IS200CABPG1A is a Control Assembly Backplane (CABP) Board manufactured and designed by General Electric as part of the Mark VI Series used in GE Drive Control Systems. The IS200CABP Control Assembly Backplane (CABP) board is a multi-layer printed wiring board that provides the interconnections for the printed wiring boards inserted into it and interfaces to external signals. The boards inserted will vary with the power level and application of the Innovation Series drive that the CABP board is part of. Connectors are also provided for various external interfaces such as user control inputs/outputs (I/O), four front panel meters, diagnostic/configuration tools, a front panel keypad, four ISBus ports, and power supply inputs. The CABP board is mounted to the Innovation Series board rack that provides the mounting points for the individual boards.
The CABP board is powered from a single IS200HFPA High-Frequency AC/Fan Power Supply Board (HFPA). Power connections are via a twisted/shielded pair cable for the 48 V AC power and a separate isolated twisted pair cable for the 17 V AC power. Isolation for these cables is 1000 V dc. The CABP board connects the isolated power returns to the control cabinet common (CCOM) either through an impedance (resistor/capacitor) or directly. It also connects DCOM to CCOM. Provisions are available to tie cable shields (when applicable) to the chassis directly. There are two application-specific stab-on connectors each for CCOM and Chassis Ground (GND). GND is tied to the board rack chassis through the mounting screws. CCOM and GND are tied together through a capacitor. The CABP board CCOM is connected to the control cabinet CCOM via the stab-on connectors.
