber circuits are relocated to other areas of the setup. The Core Analog (PCAA) Module and the optional Core Analog (TCAT) Terminal Board facilitate analog signal processing within a gas turbine system. These modules support various functionalities, such as thermocouple inputs, 4-20 mA current loops, seismic inputs, Linear Variable Differential Transformer (LVDT) excitations and inputs, pulse rate inputs, and servo coil outputs. The PCAA module is compatible with both simplex and Triple Modular Redundant (TMR) systems, offering flexibility for different operational setups.

BOARD GROUPS:

The PCCA board is divided into ten distinct group numbers, which are assigned based on the system's voltage, frame size, and whether the power conversion is regenerative or non-regenerative. The armature voltage scaling varies according to the group number:

• G1, G7, G9 – Regenerative, 240 to 630 volts
• G2, G8, G10 – Non-regenerative, 240 to 700 volts

The PCCA board features four wire jumpers—JP1, JP2, WP3, and WP4—that are used to configure both the system voltage and the connections for the snubber capacitors.

CONFIGURABLE JUMPERS (JP and WP):

Jumpers JP1 and JP2 should be attached to the correct stab terminals, P3 through P10, based on the card group number and system voltage requirements. Jumpers WP3 and WP4 are responsible for linking stab terminals P2A to P2B, and P1A to P1B, respectively. These jumpers allow for selecting whether the PCCA snubber capacitors are connected to the same location on the power bridge as the voltage feedback channel.

FREQUENTLY ASKED QUESTIONS:

What is the purpose of the Core Analog Power Connect Card (PCCA)?

The PCCA serves as the interface between the control electronics and the SCR power bridge in drive systems, delivering gate drive signals and managing voltage feedback and snubber capacitor connections.

What are snubber capacitors, and why are they important?

Snubber capacitors help suppress voltage spikes that can occur across the AC lines, DC bus, and gate drivers. Proper connection of these capacitors ensures the system operates smoothly, especially in low- to medium-horsepower controllers.

How do jumpers JP1, JP2, WP3, and WP4 work on the PCCA board?

Jumpers JP1 and JP2 are used to connect stab terminals based on system voltage and group number. WP3 and WP4 are used to connect terminals P2A to P2B, and P1A to P1B, allowing you to configure whether the snubber capacitors are linked to the same point on the power bridge as the voltage feedback channel.
